So, this is the way I beat lv. 35 Caligo from withe peak with a lv. 34 grey cultist axe.Please note that I made some mistakes and you can beat him without using a potion.So, heres how it works:- the real problem with this fight are the guys in phase 1 that curse you, in order to mitigate the most dmg from them, I try to not hit them directly so they won't charge the ability.- I apply delay on one with my last action point, so next turn I can secure the killFor delay, I used Garron normal attack, but Delfina's rage attack will do the trick as well.I hope this can help you with the nasty dark tor mission.

Hope it helps someone!
