The Dark Priestess end boss, Kridis, is massively more powerful than anything else Ive ever fought in the game. No matter how hard I try, even after 20+ deaths, I just can not beat her at all. I get that others might have had no issues with her, but I am a casual player with physical disabilites that reduces how long my hands can handle stress, I should not have such a difficult time with a campaign mission boss. Between the powerful adds, constant freezing and periods of immunity until all adds are dead, its just too much.
