The main hazard of this quest is Damage Walls. Multiple damage walls will come out at once, and they can do a lot of damage, so fill your team with Null Damage Wall monsters. Almost every stage has one or more Bounce Obstructors. Bring two or more Pierce Monsters to counter these mobs. If you leave the Obstructors up, they will revive the other mobs after 5 turns. The ability lock mobs are the ones with the chains wrapped around them. The ability locks can be extremely dangerous when there are multiple damage walls up, so be sure to take out these mobs first.
