Void Heart

Void Heart is a Charm in Hollow Knight. It causes Siblings, Void Tendrils, and the Shade to become passive. It also unlocks 4 Endings and allows entry into the Pantheon of Hallownest.

Usefulness This charm replaces the Kingsoul Charm and cannot be unequipped. However, it no longer has Kingsoul's effects, nor does it use any Notches.

Having Void Heart unlocks new dialogue with Confessor Jiji, Steel Soul Jinn, the White Lady, Hornet, and Bardoon.

How to Acquire Found in a secret area at the bottom of the Abyss known as the Birthplace. The area's entrance only opens if the Kingsoul Charm is equipped. At the end of the area is an egg which, upon being hit with the Dream Nail, reveals a memory of the Knight involving Vessels and the Pale King. It is after traversing this memory that the Kingsoul is changed into Void Heart.

Trivia
 * It is not possible to die during the climb up the Abyss after which Void Heart is obtained. Damage can be taken after being hit by spikes, but the Knight's health never runs out.
 * The Knight also has infinite SOUL during the climb.
 * Void Heart is the only Charm that does not use up a charm notch and is also the only charm that cannot be regularly unequipped by the Knight.
 * The only time Void Heart can ever be unequipped is when using the Charm Binding in the Pantheons.
 * Void Heart is automatically equipped once obtained without the need to sit on a Bench.
 * When Void Heart is obtained, a distorted version of the normal sound for getting items and abilities is played, similar to obtaining Salubra's Blessing.
 * While the egg in the Birthplace can be hit with the Dream Nail from either the left or right side, the Dream Nail hitbox is only on the reflective part of the egg.
 * The egg stops showing a reflection of the Knight after obtaining Void Heart.
