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

The obvious downside is that you have to return to the Leg Eater and pay Geo to have the charm repaired upon death. Late-game, the Geo may not be much of an issue, but the trip will be.

One way to make use of the charm is to only use it in situations where you are unlikely to die, such as exploration, in tandem with survivability-increasing charms like Hiveblood, while avoiding its use in boss battles. Another is to pause the game when you're about to die and quit to the menu in order to "bench-warp", which makes the charm viable even in boss battles.

In Dream Boss battles, losing the battle will NOT break the charm as technically the player character does not die. This makes Fragile Strength and Fragile Heart incredibly useful for challenging a Dream Boss.

Lastly, this charm is almost invaluable for Steel Soul runs. This is because its drawback is completely negated by the fact that when you die, your game is over anyways. This makes Fragile Strength one of the most powerful and useful charms on a Steel Soul run.
