"Adds an additional hit point but lightly weakens your attack power."
The Heart charm can be a good replacement for the Smoke Bomb charm on aerial bosses such as Wally Warbles and Cala Maria. The 5% damage reduction is negligible considering the usefulness of the extra hitpoint. Because of that, it makes the fights a little longer, but is good for amateur players. It may be good to try doing this charm on Expert to gain skill at dodging the obstacles.
- This charm was once known as the "heart buddy" as seen from a gamescom video from 2015
