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 to these bosses).

It is strictly superior in effect to Lifeblood Heart (except when using Grubberfly's Elegy) - 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 a much more useful charm on a Steel Soul run.

How to Acquire

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

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

Unbreakable Heart

Once the player has summoned the Grimm Troupe, Divine becomes accessible in Dirtmouth. To get the unbreakable version of Fragile Heart, the player must equip it then when speaking to her, give it to her when prompted. She will eat the charm, then ask for 12000‍12000. Once the Geo is paid, she gives the player the unbreakable version of the Fragile Heart charm.
