A 2-notch panic-button charm that raises nail damage by 75% when the Knight drops to 1 mask. Free pickup from a corpse at the start of King's Pass.
Fury of the Fallen is the panic-button charm every Hollow Knight save starts with. Per the wiki, the 2-notch charm sits on a corpse in King's Pass within the first 2 minutes of any new game; equipping it grants a +75% nail damage boost the moment the Knight drops to a single mask remaining. The boost persists for as long as the Knight stays at 1 mask, then disappears when a heal restores any mask.
According to the wiki, Fury affects only nail strikes and Nail Arts. Spells (Vengeful Spirit, Shade Soul, Howling Wraiths, Abyss Shriek, Desolate Dive, Descending Dark) are unaffected; Sharp Shadow damage is also unaffected. The +75% multiplier stacks multiplicatively with Quick Slash speed and Unbreakable Strength damage, which is why low-HP Pantheon panic windows hit harder than full-HP normal swings.
The wiki specifies a critical Pantheon edge case. Adding Lifeblood Masks AFTER dropping to 1 mask does NOT cancel the Fury state. The Knight at 1 mask with Lifeblood Heart or Lifeblood Core can build up to 6 effective masks while keeping the +75% nail damage active. This is the canonical Pantheon-of-Hallownest sustain build pivot for low-HP situations.
This guide covers the +75% mechanic, the King's Pass corpse pickup, the Fragile Strength stack to 162.5% damage, the Grubberfly's Elegy projectile pairing, the Lifeblood Pantheon trick, and the common mistakes around the 1-mask trigger.

Lifeblood Masks added after 1-mask trigger keep Fury active for the rest of the Pantheon run.Fury triggers the moment the Knight's mask counter reads 1. Per the wiki, the +75% nail damage is a multiplicative buff that applies to every nail strike (forward, up-slash, down-slash) and all three Nail Arts (Cyclone Slash, Great Slash, Dash Slash). The visual tell is a red aura around the Knight's body and a fiery effect on nail swings while Fury is active.
According to the wiki, the buff drops the instant any heal restores a mask. A single Focus heal that raises the Knight to 2 masks cancels Fury immediately; the aura disappears and damage returns to baseline. This is the canonical Fury tradeoff: sustained 1-mask combat means sustained +75% damage, but a single defensive heal flips the build off.
The wiki specifies what Fury does NOT affect. Spell damage stays at baseline; Sharp Shadow dash damage stays at 1x nail; Grubberfly's Elegy projectile damage scales with nail but is gated by full-HP, which the 1-mask Fury state by definition excludes. The only damage layer Fury raises is the direct nail-derived damage path.

Per the wiki, the 2-notch cost ties with Sharp Shadow and Soul Catcher as one of the cheapest damage-leaning charms in the game. The free pickup at game start means every save can use Fury from the first bench.
Fury sits on a small corpse on the right side of King's Pass, the tutorial cliffside the Knight enters at the start of every new save. Per the wiki, the corpse is visible from the path; striking or interacting with it releases the charm as a pickup item.
According to the wiki, the pickup is missable only in the sense that players who rush past the cliff without exploring can skip it. There is no ability gate, no Geo cost, and no enemy fight between the King's Pass spawn and the corpse; the charm is meant to be picked up within the first 1-2 minutes of every playthrough.
The wiki notes the corpse itself is a small bug husk wearing remnants of armour. The visual design parallels the Hallownest Vessel-husk theme; Fury's lore framing is the warrior's last-stand instinct, which matches the in-game trigger of fighting harder when nearly dead.
Per the wiki, Fury is the canonical first charm pickup of every Hollow Knight save. The 2-notch cost fits inside the starting 3-notch budget alongside any 1-notch utility like Wayward Compass or Stalwart Shell. New players who run Fury during Forgotten Crossroads exploration get the damage spike every time False Knight knocks them to 1 mask.
Adding Lifeblood Masks AFTER triggering Fury does NOT cancel the buff. Per the wiki, the Fury state only checks regular masks, not Lifeblood Masks. A Knight at 1 regular mask who gains 5 Lifeblood Masks via Joni's Blessing or Lifeblood Core stays in the +75% Fury state for the rest of the run.
According to the wiki, this is the canonical Pantheon-of-Hallownest sustain pivot. The Knight starts a Pantheon run with normal masks, takes damage to drop to 1 mask, then either passes a Lifeblood Cocoon room or pops Lifeblood Core charge between stages. The resulting 1-mask-plus-Lifeblood state combines Fury's damage boost with the Lifeblood buffer for safer DPS spikes.
The wiki effects block notes an asymmetry. Grubberfly's Elegy projectile fires from full HP, which Lifeblood Masks block (Lifeblood counts as "not full" for Elegy's gate). Fury operates on a different rule: it checks regular-mask count only. The two charms thus have opposite Lifeblood interactions, which players often confuse.
Fury stacks meaningfully with three damage charms. Per the wiki, Fragile or Unbreakable Strength is the canonical pairing for the highest nail spike; Quick Slash and Mark of Pride round out the panic loadout.
Strength pairingAccording to the wiki, Fury (+75%) plus Fragile Strength (+50%) stacks multiplicatively for a 162.5% damage boost on every nail strike at 1 mask. The math: 1.75 x 1.50 = 2.625 effective nail damage. On a Pure Nail (21 base), that means roughly 55 damage per strike. Notch cost: 5 (2 + 3).
Quick Slash pairingPer the wiki, Quick Slash + Fury is the panic-button DPS combo. The 54% speed boost combined with the +75% damage produces roughly 3x effective DPS at 1 mask. Notch cost: 5 (2 + 3). Adding Strength brings the trio to 8 notches for the full damage-stack at 1 mask.
Grubberfly's Elegy non-pairingThe wiki specifies an important non-stacking case. Grubberfly's Elegy projectile fires only at full HP; at 1 mask, the projectile is disabled. However, Fury still applies to the underlying nail damage even with Elegy equipped, so the combo is still functional, just not via the projectile layer.
According to the wiki, Glowing Womb Hatchlings spawned BEFORE the 1-mask state hold Fury's buff on their attacks; Hatchlings spawned AFTER do not. The asymmetry comes from the buff applying at spawn-time, not at hit-time. Players running Joni's Blessing get the strongest Fury sustain because the converted Lifeblood Masks pool never reduces the regular-mask count.
The dedicated Fury build commits to fighting at 1 mask as the default state. Per the wiki, the loadout slots Fury + Strength + Quick Slash + Mark of Pride as the damage core, plus a 1-notch filler like Grubsong for SOUL economy.
Fury of the Fallen (2 notches; +75% at 1 mask) Unbreakable Strength (3 notches; +50% nail damage) Quick Slash (3 notches; +54% nail speed)
Mark of Pride (3 notches; +25% nail reach)According to the wiki, this 11-notch loadout fits exactly without overcharming. The Knight sustains at full HP for general play; when Pantheon damage drops them to 1 mask, Fury fires and the trio multiplies into roughly 3-4x effective nail DPS for the panic window. In actual play, this build clears Pantheon-of-Hallownest Markoth and Nightmare King Grimm reliably because the damage ceiling forgives slow dodges.
Fury of the Fallen ties to the panic-build philosophy, the Lifeblood Pantheon pivot, and the canonical nail-stack. These spokes pick up the threads.
