You can’t clean the Flooded Mine because sometimes the AI is stuck and you can’t attack it. Happens often when in werewolf form, use Tattered skill.
I had the same issue as a Sorcerer. Used a combination of chain lightning, frost nova, and flame shield and two of the AI are stuck and I can’t attack them. Flooded Mine lvl 27.
ditto. 3 enemies in T-pose. lvl 43 Sorceress.
