Fury of the Fallen

Description
Embodies the fury and heroism that comes upon those who are about to die.

When close to death, the bearer's strength will increase.

How to Acquire
Found in King's Pass, the starting cavern, behind a spike filled cavern. Look for the Geo cluster that is in the bottom right of the pit room. Use cloak to cross spikes, continue right to find the charm.

Can be reached in the beginning by slash-jumping off of the spikes, or returned to later with Mothwing Cloak or Mantis Claw.

Usefulness
Fury of the Fallen only affects Nail damage (including the strength of Nail Arts), so a build using this charm should be Nail-focused and not Spell-focused.

Since the ability requires the player to be in a near-death state, it is most useful in builds where the player tends to get damaged a lot (being a new or unskilled player) or builds designed to intentionally bring the player down to 1 Mask, such as speedrunning where the player can reliably dodge most attacks.

In a regular game, Fury of the Fallen is only useful if the player is able to avoid taking the last hit of damage for long enough to get in nail hits. Using Quick Slash and Grubberfly's Elegy to deal more damage faster or from a safer distance is recommended. Otherwise, it is more advised to use a charm like Quick Focus to bring the player back into the fight sooner.

Charm Interactions
Note: The above two charms also stack together, giving the projectile 131.25% Nail damage.
