Hunger of Hadar

Open a hungry demonic void in a 20-ft. radius sphere within range. The area is magical darkness and difficult terrain. Creatures that start there take 2d6 cold or necrotic damage. Creatures that end there must make a DEX save or take 2d6 acid or force damage from unseen mouths and tendrils.

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