The Captain's Hat is an item dropped by Rupee Larso after defeating him in Maramba. The Captain's Hat can only be worn by Vyse. It grants Vyse +80 attack power, an extraordinarily high stat boost that remains relevant throughout the game.
The Captain's Hat is dropped by Rupee Larso, a bounty fight encountered on the docks in Maramba. Rupee Larso can be fought any time after the player has defeated Recumen and claimed the Red Moon Crystal; it is recommended that players complete this fight as early as possible to take full advantage of the Captain Hat's damage boost.
