The Great Zario O’Dario (2)
Treasure Chest 13 contains Zario O’Dario, who will battle you for the treasure inside the chest. This is hinted by the fact that the game autosaves when you approach the chest. Whether this is your first or second encounter with him, this fight will be a battle of attrition. He can deal 200 AoE explosion damage, spam Meats and Antidotes until he runs out, and can do 2 actions per turn. Keep hitting him while healing your party when needed, and he’ll eventually be defeated. He drops a Treasure Map Piece (Key Item; Give 4 to Captain Dawkins to unlock a new location to sail to) when defeated.
