Well, if I recall right, I kept a fusioned Desco (which was twice the level than anyone else) on the bottom and used towers to get most of my team to the upper side. Then I killed who I could right there, or threw them to the pit with Desco.
Still, those freaking shamans are really resistant.
Thanks for the tip. Just in advance so I can be prepared, did you find any other levels beyond that annoying? Aside from final boss. Final bosses are always difficult. I never thought anyone can fuse with Desco. I'll do that
They kill my team in one hit with a simple blow. I had to go to the item world yet it changed nothing.
If you power level Desco, a fusion with her is going to be the most overpowered thing ever, as her third special attack gets a huge area of effect (as a plus side effect, powerleveling Desco through fusions can also give you an army of obsenely strong monsters)
As for annoying levels, there's one where everyone starts doing giant magiweapon fusions, do a ton of damage and resist a lot. Even with a few 110+ characters it was hard. The levels shouldn't get trickier than the wall one, but the enemies only get stronger.
