This dungeon is a one-time visit, so make sure that you collect all chests and bestiary listed below:
Monster Checklist:
Boss: Leviathan
Leviathan's normal attack is very annoying because it can petrify you. Moreover, its Tsunami can wipe out your party easily if you are not strong enough. Its elemental weakness is Thunder, so Thundaga and Heavenly Wrath will deal more damage than other spells.
Before leaving, open your map and check if you have 19 chests and 1 item collected.
