Avatar of the Void

Become a living hollow. For the duration, you resist force, necrotic, psychic, thunder, and bludgeoning damage; can move through 1-inch spaces; do not need air; may hover 30 ft.; and your Void Manifestation powers deal or prevent an extra 4d10 once per turn.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
