Fragile Heart

Fragile Heart is a Charm in Hollow Knight. It increases the Knight's health by two masks.

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 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. Wearing the Defender's Crest will cause Leg Eater to lower the cost to.

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

Once the Grimm Troupe has been summoned, Divine becomes accessible in Dirtmouth. To get the unbreakable version of Fragile Heart, it must be equipped before listening to her, then it must be given to her when prompted. She will eat the charm, then ask for. Once the Geo is paid, she gives the unbreakable version of Fragile Heart, Unbreakable Heart.
