Void Form. The elemental can enter a hostile creature's space and stop there. It can move through a space as narrow as 1 inch wide without squeezing.
Event Horizon. The elemental turns any area of bright light within a 60-foot radius to dim light, and any area of dim light within a 60-foot radius to darkness.

Multiattack. The elemental makes two touch attacks.
Touch. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) force damage.
Devour (Recharge 4–6). Each creature in the elemental's space must make a DC 14 Constitution saving throw. On a failure, a target takes 14 (2d12 + 2) force damage and the Void Elemental regains hit points equal to half the force damage dealt.
If the saving throw is successful, the target takes half the force damage and the Void Elemental does not regain any hit points.
