Claim island flag

The claim island flag is an item that allows the player to claim an Uncharted Island for themselves. Once the flag is planted on an island, the player can return to it at any time for three supplies. The flag is received as a reward from Boni's mini-quest, can be purchased from Boni for five chimes after her mini-quest, and can also potentially spawn on an Uncharted Island.

The player may only claim one island at a time.
