The main hazard for the quest is Gravity Barriers. Stack Null Gravity Barrier monsters to move around freely. There are a number of Scorpions in the quest. Bring Poison or Bump Combos that generate a lot of hits. Every turn, you will take 8000 damage through Iwatooshi. The only way to prevent the damage is through Potions that the Angel mobs drop. Also, they will escape within 3 Turns so they should be your first priority.
