Shade

The Shade is an enemy in Hollow Knight. It is the Void within the Knight which is let loose when the Knight's shell breaks.

Behaviour and Tactics When the Knight dies, a Shade appears in or before the room they died, holding all the Geo that was lost. Until it is killed, the Knight's SOUL meter is broken, limiting it to 66 charge (this does not affect the storage of SOUL in Soul Vessels).

When approaching its location, an off-key music box melody is heard that drowns out all other sounds, signalling its presence. Upon engagement, it floats in the Knight's direction and attacks by swinging its Nail when getting close and using any Spells the Knight has learned. If the Knight moves too far from the Shade's spawn point while it is pursuing them, it turns into smoke and returns to its spawn point.

As the Knight gains Spells, the Shade gains the same Spells. When below the Knight, the Shade uses a dark variant of Howling Wraiths/Abyss Shriek, when above, a dark variant of Desolate Dive/Descending Dark, and when a horizontal distance away from the Knight, it uses a dark variant of Vengeful Spirit/Shade Soul.

Hitting the Shade with the Dream Nail defeats it instantly, regardless of its remaining health.

If the Knight died to a boss, the Shade usually spawns in a safe location to be recoverable without triggering the boss battle. If the Shade is in a hard to recover position, try hitting it from a distance with Vengeful Spirit/Shade Soul to draw its attention.

If the Shade is killed, the Knight's SOUL meter is returned to normal and they regain all the Geo that was lost upon death. If the Knight dies before killing the Shade, a new Shade appears at the new death's location and the old one disappears. Killing the new Shade still fixes the SOUL meter, but all the Geo carried by the previous Shade is lost. For example, the Knight has, then dies. The Knight collects along the way and then dies before defeating the Shade that carries. A new Shade spawns on the most recent death location and the new Shade only carries.

Health The Shade's health is calculated by Nail damage multiplied by half of the Knight's hp at death rounded down. More mathematically: Nail Damage x ([max hp at death / 2]rounded down)

''Ex. having Pure Nail (21 damage) and 9 masks of health would result in: Shade hp = (21) x (9/2) Shade hp = (21) x (4) Shade hp = 84''

Location Found at the location where the Knight has most recently died. A pin of the Shade can be seen on the Map which marks its location.

Alternatively, Confessor Jiji in Dirtmouth offers a service to summon the Shade to her room in return for a Rancid Egg. This is useful if the Shade is very far away from the last checkpoint or in the middle of a hard platforming section.

Trivia
 * The Shade cannot be read by the Dream Nail.
 * Once the Void Heart Charm has been acquired, the Shade becomes passive and dies in one hit.
 * The Shade dies in one hit to environmental hazards.
 * If the Shade uses the diving spell and lands in water, the explosion does not occur and it becomes stuck in place, open to attacks.
 * Due to a bug, if the Knight dies due to an environmental hazard (spikes, etc), and their body moves to another room during the death animation, the Knight's Shade does not appear, and all Geo is lost unless the Shade is summoned by Confessor Jiji. Also, the Knight retains 100% SOUL meter even though it appears broken.
 * If the Joni's Blessing Charm was equipped when the Knight died, the Shade dies in one hit due to the Knight technically having only one Mask of health.
 * The Shade's Hunter's Journal entry is automatically filled upon acquiring the Journal.
 * In the Hollow Knight Beta, the Shade has a blue tint instead of being entirely black.
 * When defeated the Shade would explode into a cloud of ghostly-tinted Geo before being absorbed back into the Knight.
 * While this version of the Shade was active there would be no damage to the SOUL meter.
 * Team Cherry considered Dark Souls' corpse run mechanic when they were deciding on what happens after the Knight's death. The idea of the Shade developed when they finished working on the Knight's death animation, which ends with the Knight's head falling to the ground and cracking. They thought it would be interesting if players had to travel back to the place where they died and had to crack open the skull to retrieve their money. They kicked some ideas around about the skull being possessed by an enemy or suddenly fighting back, which evolved into the idea of leaving behind a ghost of the Knight's previous life that attacks players. This ghost eventually became the Shade.
