Void Tendrils

"Fragments of void taking the shape of sharp, thrashing tendrils. The bugs of Hallownest sometimes wondered whether there were other, older, stranger Kingdoms deep below them. What strange fancies they had. That's probably why they were always so distracted and easy to kill."

Void Tendrils are enemies in Hollow Knight. They are fragments of Void shaped like tendrils which lash out at intruders to push them away or pull them under.

Behaviour and Tactics
Void Tendrils emerge from pits of black liquid, reaching up and flailing if the Knight gets close. They deal contact damage and cannot be harmed.

Location
They are only found in the Abyss, in pools of Void and in the sea of Void. The Void Tendrils' Journal entry is found within a secret area to the right of the lighthouse in the Abyss, accessed through a passage in the ceiling. The secret passage is located there.

Trivia

 * They will no longer appear after obtaining the Void Heart Charm.
 * Grimmchild and the Weaverlings spawned by Weaversong will attack the tendrils, dealing no damage.
 * When equipped with Grubsong,  Weaversong will be able to extract Soul from the tendrils, allowing for an infinite amount of Soul to be obtained.
