Fragile Strength is a Charm in Hollow Knight. It increases Nail damage by 50%.

Usefulness

Fragile Strength does not affect damage from the Crystal Heart dash or the Sharp Shadow dash.

This charm is extremely powerful, at the cost of just only one more notch, it permanently provides a similar benefit to Fury of the Fallen without the risky need to be at one health. It does stack with Fury of the Fallen, providing a 162.5% damage increase when both charms are equipped and the Knight is at one health.

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.

This charm is quite potent, although it breaks upon death. One way to make use of the charm is to only use it in situations where death is unlikely, such as exploration, in tandem with survivability-increasing charms, while avoiding its use in boss battles, except for Dream Boss battles and Godmaster Icon.png Godhome battles (as the charm will NOT break when dying to these bosses).

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

How to Acquire

Purchased from Leg Eater in the Fungal Wastes for Geo.png600. Wearing the Defender's Crest will cause Leg Eater to lower the cost to Geo.png480.

  • Shop description:
You're weak, aren't you? You should give me Geo. If you do, I'll give you this charm I made. It will make you stronger. Your enemies, and everyone else, will fear you at last...

When broken, Leg Eater can repair it for Geo.png350, or, while wearing the Defender's Crest, for Geo.png280.

  • Shop description when broken:
It's broken now, and its power is sleeping. Very sad! Give me Geo, and I'll fix it.

Once the Grimm Troupe has been summoned, Divine becomes accessible in Dirtmouth. To get the unbreakable version of Fragile Strength, 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 Geo.png15000. Once the Geo is paid, she gives the unbreakable version of Fragile Strength, Unbreakable Strength.
