Shaman Stone

Shaman Stone is a Charm in Hollow Knight. It increases the damage of Spells and the size of Vengeful Spirit/Shade Soul.

Usefulness

Since it increases Spell damage by 33-51% depending on the Spell, it is incredibly powerful, as it can be used to one-shot many enemies from safe ranges, or to deal more Spell damage to bosses.

Shaman Stone is incredibly useful for speedrunning, not only because of the damage boost it gives to Spells, but also because of how fast and easy it is to acquire compared to other damage sources like Fragile Strength, Quick Slash, or Pale Ore.
