Fragile Strength

Description
Strengthens the bearer, increasing the damage they deal to enemies with their nail.

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

How to Acquire
Purchased from Leg Eater in Fungal Wastes for 600. Wearing the Defender's Crest will cause the Leg Eater to lower the cost to 480.

When broken, Leg Eater offers to repair it for 350, or, while wearing the Defender's Crest, for  280.

Usefulness
Fragile Strength increases Nail damage by 50%. It does not affect damage from other melee sources, such as the Crystal Heart dash or the Sharp Shadow dash.

This charm is extremely powerful, at the cost of just only one more slot it permanently provides the same benefit as Fury of the Fallen without the obviously risky need to be at one health. It does stack multiplicatively with Fury of the Fallen, providing a 125% damage increase at one health when both charms are equipped and the player 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, 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.

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 Strength one of the most powerful and useful charms on a Steel Soul run.
