(1) I would like to share a arcane-torrent fire build, using normal %fire damage weapon
Gears requirement.
RoRG ring
5-piece Firebird's set (to get 3000% damage per second, burn the mobs until they die)
3-piece Tal-Rasha set (to get meteor, what else?)
Source with 4 apoc. A must. (either firebird or tal-rasha source. I'd suggest firebird source because it comes with %fire damage, which is awesome)
Strongarm bracers for its 25-30% additional damage
Cindercoat or magefist for %fiire damage. I choose magefist over cindercoat because you lose EHP using cindercoat.
The Burning Axe of Sankis or Devastator for %fire damage. I choose Sankis Axe because "fight through the pain" is massive in keeping your arse intact.
Basically, you can stack up to max 125% fire damage from gears
5% Tal-Rasha set
20% Amulet
20% Firebird's source
20% Magefist or Cindercoat (if you use magefist, you need to use Firebird's chest. If you use Cindercoat, you need to use Firebird's gloves)
20% SoJ
20% bracer
20% Weapon (Sankis Axe or Devastator)
You can stack up to 30% Arcane Torrent damage bonus from boots and helm, 15% each. You'll either lose CC% or VIT if you roll arcane torrent damage bonus on helm.
You can get up to 30% damage bonus on elites from SoJ & additional 15% from Bane of the Powerful (lvl 25 gem required)
Skill set up as follows,
http://us.battle.net/d3/en/calculator/wiza...ZeSb!acYcaZ(2) Using the same gears and skills, you can make another build, arcane-torrent / Hydra fire build.
You don't use fire weapon in this build.
You use Serpent's Sparker instead.
You will get 20% lesser fire damage from weapon. But who cares? You get additional hydra. You can still stack 105% max %fire damage.
If you have TNT gloves, use it. Otherwise, stick to Magefist.
Both builds are viable for T6. Both just melt T6 mobs easily.
Why fire over arcane? Firstly, you can stack higher %fire damage from gears. Secondly, fire-arcane torrent gives you damage mitigation. Thirdly, mammoth hydra.
4 apoc enough? Yes, enough. Learn to release left-click mouse. You'll be fine with 4 apoc.
What if I run out of arcane? 3000% damage per sec + mammoth hydra will do their jobs in draining dry the HP of elites while you wait for the recovery of arcane power.
If you build a hybrid build, your damage comes from from 2x mammoth Hydra (2nd build) + meteor (from Tal-Rasha's set) + arcane torrent (need I say more? Huge damage skill) + 3000% damage/sec (from Firebird's set).
Good luck and happy wizard-ing.
