If you’re just trying to kill a boss have a separate setup for the merc in the stash. I’d ditch the life leech completely. Ethereal obedience, hustle/treachery, and g face. If they’re about to die just cast lifetap.
Thats pretty much what I kind of figured out for myself as I leveled up
Just looking for a good base for an obedience. Found a eth ca. Didn't want to waste a socket quest so I rolled it... 4 sock lol. So at least the merc is doing some better dmg with insight now. And I just made an iron golem out of a ik maul for now.
Great idea for the life tap. T4t
