Void Tendrils

Void Tendrils are an "enemy" in the Abyss. They sit in pits of black liquid, reaching up and flail if the player character gets close. Coming into contact with it will reduce the player's HP by 1 and "reset" them before the pit as if they had been hit by a normal environmental hazard such as spikes or thorns.

Void Tendrils cannot be harmed. The player can only pass through them if they have the Shade Cloak ability.
