Grubberfly's Elegy

Grubberfly's Elegy is a Charm in Hollow Knight. When at full masks, it causes Nail strikes to shoot a projectile which deals 50% Nail damage per hit.

Usefulness
This charm is useful for completing the Delicate Flower quest as it allows for fighting from a distance and detonating the explosive bubbles found in Fog Canyon.

It can be used for exploring areas and switched out for another charm when fighting bosses. However, during the fight with the Radiance, the beams of Grubberfly's Elegy can deal damage to the boss without the need to jump, which can be a viable source of damage when combined with Quick Slash. This also applies to the Flukemarm fight as the combo will make quick work of her without the need to jump in order to reach her.

The range of the projectiles is not affected by either Longnail nor Mark of Pride, though their width will be increased with the latter.

Grubberfly's Elegy can be useful for defeating Radiant difficulty Bosses since there will be no loss of the Charm's effect, as being hit results in instant death.

When used with Joni's Blessing, taking damage of any kind will halt the effects of Grubberfly's Elegy until resting on a bench, even if the health is restored by Hiveblood.

How to Acquire
Gifted by Grubfather after freeing all 46 Grubs.
