Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Never using the Undead until Zombie modded out

Just pair undead with necro.. use necromancy to gain life from doing damage and sustain yourself on that and poison not to mention there is a special artifact that converts healing potions into poison potions for undead and that undead have abilities other races do not (unlimited lockpicking/walking thru the deathfog or whatever)

there is no other way past the deathfog other than being undead... so if you dont have an undead with you things will be locked away from you behind this fog...

but there are plenty of ways for undead to sustain themselves if you use the right skills.
