[Ambush] Life-based Detonate Dead Witch build- high map clear speed

Disclaimer: This is not intended to be a guide and is not written to be newbie friendly.
However, if there is more interest in this build I will consider writing an in depth guide that explains some of the mechanics and variations of this build.

Courtyard with curse immunity, half regen, and increased monster life https://www.youtube.com/watch?v=HBhPjdlOW_8&feature=youtu.be (Boss at 1:56)

My purpose in posting this build is because I've had numerous requests to do so and I wanted to showcase a map-oriented build that has quickly become my favorite build since I started playing POE. I currently have a 94 witch in ambush that has allowed me to achieve most of my goals for this 4-month league.

I started out by following an older detonate dead guide somewhere here on the forums but quickly deviated away from it and experimented with various tweaks. This build has gone through many different specs but the current one is the one that I feel has the best balance of tankiness, clear speed, and magic find. Let me say again that this build is geared towards end-game maps and not killing Atziri and uber Atziri, though it is very possible but would definitely require a respec in the passive tree as well as different links to gem skills.

Gear:
Dual wield Doryani's Catalyst for maximum DD damage
Carcass Jack for increased AOE as well as damage, life, and resists
Everything else is rare; stack as much life as possible

Feel free to ask me any questions about gear, passive tree, etc. Again, if there is interest I will consider making a longer post explaining the build. I will also add more videos when I have some free time.
