Yeah, have you healeer and tank jump down and pull from the bottom, the dps from the top and meet up at the top pillar near the stairs to line of sight archers so you can group them all up.
Once you get the walls, have your healer stay in the middle to manipulate the walls while you do the mobs.
You will do this on all floors, including the spooky floors when you get there.
If you have wind knights / sky specifically in your group be prepaired to reset because they knock them up in the air and lock them in the air so no one can kill them...
