Fragile Heart

Description
Increases the health of the bearer, allowing them to take more damage.

This charm is fragile, and will break if its bearer is killed.

How to Acquire
Purchased from Leg Eater in Fungal Wastes for 350. Wearing the Defender's Crest will cause the Leg Eater to lower the cost to 280.

When broken, Leg Eater can repair it for 200, or, while wearing the Defender's Crest, for 160.

Usefulness
This charm is quite potent, despite the fact that it breaks upon death. One way to make use of the charm is to only use it in situations where dying is unlikely, such as exploration, in tandem with survivability-increasing charms, while avoiding its use in boss battles, except for Dream Boss battles (as the charm will NOT break when dying in a dream). Another is to pause the game right before dying, quiting to the menu and reloading the game, which makes the charm viable even in boss battles.

It is strictly superior in effect to Lifeblood Heart - for the same charm cost, it provides two regular health points which can be healed by Focusing.

The obvious downside is that once broken, Leg Eater will only repair it for a price. Late-game, the Geo may not be much of an issue, but the trip will be.

Lastly, it should be noted that its drawback is completely negated in Steel Soul runs since the run is over upon death anyway, making Fragile Heart one of the most powerful and useful charms on a Steel Soul run.
