Aesilra the Lost Fey

Multiattack. Aesilra the Lost Fey can make five attacks: one with its Hooves, two with its Ram, one with its Trample, and one with either its Poison spray or Bite.

Hooves. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 23 (5d4 + 7) bludgeoning damage.

Bite. Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 14 (7d8 + 7) piercing damage, and the target must make a DC 19 Constitution saving throw, taking 10 (7d12) poison damage on a failed save, or half as much damage on a successful one.

Ram. Melee Weapon Attack: +15 to hit, reach 10 ft., one target. Hit: 21 (7d4 + 14) bludgeoning damage plus 21 (7d6) force damage.

Trample. If the Aesilra moves at least 20 feet straight toward a target and then hits it with a ram attack on the same turn, the target takes an extra 14 (7d4) bludgeoning damage. If the target is a creature, it must succeed on a DC 19 Strength saving throw or be knocked prone.

Poison Spray (Cantrip). Aesilra bares its hidden viper-like fangs toward a creature it can see within 10 feet of it and projects an acidic spray from its hidden fangs. The creature must succeed on a DC 19 Constitution saving throw or take 24 (4d12) poison damage

Hooves. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 23 (5d4 + 7) bludgeoning damage.

Vampiric nature (Costs 2 Actions). Aesilra can sap the life force of those around it. Using its found power from the dragons merged with its own, Aesilra can heal itself by draining the life energy from any living thing around it, be it plant life or living creatures. 

Casting requirement: must be within 50 feet of plant life or any living creatures. 

Aesilra heals 1d12 for every living creature(dealing equal damage to the target) and 1 d6 for every tree, and finally 1d4 for all foliage shrubs and smaller.
