[3.9] Metamorph N1koee's Dual Voidbattery Electric Shatter's 2 screens 1 spell [Videos]

How do you survive? I'm trying out the build and blasting through packs, but every once in a while on red maps I just accidentally take an attack and go from 100 -> 0 instantly, and this is with close to 7k EHP. It's even worse on juiced maps because some ranged mobs can 1 shot you from offscreen before you even get into storm brand/call range.

Same for bosses, I feel like you need to have enough DPS to burst them instantly because you are pretty much dead if you run into any attack at all.

What do you use instead of Void Batteries until you can get them? Just a rare wand with crit, spell damage, cast speed etc?

Also, what do you think about usind Doryanis Catalyst or Cerberus Limb + Light of Lunaris for leech when you aren't using an assassin mark rings?
