Alice in Wonderland

Poison Absorption. Whenever Alice is subjected to poison damage, she takes no damage and regains a number of hit points equal to the poison damage dealt.

Multiattack. Alice makes two Slam attacks. If both attacks hit a Medium or smaller target, the target is grappled (escape DC 14). Alice then makes an Acid Spit attack. 

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) bludgeoning damage.

Acid Spit. Alice chooses one creature it can see within 5 feet of it. The target must succeed on a DC 11 Dexterity saving throw, or it is covered with corrosive sap and takes 5 acid damage at the start of each of its turns. Dousing the target with water reduces the acid damage by 1 point per pint or flask of water used.

Poison Spray (Recharge 4-6). Alice chooses one creature it can sense within 5 feet of it. The target must succeed on a DC 11 Constitution saving throw or be poisoned for 1 hour. While poisoned in this way, the target is unconscious. At the end of each minute, the poisoned target can repeat the saving throw, ending the effect on itself on a success.
