Taor of the Black Scorch
I made a Black Scorch caster that deals ridiculous damage and provides allies with up to +61% physical resistance (Aura of Conviction, Aspect of the Guardian, Prismatic Aura, Empowered Rituals).
The build primarily uses Oblivion relic and Sigils of Consumption to deal damage, with a range of other dot procs. The highest crit with Oblivion so far is about 170k, and casts 4-5times a second. Highest crit from Sigil of Consumption is about 60k, you can have three of them up at once. Plenty of other damage procs.
Here’s a quick demo vid of the build in 150-160 crucible (~4mins) . Buffs, no banners. As you can see, it really isn’t a problem due to the high physical resistance, damage absorption and healing abilities of the build.
