Hero's Charm

The Hero's Charm is an item in.

Location
The Hero's Charm is obtained in Windfall Island by giving Mrs. Marie 40 Joy Pendants. The Cabana Deed must be obtained first from her after handing 20 Joy Pendants. In, the Hero's Charm is found in a Treasure Chest in the last floor of the Savage Labyrinth.

Uses
When equipped, the Hero's Charm reveals the life meter of any targeted enemy, appearing as a red bar next to the enemy. The mask also functions during boss battles, only instead with an longer life bar at the bottom of the screen. The Hero's Charm can be equipped or unequipped anytime in the Quest Status screen.

The only two bosses in the game the Hero's Charm cannot be used against are Puppet Ganon and Ganondorf, likely because the former can only be defeated with Light Arrows, which deal no set amount of damage, and the latter does not have a predetermined life energy and can only be damaged when it gets stunned enough times; it uses a "stun counter" rather than a "health counter", so anything that stuns him actually "damage" him, not any other attacks that "directly harm him" during the time of being stunned.

Trivia

 * The Hero's Charm marks the first time in the Zelda series that an enemy's life meter can be visualized. While boss fights in feature a life meter, ordinary enemies do not.
