Light Transformation:  When a Volatile is exposed to daylight (either real or magical) they transform in to a Ghoul.  This transformation is painful and leaves the creature exposed.  This transformation takes 1 round, during which attacks against the creature have advantage.

Regenerative Transformation: Immediately following transformation, the creature restores all its hit points.

Multiattack. The Volatile makes three Claw attacks. It can use its Bite in place of one Claw attack.

Nimble Escape. The Volatile can take the Disengage or Hide action as a bonus action on each of its turns.

Dimensional Movement. The Volatile has the ability to move along vertical surfaces on it's turn without falling during the move.

Rapid Movement. The Volatile can jump as if it was permanently affected non-magically by the jump spell.  Carrying another medium or smaller creature does not affect the distance that the Volatile can move in this manner.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: 20 (3d8 + 7) piercing damage.
Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 17 (3d6 + 7) slashing damage. If the target is a creature other than an elf or undead, it must succeed on a DC 16 Constitution saving throw or be paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
