The HGH Build centers around simultaneous stacking of several damage multipliers to "juice up" your DPS well beyond your current gear level. It's like shooting up your monk with 'roids. His head will get bigger and his wang will get smaller, but he'll also pwn more face.
Here are the cornerstone skills that make an "HGH Build":
Deadly Reach – Foresight
Second Primary Attack of Choice
Blinding Flash – Faith in the Light
Breath of Heaven – Blazing Wrath
Mantra of Conviction – Overawe
Here are examples of both a 2H version and DW version of HGH builds:
Two-Handed – http://us.battle.net/d3/en/calculator/monk#bUXSYk!UgX!cZbZca
Dual Wield – http://us.battle.net/d3/en/calculator/monk#baXSYk!UgX!cabcca
With a 2H weapon, I could see some players substituting in Wave of Light, possibly for Blinding Flash. For Dual Wielding, I prefer the proc-rate of FoT–Thunderclap over the Attack Speed bonus from WotHF–Blazing Fists, because I use the Cyclone rune for Sweeping Wind. If you don't use Cyclone, then Blazing Fists might be a better choice for you.
One of the hidden gems of this build is the epic situational usefulness of Deadly Reach. Even though FoT is my first choice when attacking, Deadly Reach gives me the ability to get in hits from a distance when I'm in a pinch (and don't want to teleport to the target), and it frequently saves my butt.
+15% Damage: Breath of Heaven – Blazing Wrath
+16% Damage: Combination Strike (with two primary attacks)
+18% Damage: Deadly Reach – Foresight
+30% Damage: Blinding Flash – Faith in the Light*
+48% Damage: Mantra of Conviction – Overawe
(*affects weapon damage)
Using my monk ( http://us.battle.net/d3/en/profile/Hades-1850/hero/5424043 ) as an example, here's how this all stacks up:
DPS – Unbuffed: 219.9k
DPS – Blazing Wrath: 252.9k
DPS – Blazing Wrath + Foresight: 292.4k
DPS – Blazing Wrath + Foresight + Combo Strike: 327.6k
DPS – Blazing Wrath + Foresight + Combo Strike + Overawe: 484.8k*
DPS – Blazing Wrath + Foresight + Combo Strike + Overawe + Faith in the Light: 881k*
As with any build, there are benefits and drawbacks. That said, this is my favorite monk build, and I wanted to share it with anyone who was not familiar. Please use the thread to discuss your likes and dislikes, as well as to share any effective variations of the build you may be using. Naturally, I will try to answer any questions posted.
Have an amazing day. =).
