[PvE Guide] Destruction in Legion 7.3

Warlock
1 2 3 15 Next
Introduction
Hedo is switching mains in Legion, so I'm going to take up maintaining a Destruction guide, compiling theorycrafting information into one place to build an informative PvE reference.

Foreword
This guide will be an iterative work on my part, so there will need to be revisions as time goes on and more players figure things out/perfect sims for theroycrafting. Feel free to point out anything you feel isn't accurate, especially if you've got any sources to show as much, as well as anything that might be missing from this guide. [Anything in square brackets is either super WIP, needs confirmation or more info].

    Navigating this Guide
    To find a specific section of this guide, use ctrl+f (Find...) and search for "[Section]-[Subsection]". For example, if you wanted to find the section on Artifact Traits, you would search "3-2".

    Section 1 - Legion Changes
    Destruction has seen a few baseline changes worth mentioning before delving into the rest of the guide. Most of this will be touched on in more detail in the Rotation section.

    1-1 Soul Shards and Soul Shard Fragments
    Burning Embers have returned. Sort of. As of 7.2.5, Soul Shards for Destruction have been broken down into 10 Soul Shard Fragments each.

    Our Fragment generators are:
    Incinerate, generating 2 Fragments and an additional Fragment on a crit.
    Immolate, having a 50% change to generate a Fragment. This is guaranteed on a crit.
    Conflagrate, generating 5 Fragments.

    Our Shard spenders are still Chaos Bolt and Rain of Fire, costing 2 and 3 Soul Shards respectively.

    1-2 The Scepter of Sargeras
    We no longer have weapon drops in Legion, but we have a spec specific Artifact weapon: The Scepter of Sargeras. This staff serves as our character progression throughout the max level experience in Legion, providing a number of Traits ranging from a new ability, Dimensional Rift, to increases in damage to several spells (See section 3 for more details). Throughout Legion, you'll earn Artifact Power and Artifact Knowledge, which increases Artifact Power drops for that character, that can be used to gain Traits. There are also hidden effects that the Artifact has. A list of all know hidden and PvE relevant effects can be found below... when some are discovered.

    Section 2 - Stats and Gearing
    2-1 Stats and How They Affect You
    Intellect:
  • Increases your Spell Power at a rate of 1 Int = 1 SP.
  • Spell Power increases the damage done by all of your spells.
  • Critical Strike:
  • Gives most of your spells a random chance to deal additional damage (around double in PvE).
  • Increases the damage dealt by Chaos Bolt at flat rate (eg. 20% Crit rating increases Choas Bolt's damage by 20%).
  • Haste:
  • Reduces the cast time of all your spells.
  • Increases the rate at which Damage over Time spells (Immolate) tick.
  • Reduces the cooldown of Conflagrate charges.
  • Mastery:
  • Causes your spells to deal X% increased damage, plus up to X% extra damage.
  • Causes damage you take to be reduced by Y%, plus up to Y% extra damage reduction. Y is roughly one fifth of X.
  • Versatility:
  • Increases all damage and healing done by a percentage.
  • Reduces the damage taken by half of the above percentage.
  • Multistrike...?
    Multistrike has been removed in Legion and has been replaced by another stat on old gear.

    2-2 Racial Bonuses
    Alliance
    Dwarf:
    Might of the Mountain - Increases your critical strike damage/healing by 2%.
    Gnome:
    Nimble Fingers - Increases haste by 1%.
    Human:
    The Human Spirit - Increases all secondary stats by 2% from all sources.
    Worgen:
    Viciousness - Increases critical strike chance by 1%.

    Horde
    Blood Elf:
    Arcane Acuity - Increases critical strike chance by 1%.
    Goblin:
    Time is Money - Increases haste by 1%.
    Orc:
    Blood Fury - Increases your Spell/Attack power by 2243 (at level 110) for 15 seconds. 2 minute cooldown.
    Troll:
    Berserking - Increases your haste by 15% for 10 seconds.
    Undead:
    Touch of the Grave - Your spells have a small chance to deal extra damage to the target, healing you for the same amount.

    2-3 Tier Bonuses, Legendaries and Other Notable Items

    Legendaries
    In Legion, Legendary items have been introduced as world drops, giving you a bonus similar to Epic world drops of old. They can range from bonuses for any class, ranged, Warlocks or Destruction specifically. They currently drop from PvE bosses, World Quest Chests and PvP strongboxes. You will start only being able to equip one legendary at a time, increasing to two through your Order Hall research.
    • Prydaz, Xavaric's Magnum Opus - Neck - All Classes: Every 30 seconds, gain an absorb shield for 25% of your max health.
    • Sephuz's Secret - Finger - All Classes: Successfully applying a loss of control effect, interrupt or dispell grants you 70% increased movement speed and 25% Haste for 10 seconds. This effect may only occur once every 30 seconds.
    • Kil'jaeden's Burning Wish - Trinket - DPS: Launch a vortex of destruction that seeks your current enemy. When it reaches the target, it explodes, dealing a critical strike to all enemies within 10 yds for 1121640 Fire damage.
    • Norgannon's Foresight - Feet - Warlocks, Priests and Mages: Standing still for 8 seconds grants you Foresight, allowing you to cast while moving for 5 seconds.
    • Soul of the Netherlord - Finger - Warlocks: (Destruction) You gain the Eradication talent
    • The Master Harvester - Chest - Warlocks: Each Soul Shard you spend has a 6% (Destruction) change to grant you Soul Harvest for 8 seconds.
    • Pillars of the Dark Portal - Legs - Warlocks: Demonic Gateway now casts instantly and you can use Demonic Gateways twice before triggering a cooldown.
    • Alythess's Pyrogenics - Finger - Destruction: Enemies effected by your Rain of Fire take 10% increased damage from your Fire spells.
    • Odr, Shawl of the Ymirjar - Back - Destruction: Enemies marked by your Havoc take 8% increased damage from your single target spells.
    • Feretory of Souls - Waist - Destruction: Casting a damaging Fire spell has a 10% chance to generate a Soul Shard.
    • Magistrike Restraints - Wrist - Destruction: Chaos Bolt has a 20% chance to strike an additional enemy within 30 yards.
    • Lessons of Space-Time - Shoulders - Destruction: While you have a Dimensional Rift open, all your damage is increased by 10%


    2-4 Stat Builds, Gems and Enchants
    These priorities will change based on Talent choices, Artifact progression and target counts. The priorities and enchants/gems suggested below will provide a good stat priority for most situations.

    Stat Priorities
    Generally: Intellect => Haste > Crit > Vers > Mastery

    For more accurate stat weights for your character, you should sim yourself. For more information you can read the following guide:
    https://docs.google.com/document/d/1pW5mWY9nkfWoRCOHfoXqeeGb8s-jMoSVy-g8uveUv4c/preview#heading=h.3lsngyuiznm9

    Note: If you invest heavily in mastery, you will experience swings in damage from fight to fight based on how lucky you are. If you would rather have a more consistent build, consider avoiding Mastery in favor of other stats

    Gems
    Currently, socketing Haste gems should be your priority. You may also have one Saber's Eye of Intellect in your equipped armour, but these are expensive, so socket these wisely.

    Enchants
    For Ring enchants, Haste should also be your priority. Cloak enchants are main stat, so use Intellect.

    Neck Enchant
    Mark of the Claw is currently our best neck enchant.

    Food, Flasks and Pots
    You should be using Haste food, Flask of the Whispered Pact and Potion of Deadly Grace or Potion of Prolonged Power (these are about neck and neck in performance, PP pulling ahead on multitarget).

    Section 3 - Talents and Artifact Traits/Relics
    3-1 Talents
    Talents have been through a significant rework in Legion; there are many more Talents that effect your DPS throughput now and not in a "Pick Your Different Flavour of AoE/Single Target/Cleave Talent in this Row" structure either. As such, there are a lot of different set ups for a lot of different situations where you'd want to change talents; many different setups may even excel on a per Boss basis. My aim with this section is to provide an optimal pure ST build and the basis for a dungeon build, then examine each row to show why you would deviate or stay with the suggested Talents on each row.

    Talent Calculator: http://legion.wowhead.com/talent-calc/warlock/destruction

    Suggested ST Build
    Tier One: Backdraft
    Tier Two: Eradication
    Tier Three: Demonic Circle
    Tier Four: Soul Harvest
    Tier Five: Demon Skin or Dark Pact
    Tier Six: Grimoire of Service
    Tier Seven: Channel Demonfire

    Suggested Dungeon Build [This will likely go through several iterations soon]
    Tier One: Backdraft
    Tier Two: Eradication or Empowered Life Tap
    Tier Three: Shadowfury
    Tier Four: Cataclysm or Fire and Brimstone
    Tier Five: Burning Rush or Demon Skin
    Tier Six: Grimoire of Sacrifice
    Tier Seven: Any

    Tier One:
  • Backdraft: Casting Conflagrate reduces the cast time of your next two Incinerate or Chaos Bolt casts by 30%.
  • Roaring Blaze: Conflagrate increases your remaining Immolate damage on the target by 25% until Immolate is refreshed or expires.
  • Shadowburn: Blasts a target for 316% Spell Power. Generates 5 Soul Shard Fragments plus an additional 5 if the target dies within 5 seconds. Replaces Conflagrate, 12 second CD.
  • Discussion: Backdraft is your go-to for this tier. Roaring Blaze currently doesn't perform better than Backdraft in almost any scenario. Shadowburn is very niche and is only a good pick where you can get 2 shards incredibly consistently (basically every 12 seconds).

    Tier Two:
  • Reverse Entropy: Chaos Bolt and Rain of Fire restore 35% of your maximum mana and their damage is increased by 10%.
  • Eradication: Chaos Bolt increases damage dealt to the target by 15% for 7 seconds.
  • Empowered Life Tap: Life Tap now grants you 10% increased damage for 20 seconds. This duration can pandemic (max 25 seconds when refreshed).
  • Discussion: In single target and 2 target cleave, Eradication is your best choice; 3 or more targets and ELT performs better.

    Tier Three:
  • Demonic Circle: Summons a Demonic Circle for 6 minutes, allowing you to teleport to its location and remove all movement slowing effects. Limit 1. 0.5 second cast.
  • Mortal Coil: Horrifies an enemy target into fleeing, Incapcitating them for 3 seconds an healing your for 20% maximum health. You will be healed even if the target is not effected by the Horrify.
  • Shadowfury: Stuns all enemies within 8 yards for 4 seconds. 1.5 second cast time. 30 second cooldown.
  • Discussion: Demonic Circle is going to be your go-to for raids, unless you specifically require a stun. Shadowfury is good for dungeons, specifically in Mythic+. Mortal Coil's heal can be useful, but for the most part is too niche for general PvE use.

    Tier Four:
  • Fire and Brimstone: Incinerate now hits all enemies near the target and generates 1 Soul Shard Fragment per target.
  • Cataclysm: Conjures a cataclysm at the target location, dealing 750% Spell Power Shadowflame damage to all enemies within 8 yards and afflicts them with Immolate. 2.5 second cast. 30 second cooldown.
  • Soul Harvest: Increases the damage of you and your pets by 20%. Lasts 12 seconds, increased by 4 seconds for each target afflicted by Immolate, up to a maximum of 36 seconds. Casting this does not incur a GCD.
  • Discussion: Soul Harvest is your best choice for 1 and 2 targets. For 3+, both Cataclysm and FnB are good options, with Cataclysm being preferable for periodic adds and FnB better for constant cleave.

    Tier Five:
  • Demon Skin: Your Soul Leech now recharges by 1% maximum health every second, and you may now absorb up to 20% maximum health.
  • Burning Rush: Increases your movement speed by 50%, but also damages you for 4% of your maximum health every 1 sec. Movement impairing effects may not reduce you below 100% of normal movement speed. Lasts until cancelled.
  • Dark Pact: Sacrifices 20% of your current demon's health to shield you for 400% of the sacrificed health for 20 seconds. If you have no demon active, your health is sacrificed instead. Usable while under control impairing effects.
  • Discussion: You should use Demon Skin or Dark Pact in raids unless you need the movement speed of Burning Rush for a very important mechanic, but most of these can be handled similarly with Demonic Circle. Demon Skin gives the most value when incoming damage is frequent and Dark Pact will present the most value when damage is infrequent and very high (its also far stronger with GrimSac given it will use your Health Pool instead of your pets). In dungeons, Burning Rush is desirable when flying through easier dungeons (especially low M+), but you lose a fair amount of survivability, so use at your discretion.

    Tier Six:
  • Grimoire of Supremacy: Doomguard and Infernal can now be used as permanent pets.
  • Grimoire of Service: Summon a second demon for 25 seconds that deals 100% increased damage. 1.5 min cooldown. They will additionally perform their utility action on summon.
  • Grimoire of Sacrifice: Sacrifice your current demon to gain Demonic Power, which causes your spells to sometimes deal 100% Spell Power Shadow damage to the target and enemies within 8 yards. Approx. 20 RPPM. Lasts 1 hour or until another permanent Demon pet is summoned.
  • Discussion: Some important things to note about this tier: Sacrifice no longer gives you a spell on Command Demon, so choosing which demon to summon does not matter as this talent prevents you from using a pet's Command Demon ability without re-summoning. Also, Supremacy changes Lord of Flames to be activated on an Infernal's Meteor Strike ability (which you should turn off auto-cast to control when it is used).
    For 3 or more consistent targets, use Sacrifice. In ST, Service and Supremacy are neck and neck, with Supremacy just ahead. Service ends up being more practical for progression and burst.

    Tier Seven:
  • Wreak Havoc: Havoc's cooldown is reduced by 20 seconds.
  • Channel Demonfire: Launches 15 bolts of felfire over 3 seconds to random targets afflicted with Immolate. Each bolt deals 100% Spell Power Fire damage and dealing 50% Spell Power Fire damage to all nearby enemies. 25 second cooldown, reduced by haste.
  • Soul Conduit: Each Soul Shard spent has a 15% chance to be refunded.
  • Discussion: In ST, CDF is your best choice. Wreak Havoc should be used when there is 2 to 3 consistent priority targets. At 4 targets and above, SC could pull ahead, especially when coupled with FnB.

    3-2 Artifact Traits
    Artifact Calculator: http://legion.wowhead.com/artifact-calc/warlock/destruction/AqSCImA

    Active Ability - Dimensional Rift
    The first trait you receive with the Scepter is Dimensional Rift. This is an instant cast spell with 3 charges and a 45 second cooldown. This spell will open one of three rifts, chosen randomly, to deal damage to your current target, additionally generating 3 Soul Shard Fragments. This can be in the form of a huge chunk of Fel (Chaos Tear), a rapid fire succession of Shadowfel bolts (Unstable Tear) or a slower slew of Shadow bolts (Shadowy Tear). These currently appear to not have infinite range and will cease dealing damage if their target moves out of their range. Use of this ability will be covered more in the Rotations section.

    Golden Traits
    • Dimension Ripper: Incinerate has a 5% chance to grant a charge of Dimensional Rift.
    • Lord of Flames: Once every 10 minutes, your Summon Infernal (Infernal's Meteor Strike with GrimSup) summons 3 extra Infernals for 25 seconds.
    • Conflagration of Chaos: Conflagration has a 50% chance to guarantee your next Conflagrate critically strikes, and to increase its damage by your critcal strike chance.
    • Flame Rift: (7.2 Trait) Dimensional Rift can now summon a powerful Flame Rift, casting Searing Bolt 20 times over ~8 seconds. Searing Bolt deals 100% Spell Power Fire damage and an additional 140% Spell Power Fire damage over 20 seconds, stacking up to 20 times.

    Other interesting Traits
    • Soul Snatcher: Chaos Bolt has a 3% (+3% for each addition level) to refund 1 Soul Shard.
    • Demonic Durability: Reduces the cooldown of your Unending Resolve by 30 seconds.
    • Eternal Struggle: After casting Life Tap, you take 3% (+3% with each level) less damage for 6 seconds
    • Planeswalker: Transporting through your Demonic Gateway increases your movement speed by 30% for 6 seconds.
    • Cry Havoc: (7.2 Trait) When Chaos Bolt strikes a target marked with Havoc, it explodes dealing 100% Spell Power damage to nearby enemies.

    Golden Trait Shortest Paths
    Getting to each Golden Trait the cheapest way possible is rather simple with the Scepter. The following are the shortest paths to each starting from Flames of the Pit (the trait immediately following Dimensional Rift).

    Flames of the Pit --> Devourer of Life --> Residual Flames --> Conflagration of Chaos

    Flames of the Pit ---> Eternal Struggle ---> Burning Hunger ---> Lord of Flames

    Flames of the Pit ---> Master of Disaster OR Fire From The Sky ---> Demonic Durability ---> Fire and Flames OR Soulsnatcher ---> Chaotic Instability ---> Dimension Ripper

    Following these paths in any order will not increase the total amount of Artifact Power you need to unlock all 3 as quick as possible so long as you only get one of the two traits in both forks in the Dimension Ripper path.

    Suggested Trait Path
    To get the most out of your early Artifact Traits, you should look to get Impish Incineration (Lord of Flames path, detour after Eternal Struggle), then Lord of Flames, then Conflagration of Chaos, and lastly Dimension Ripper before filling out the rest of the Artifact.

    For those looking to min-max their path:
    https://cdn.discordapp.com/attachments/146682707756187658/214946089294364682/ARTIFACTFINISHFINISH.png

    7.2 Suggested Trait Path
    After you reach the Broken Shore for the second time and have 35 Artifact traits, you will soon unlock a new set of Traits as well as a 4th rank in all 3 rank traits. Once you unlock these, its suggested you get all the new Traits first, then the 4th ranks in older Traits in the same order as your Relic priorities.

    3-3 Artifact Relics
    Artifact Relics are drops from the world, dungeon bosses and raids that enhance your artifact in two ways. They provide an item level boost to your Scepter, increasing its stats. Relics also add a rank to one of the traits in your Artifact that have multiple ranks, further increasing the benefit they provide. You will start with 2 Relic slots and unlock a 3rd by completing your Class Order Campaign. Selection of which relics to use will mostly come down to ilevel when leveling, so prioritise higher ilevel relics until you can be picky about the traits the relics buff.

    Relic sims can be found here:
    http://lockonestopshop.com/#!/Destruction/Sims/Relic

    3-4 What about Glyphs?
    The glyph system has been reworked and Major Glyphs have been removed; all glyphs are now cosmetic only.
    Section 4 - Rotations
    As mentioned, Talents have a lot more noticeable effect on your DPS and, as you can probably imagine, many of them can have a big impact on your priorities and rotation. Like the Talent section, I'm going to provide a baseline set of priorities and then talk about more advanced aspects of them, specifically surrounding Talents, and how to incorporate them into the basic priorities.

    4-1 Basic Single Target Rotation
    This subsection is intended as a quick reference for players unfamiliar with the Destro spellbook. More advanced tips can be found in the following sections.
    • Keep Immolate up as close to 100% of the time as possible.
    • Cast Chaos Bolt under either of the following scenarios:
      • A) Damage increasing effects are active (trinket procs, Soul Harvest, encounter mechanics that increase damage, etc.)
      • B) You are about to cap at 5 Soul Shards. Its suggested to cast Chaos Bolt at ~4.5 Shards unless deliberately building towards 5 for burst.
    • Keep one charge of Conflagrate on cooldown, saving one for burst or movement.
    • Keep one charge of Dimensional Rift on cooldown, saving two for burst or movement. (Save only one charge once you get Dimensional Ripper to ensure you get the most out of the trait).
    • Cast Incinerate

    4-2 Basic Multiple Target Rotation
    Once you encounter more than one target, your priorities need to change.

    At 2 Targets:
    • Keep Immolate up on both targets.
    • Use Havoc to cleave powerful spells onto both targets eg. Chaos Bolts/Shadowburns/Roaring Blaze Immolates.
    • Continue ST rotation otherwise.

    At 3+ Targets:
    • Keep Immolate up on 3-5 targets
    • Cast Rain of Fire when 3+ targets are present, 4+ targets if you can Havoc cleave Chaos Bolts instead
    • Keep one charge of Conflagrate on cooldown, saving one for burst or movement.
    • Keep one charge of Dimensional Rift on cooldown, saving two for burst or movement. (Save only one charge once you get Dimensional Ripper to ensure you get the most out of the trait).
    • Cast Incinerate

    4-3 Opening Sequence
    • (~3 seconds before pull) Pre-pot
    • Pre-cast Incin
    • Pre-cast Immolate
    • (Pull)Conflag
    • Pet CDs
    • Rifts
    • SH
    • Conflag
    • Continue normal rotation

    Notes: You can fit a second pre-casted Incinerate at max distance, in which case you should start pre-casting at ~5 seconds.
    With CDF + Eradication, you should cast your first CDF after your first CB lands. Otherwise after SH is up.

    4-4 Advanced Rotation
    Roaring Blaze
    When choosing this Talent, you will no longer be saving Conflags for burst or movement, instead saving them to buff a Pandemic'd Immolate (18 sec + 5.4 = 23.4 seconds long). You will end up weaving Immolates like this:
    Buffed Immolate -> Immolate falls off -> Standard Immolate til all Conflag charges gained -> Buffed Immolate -> ...

    The number of Conflags you should use on a single Immolate varies depending on T19 2pce and Haste procs/cooldowns; generally you should use all your banked charges plus one additional charge as it comes off cooldown. You should use one extra charge (possibly 2 with T19 2pce) during lust/hero/warp or similar Haste buff.

    To minimise the time that Immolate is not on your target, you should cast Immolate with about 1 second left on a buffed Immolate, which will allow the buffed Immolate to get its partial tick out and have an Immolate reapplied soon after. Keep this Immolate rolling as normal until you are about to max Conflag charges, at which point you should apply Immolate such that you get the full duration, then cast your Conflags, rinse and repeat.

    TL;DR: Your use of Immolate and Conflag should look like this (assume we already have a standard Immolate up):
    Pool all Conflags -> Reapply Immolate to max out duration (~23 seconds) -> Use all Conflags -> Use one more Conflag off cooldown -> Start casting Immolate with < 1 second left on Immolate (letting Immolate fall off) -> Pool all Conflags -> Repeat

    Eradication
    When using Eradication, you will not be able to keep this buff up 100% of the time (at least not without absurd RNG/luck, haste and/or Legendary), so you should aim to keep this buff up during important damage windows (big buffs, mechanics, etc).

    To keep this buff up for as long as possible, you should aim to "clip" your target with a Chaos Bolt as late into the buff as possible. This means you want to cast 1-2 other spells inbetween Chaos Bolt applications. The exact time/spells/casts you can fit in between Chaos Bolt casts will depend on haste and which spells you cast.

    Movement
    Destruction has trouble dealing damage on the move, and in Legion we have very few options for something to cast when we are forced to move. Taking Demonic Circle and planning positioning can minimise the amount of movement you'll be forced into. When you are forced to move, your options are rather small:
    • Havoc (only when you can benefit from cleaving spells with it).
    • Life Tap (except when talented into RE)
    • Dimensional Rift.
    • Conflag/Shadowburn (except when talenting Roaring Blaze).

    Life Tap and Movement
    tl;dr: In encounters with movement, you should float low % Mana when not moving and prioritise casting it when you're forced to move.

    Life Tap is one of the few instants we have to use on the move, so its important that when we have to move we can cast it so that we have more casting options on the move, possibly saving more important instants and ensuring we can continue our rotation even when forced to move. However, it doesn't give us value unless it refills mana, because tapping when it won't is just hurting yourself and eating GCDs with no benefit.

    To make sure that we can Tap on the move and get value out of it, we should aim to float at reasonably low mana while not moving. This allows you to focus more on casting other spells while you don't have to move and gives you up to 3 more GCDs that can be filled while moving that isn't Conflag or DR.

    5 - Useful Addons and Macros

    5-1 Addons
    Addons can be an incredibly valuable addition to your WoW experience and performance when used correctly. While specific addons and functionality are largely preferential, this subsection will list some of the widely recommended addons to help play your character as best you can.

    WeakAuras 2:
    A very powerful addon capable of displaying auras for practically anything you can think of. Ability CDs, proc durations, fight mechanics and more, its easily one of the more important addons to consider using when playing any class. Whilst it's setup can be quite involved, you can import other people's WA setups using import strings.
    • Not's Spec WAs: https://notsthoughts.wordpress.com/2016/07/25/weak-aura-hosting/

    TellMeWhen:
    A simpler alternative to WeakAuras. Whilst its capable of less then WA, its far easier to get started without assistance. I've personally used this throughout WoD and would highly recommend this to anyone that feels WA seems too intimidating or hard to work with.

    TidyPlates:
    A simplistic addon useful for showing DoT/Debuff durations on targets and generally making it easier to play in a multi-target situation. Certain other addons include this function as part of their setup, i.e. ElvUI.

    Deadly Boss Mods, BigWigs, or any other encounter-assistance addons:
    Not a Warlock specific addon, but these do help increase your DPS and survivability by making it easier to not mess up encounter mechanics.

    GTFO:
    A pretty simple addon, it will play annoying noises when you take damage, particularly to unavoidable damage in dungeon/raid encounters. Good if you want extra cues for when you mess up.

    5-2 Macros
    Warlocks aren't too reliant on Macros to perform well, but they are a useful tool to improve the usability of some spells in order to increase your performance. In this subsection, I'll be listing useful, common macros.

    Stop-cast Shadowburn
    This macro will cancle any spell being currently cast to cast Shadowburn. Useful when Shadowburn sniping for Shards.
    #showtooltip Shadowburn
    /stopcasting
    /cast Shadowburn

    Mouseover Havoc
    This macro will cast Havoc on a target your mouse is hovering over.
    #showtooltip Havoc
    /cast [@mouseover] Havoc

    Replace Demonic Circle
    This macro will remove your current Circle and replace it at your current location. Note: Due to the redesign of Demonic Circle, this macro will go on cooldown with the use of Demonic Circle since it has to cast it to replace the circle.
    #showtooltip Demonic Circle
    /cancelaura Demonic Circle
    /cast Demonic Circle

    5-3 Logs
    Logs are an incredibly valuable resource when trying to evaluate and improve your performance with any class, as well as for finding errors or possible problems in how your raid is handling encounters. If you want to try to improve your DPS beyond the advice of this guide, this is your next step.

    How to Log:
    Hedo's logging guide in the Warlock forums is a very good resource for learning how to get started using Warcraftlogs. It can be found here: http://us.battle.net/wow/en/forum/topic/15538506318

    How to Receive Help with Evaluating Your Logs:
    There are plenty of Warlocks that frequent the forums that are more than happy to help you improve as long as you have logs. You can either post in this thread or make a thread of your own along the lines of "LF [Spec] DPS Help, Includes Logs".

    Brusalk's Destruction Guide on MMO-C
    A fantastic guide with a thorough breakdown of many aspects of the spec including Talent choices/spells. I highly suggest reading this if you are interested in the "why" of aspects of this guide's suggestions.
    Pulled clarifying information on Talent choices as well as some advanced rotation information from here.
    http://www.mmo-champion.com/threads/2058233-Legion-Brusalk-s-Destro-Guide

    Furty's Destruction Guide on Icy Viens
    Pulled information, particularly about Talents, from this to supplement other sources and discussions.

    MMO-C Beta Discussion
    A very long thread discussing a ton of aspects of the spec as it was evolving, spattered with math and logs. A lot of preliminary information was pulled from this thread:
    http://www.mmo-champion.com/threads/1897069-BETA-Destruction-Warlock-Discussion

    Wowhead
    Spell data, beta build changes, Artifact and legendary item information. A lot of non-performance information has been pulled from here.

    Special Thanks
    A special thanks to Gahddo, Silver, Not, Motoko and others for their hard work theorycrafting, simming and the like for the community. Also thanks to Trixxa and Affides for passing along new info/info I missed, as well as anyone who pointed out errors/inaccuracies in this guide.

    Section 7 - Conclusion

    This is the first time I've written a guide on anything WoW related and, whilst I'm not a theorycrafter or Top 50 raider by any stretch of the imagination, I'm dedicated to keeping this a relevant reference for PvE for Destruction in Legion. This will require some iteration on my part as tuning and actual raiding begins, but hopefully whenever you saw this guide you got something out of it!

    One last time, but if you see anything in this guide that's incorrect, misleading, etc. post in this thread with something you feel needs to be corrected. If you just have any extra sources for me to pull information from, I'd love to see them.

    Looking good man, I'll probs start mine the night before prepatch.....
    Thanks Nakkiel. Were you doing a Demonology guide?
    Are we sure on that stat weight? I've been prioritizing as haste > crit > master = vers with low ilvl gear just to get over the GCD/cast speed humps?

    Beyond that great guide, got my destro artifact on my non broken warlock up to speed so I can play around a bit more with it, hopefully I get that sexy havoc legendary.

    That's actually a good point, regardless of whether that priority is correct. I got that priority from discussions in that mmoc thread talking about weighting based on damage scaling, so its likely off in some regard when it comes to playability. I'm about to head off for the night, so I'll update with a few more comments and maybe re-evaluating it based on that tomorrow. Thanks for pointing that out.

    I really hope I get the one that bounces CBs, if only for the visuals.
    Upvoted and sticky requested for great justice.

    Something you may or may not want to look into is Zagam's breakdown of optimal artifact trait paths here: https://docs.google.com/spreadsheets/d/1AGT2zwZbW2SUkowEqAp7Uj8XnywXtN6tUr6Uo8T03Ao/edit?usp=sharing

    He lists the trait paths that get all three golden traits as cheaply as possible.

    Also, if I'm not mistaken Roaring Blaze currently stacks. In that case, for ST you'd want to Conflagx2 immediately after refreshing Immolate as opposed to keeping one on cd and saving one for burst/movement, no?

    Edit: Ah, suppose the Roaring Blaze thing would go under Advanced Rotation when that gets added in. My bad.

    unless this was changed, this isn't a CB cast condition

    07/10/2016 01:22 AMPosted by Aldeen
    That being said, prioritising Mastery will cause your Damage to swing more compared to other stats due to the variance in the Damage that can be rewarded by Destruction's Mastery.


    'Note: A build that has high mastery will experience huge swings in damage from fight to fight based on how lucky you are. If you would rather have a more consistent build, consider avoiding Mastery in favor of other stats'

    Yeah, I vaguely recall Gahhda saying every spec would be stacking haste, but that was a few weeks ago. Not was also saying haste would be destro's best stat in the demo discussion thread.

    You're right, not sure why I included that, its been removed.

    Yeah, I vaguely recall Gahhda saying every spec would be stacking haste, but that was a few weeks ago. Also if you got your stat prio from Gaidax on MMO-Champ I'd take it with a grain of salt. I respect him as a good player, but sometimes the things he says don't make any sense. Conversely, Not was also saying haste would be destro's best stat in the demo discussion thread.
    Haste made sense to me too, but I was seeing a lot of conflicting things so decided to go with the scaling idea. I'd rather take Gahhda's word for it.

    I was thinking of including a section like this. Thanks for linking that; makes writing that a ton easier.

    Yeah, I considered including this, but I feel if I started talking about talents too much it would bloat the Basic section a bit too much, which went against the idea of it being a quick reference.
    aaaaaaaa
    I'm confused, so for Dimensional Rift it has a random effect out of 3 possible damage variations or is it controlled and picked what kind you want?

    I'm confused, so for Dimensional Rift it has a random effect out of 3 possible damage variations or is it controlled and picked what kind you want?

    Using DR will spawn one of the three rifts at random. As far as I'm aware, its completely random and nothing is in place to ensure that every three casts will have used each of the three rifts or something along those lines.

    I may not have been clear that that was random though, so thanks for pointing that out.

    Torn about stat priority, I've talked with Xyronic and he says Crit>Haste and then I see Haste>Crit here.

    Torn about stat priority, I've talked with Xyronic and he says Crit>Haste and then I see Haste>Crit here.

    It's all up in the air right now until sims actually get completed and polished. In all likelyhood, crit, haste, and mastery will probably be very close in terms of scale factors.
