Fragile Strength

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

Usefulness
Fragile Strength does not affect damage from Nail Arts or the Sharp Shadow, Dreamshield, and Thorns of Agony Charms.

It is an extremely powerful Charm. It permanently provides a similar benefit to Fury of the Fallen without needing to be at one Mask, costing only one more Notch. The combination of both Fury of the Fallen and Fragile Strength provides a ~170.6% damage increase when the Knight is at one Mask.

The downside is that once broken, Leg Eater only repairs it for a price. In the late-game, the cost may not be much of an issue, but the trip to Leg Eater might be. Dreamgate can be used to reach Leg Eater more easily.

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, or in tandem with survivability-increasing Charms, while also avoiding its use in boss battles, except for Dream Boss battles and Godhome battles (as the Charm does not break when dying to these bosses).

Lastly, 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 in a Steel Soul run.

How to Acquire
