Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Where to go now?

I completed all main quests in Luculla forest? The only place I have not venture in, is some place where all monsters have "void armor" Can't kill them.

Should I go to Phantom forest then now? or Am I suppose to do something else?

You are supposed to simply get past those monsters and kill whatever gives them the Void Aura with a Tenebrium weapon.
