Hello Guys,
i have a problem at the End of the fight against Melchior himself. At least I think and hope it's the End of the fight.

I took him down, i don't know 3, 4 tor 5 times. Honestly i lost count but after that he allways get's his whole 75000HP back. And i start over for another Round of countless hack and slay and try to stay alive at the same time.
After i brought him to zero for the last time, he suddenly used a time stop spell and killed every member of my 4 Men Crew. I played it more then a dozen times, and it doesn't matter how long it takes 4, 5, 6 or 7 Rounds tops. He always use the spell and start running around and hit every of my Crew members until they are all dead.
It's not possible at all to move, heal, use a spell/skill, fight back, run away or to stop him.
I just lose controll over my Crew, watch them die and that's it.
i don't know, is there anything i can do? Or i'm doing wrong maybe?
An hour ago i watched a you tube Video and after they took him down at the End, he get's new HP too but after a few seconds, he suddenly stopped moving, the picture changed and he died and lost a lot of ♥♥♥♥ by the way...
It never happens after i brought him down. Just the time stop spell and then he start killing everybody.
It doesn't matter how much damage i made in my last Round after he get's his 75000HP back, just a few hundreds, 1000-10000, or 10000-29788max. He never dies and never stopped.
I played the whole Game with the same 4 characters from the beginning till now without any respec or change.
After all the time i spend for the whole game, and this fight in particular it kind of sucks and is no fun at all...
I would be grateful if someone knew a solution to this and could give me some advice or a tip on how to solve it.

Thx Guys...
