Shade Soul

Shade Soul is a Spell in Hollow Knight. It is the upgrade to Vengeful Spirit. Using it conjures a shadow that flies forward and damages enemies.

Function Press FOCUS/CAST or QUICK CAST without holding UP or DOWN to launch a projectile that passes through enemies and deals damage. The projectile now penetrates all objects in its path including walls and invulnerable parts of enemies, such as a shield or shell, but will not damage a fully protected enemy.

Modifiers
 * Flukenest turns the Shade Soul into a horde of black baby flukes that bounce around dealing damage.
 * When Flukenest is combined with Defender's Crest, it launches a single large fluke that explodes into a damage-dealing cloud of gas.
 * Shaman Stone increases the width of the projectile and increases the damage dealt by 33%.
 * Spell Twister lowers the SOUL cost to cast Shade Soul to 24 SOUL.

Damage Values

How to Acquire Requires purchasing the Elegant Key from Sly in Dirtmouth after obtaining the Shopkeeper's Key.

Trivia
 * There is an unused version of Shade Soul that consists of a mixture between a black Shade Soul and a white Vengeful Spirit much like how Abyss Shriek combines black souls with white Howling Wraiths.
 * Shade Soul is obtained from a snail shaman linked to some kind of machine.
