Joostmod/Pure Nail

The Pure Nail is a Hardmode melee weapon and one of the upgrades to the Old Nail. It fires sword beams that deal half the nail's base damage, while the player is at full health.

Like its precursor, the, it can be charged up to unleash a powerful frontal "great slash" with increased reach. This attack's reach can extend even further if the user simultaneously dashes. Alternatively, the player can perform a multi-hitting "cyclone slash" spin attack while holding up or down.

Trivia
The Pure Nail and its related weapons are references to the indie game Hollow Knight. It is the final upgrade to the player character's primary weapon.

The beams may be a reference to the first game in The Legend of Zelda franchise, where when the player is at full health, their sword fires projectiles.

The beams may be a reference to a Hollow Knight charm, Grubberfly's Elegy, which has the same effect.
