MajorAsshole's Leech Incinerate (6-10.3k Tooltip / 100-150k DPS) using Apep's and Cherrubim's.

Did a quick and dirty Atziri run and exported it though Twitch so the quality is kinda horrible but at least it's something to see how it plays. (I'm not focused at all and play kinda poorly as well.)

Much better quality VoD:

My defenses screenshot:



On top of this I also run a level 20 Arctic Armor and a Cast when Damage Taken(7) setup with Enduring Cry(9), Immortal Call(8) and Increased Duration(20).

The build is based around using these items, none of them are required for the build to function but Rathpith and Rainbowstride is my chosen way to acquire spell block. Apep's adds mountains of DPS and synergizes with Chrrubim's that in turn synergizes with using Life Leech. Rumi's is used to cap block and spell block in high damage situations while providing armor.



The rest of my gear is focused on getting the resists required and as much life, mana regen, armor as possible. Any cast speed or spell damage on gear is purely a bonus.



These are the flasks I use and each roll is highly recommended with the Quicksilver being optional.



Still adding quality to some gems and trying to aquire level 21 added chaos/cold. Only really required gem to quality though is Incinerate it self as you will need the projectile speed.

5/6L: Incinerate - GMP/LMP - Spell Echo - Added Chaos - Life Leech (- Added Cold)
4L: CwDT(7) - Enduring Cry(9) - Immortal Call(8) - Increased Duration(20)
3L: Clarity - Discipline - Reduced Mana
3L: Herald of Ice - Empower - Reduced Mana
2L: Vaal Haste - Increased Duration
Other: Arctic Armor, Blood Rage, Smoke Mine, Elemental Weakness, Bone offering (To clear corpses).

GMP vs LMP:
This one is mostly down to personal preference, I go with GMP in most cases, but I'd recommend leveling both up. GMP will work best in maps as ranged monsters tend to spread out and with GMP you generally cover most if not all of them in one go. LMP will be better in single target situations where you can't be right up in the targets face. Either way there is no right and wrong but down to how you play the game and feel works best.

Why added cold and not faster casting?:
For a few reasons. Mana is hard to sustain as is and the build has more than enough cast speed. Green is just easier to roll as the 6th socket. Most of all though it offers great versatility as you can use Mana Leech, Blind, Culling Strike, Faster Projectiles and added cold all depending on your needs.

Blood Rage?:
With enough chaos resistance it's free DPS so why not...

Kill all in all difficulties.

It's not wrong to take the life from Oak in normal but as the build requires a lot of points I feel it's more beneficial to have the passive early on with the option to go back and change it later, when 20 regrets isn't a big deal, if necessary. For the same reason I skip the 4% cast speed, it only offers 1% over a passive and for pure min/maxing it can be changed at 95+.

This is at 95, due to mana issues I currently have 2 points in 'Soul Siphon' (Shadow) and 1 point in 3% reduced mana (Templar) that I'm looking to move in a level or two and take the whole 'Sovereignty' wheel. There are other options as well that I might try, other than those 3 points it's the most optimal version. The cast speed in Shadow is the first place to cut points if you need to compromise.

Grab Freezing Pulse and Ice Nova until you get LMP and then start incinerating, pick up EB as soon as you got enough ES on your gear that it makes a difference or when you can use Discipline. If you get a Cybil's for leveling forget about the Life Leech gem until you go Apep's, if not use it as soon as you can as it's a great survivability addition.







After this point you fill up with the missing block/mana regen node and spell damage/cast speed depending on what you feel is needed and you can sustain. You also have to respec out of 1 node once you got the second path from Witch start done.

Blood Magic:
Is totally doable as your auras are used for mana regen anyway, you do lose AA as defense and Heral of Ice for damage, but other than that it's no problems to run it.

Half-regen:
Is doable if you have a 6L and can swap in Mana Leech, again you lose AA for defense though. (It is possible to run even without a 6L by swapping Life Leech for Blood Magic and equipping a Cybil's Paw, it's not recommended and should only be done if you really have to run the map)

No-regen:
I generally avoid this one even if it's theoretically possible to run it with a 6L and Mana Leech.
