Void Heart

Usefulness
Allows access to the second and third endings of the game. Once the player has acquired the Void Heart, they cannot access the first ending without starting a new game.

Makes player's Shade and Siblings non-hostile to the player and deal no contact damage. They can always be destroyed in one hit. Siblings will return back into the ground after a short period. Void Tendrils will no longer appear, and the player can safely swim in any pools that previously had Void Tendrils in them.

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

While worn, this charm unlocks new dialogue with Confessor Jiji, Steel Soul Jinn, The White Lady, Hornet, and Bardoon.

How to Acquire
Found in the Birthplace - its entrance is located at the bottom of the Abyss, which will only open if the Kingsoul charm is equipped. At the end of the area is an egg which, upon being hit with the Awoken Dream Nail, reveals a scene from the past involving vessels and the Pale King.
