Hello, I couldnt create an account on https://report.nostalrius.org/ for some reason, so i decided to post this here instead.
There is a quest in felwood called "A Final blow" Link below" Where you is supposed to kill 3 NPC´s in a cave. One of the NPC´s named "Salia" has Mind Control as a spell wich is instantcast and everytime you engage her she will cast it and reset the fight, she is not supposed to cast that spell unless there are more than one player fighting her and her MC has n/a cooldown so she will just keep MCing you over and over. This was very difficult to do solo, the only way i found to kill her was to resist her mindcontroll and then you have 20s to kill her untill she casts it again. Her health is Health: 3,300 so i had problems doing this aswell but atlast i managed to kill her. I just found this very annoying because other NPC´s started respawning around me and it was a hard time down there.
