This battle is much easier by just rushing Wiegraf, since you just need to kill him to win the battle. His allies are very powerful, and I wouldn't dare to try to kill them all. Which is a shame because that mediator had a Madlemgem.
Anyway, my plan was to rush Wiegraf, and I lost. Not much to add. I made some modifications to my team after this and won on the second attempt.
