The main hazard in this dungeon is Gravity Barriers. Bring Null Gravity Barrier monsters to move around the map. The Wind Machine will increase the ATK of all enemies (including the Drones). Avoid breaking him with Shield Breakers or SS that breaks Shields. They have high HP but they are breakable with Bump Combos and normal attacks. The Demons will attack your team with a map-wide Volatile Blast. They are not OHKO level (only around 20k before ATK Up), but you will be constantly at low HP. They also heal the HP of enemies so it is best to take them down first.
