Cobra Lash has been a favorite skill of mine for a long time. Badge of the Brotherhood has been a favorite item of mine for a long time. It was time to combine them.
I have made many iterations of this build in PoB over the last few leagues, but I never got it quite right. Finally this league I have managed to make something that is fast (300+ ms), tanky as hell (150k EHP), great clear (HoI explosions + chaining) and smooth to play! The build gets tanky in a few ways. We layer evasion with some block and avoidance from elusive to get to an absurdly low chance to be hit by attacks.
95% evade
41% block
56% avoid
= 1.2% chance to be hit by an incoming attack
For spell hits? We avoid 56% of those too, and then use our 100% spell suppression to reduce incoming damage by 66%. Then we have a 50% chance to recharge our ES on spell hit, and if we have a ghost shroud, which we always do, because we dont get hit, we fully heal our ES instantly. During soul gain prevention, we get an extra 12% chance to avoid elemental damage which isn't even factored in here. This build regularly tanks boss slams and beams. (In the video footage you'll see me tank, not avoid, the eater of worlds slam)
Offensively, because we are scaling Elusive to the moon, we easily get over 1000% crit multiplier. This experiment ended up being better than expected at nearly everything I put it up against. I hope you enjoy!
