There are a couple of problems with the zombie talent right now. The big one is that the passive healing from putting points into Necromancy, that procs whenever you deal vitality damage, hurts zombies. That might technically be working as intended but necromancy and zombies
should be complimentary. I hope Larian can change the healing from necromancy to poison if you have the zombie talent, or something along those lines. Good luck to whoever has to figure out how to actually make that work but please do!
A similar thing needs to happen when you eat body parts. Eating body parts hurts zombies because again, it's technically regular healing but come on, eating people is what zombies do. This happens with all races, not just Elves.
Finally, all credit to GodGhetto for
this suggestion. Zombies should be able to drink poison or make poisoned healing potions.
