Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks How do I finish infiltrating the immaculates

There is no way to kill the death knights in the mine. You need to finish the mines to get the death knight bane spell, but once you finish the mines they are blocked off permanently. Just forget the mines and move on.

BTW, There are plenty of death knights to kill in the Phantom Forest.
