There are Pierce Obstructors in this dungeon. You would want Bounce monsters to deal with them. There are a lot of Scorpions in the dungeon. You need Bump Combos that clear them like Poison Bump Combos, Shotguns or Homings. The only attack you have to worry about from Mosquito is the Short Spread after 3 Turns. It will deal a lot of damage so do not stop near her.
