Cry Bunny

Legendary Resistance (2/Day). If the Cry Bunny fails a saving throw, it can choose to succeed instead.

Critical Pain. When the Cry Bunny takes its first critical hit, it immediately drops to half hit points and one of its heads dies. 

Telepathy. The Cry Bunny and the target can instantaneously share words, images, sounds, and other sensory messages with one another through a telepathic link, and the target recognizes the Cry Bunny as the creature it is communicating with. The Cry Bunny can communicate only in the Elvish and Sylvan languages to understand the meaning of your words and take in the scope of any sensory messages you send back to it.

Soul Glare. The Cry Bunny glares into the creature's soul with its pure, red eyes, and drains its life force. The creature makes a Wisdom saving throw DC of 18, on a failed save the creature takes 4d12 damage and the Cry Bunny gains half that much hit points. On a success, the creature and the Cry Bunny each take 2d12 damage.

Multiattack. The Cry Bunny can use both of its heads to make two attacks with its bite.

Vampiric Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., Hit: 10 (3d6 + 4) piercing damage. The target’s hit points are reduced by an amount equal to the damage taken, and the Cry Bunny regains hit points equal to that amount.

Jump. The Cry Bunny jumps up 10 feet in the air, and lands with great force. Each creature within a 10 foot radius of the Cry Bunny must make a Dexterity saving throw DC of 18. On a failed save, a creature takes 5d6 bludgeoning damage and is knocked prone. If the ground in that area is loose earth or stone, it becomes difficult terrain until cleared, with each 5-foot-diameter portion requiring at least 1 minute to clear by hand.

Stunning Scream. The Cry Bunny makes a horrific scream. Each creature within 30 feet in front of the Cry Bunny makes a Constitution saving throw DC of 18. On a failed save, a creature takes 2d6 psychic damage and is stunned for 1 round. On a success, a creature takes half damage and are not stunned.
