This build is for those of you interested in pure paragon XP farming. Low MP is better for this purpose. Basically, going 1 MP level higher gives about +6% XP total, but you'll end up running a lot slower than 6% usually. A good criteria is one-shotting white mobs with a multi-target skill.
Two builds currently dominate the wizard landscape, Archon and WW/CM. Both have drawbacks for optimal XP farming. WW/CM has windup time, which makes it inefficient at low MP levels, the place to be to optimally farm xp. Archon is chosen by most wizards seriously farming xp, yet standstill beam, no access to teleport/wormhole, difficult efficient scramble armor usage don't really convince me as a true endgame solution.
So, looking for an ultimate farming skill with the following properties:
- not a channeled spell. We want to run while killing mobs.
- does not prevent access to other skills, such as teleport/wormhole
- (large) area of effect spell. RoF won't cut it, obviously :)
- fire-and-forget. Micro managing position, distance and randomness is out of question
- damage ! one-shotting trash is mandatory
- spammable. Sorry hydra. and no cooldown spell.
The last candidate makes the cut: it's blizzard (I have to credit DestroyOne for his use of hydra/blizz for xp farming).
I have found that the Stark Winter (improved area) rune is a must, fewer casts and better fire-and-forget gameplay. It is quite AP intensive, and cannot really be alleviated by APoC as blizzard proc coefficient is abysmal (1% per tick with Stark Winter).
This is what I decided first: http://us.battle.net/d3/en/calculator/wizard#WlTSjQ!YWX!YYYcYZ
v2 (current) to fix AP problems: http://us.battle.net/d3/en/calculator/wizard#WlTSjQ!aWX!YYYZaZ Yeah, Power Hungry. It needs a bit of pickup radius though. Most efficient solution I've found yet.
Here is a video (sry about the audio) of a 5:45mn xp run with alkaizer's route, around 8M xp in this run. It's above 80M xp/h on average.
The vid has room for improvement. I'm still not used to the build, underusing teleport and not relying on blizzard full duration to kill packs.
Gameplay: never stop running, teleport on cooldown, single-cast-of-death entire areas with your blizzard. Storm armor takes care of isolated critters.
Healing blades get some use on elites, when you need health or when mobs block your path (barbs noclip ww is op). Reflect damage is very manageable with them.
You graze mobs as they don't instantly get killed by blizzards, so you get hit and Storm armor/scramble speed buff is almost always on. That makes it quite a risky build though.
Another drawback : most drops will be offscreen, but you should hear legendary drop sounds, if you don't play with music on.
Gearing: It's rather high-end. Mobs need to die in a single cast of Blizzard. I found it comfortable around 200K dps buffed. Good mitigation is also required (no Archon AR/armor bonus) as you will get hit a lot.
Blizzard damage does not use attack speed, so I guess 2h weapons are a possibility, though I'm reluctant to lose the dynamic of a good casting speed.
EDIT for clarity: during gameplay, you will chaincast spectral blades a lot, and teleport/wormhole. They directly benefit from IAS.
24%movespeed, helm ruby and hellfire are a given. I don't bother with Leoric signet or Cain set, though Leoric is really interesting if you can.
The Oculus source, with -4s to Teleport cooldown and +3s to blizzard duration or bonus to Spectral Blades seems a good choice.
About Frostburn gauntlets, they're very good for the build (+cold making your blades cold-based, +coldskill, pickupradius), with a single drawback: they don't boost Storm armor's lightning, which is very important to finish off single mobs.
4 pieces Tal for passive AP regeneration could be a great addition. I prefer the Power Hungry way though.
Feedback is appreciated !
