Magic Resistance. Coral has advantage on saving throws against spells and other magical effects.
Multiattack. Coral makes two Hoof attacks and uses Tail Thump.
Hoof. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 12 (2d6 + 5) bludgeoning damage.
Tail Thump. Coral slams her tail down, unleashing a burst of magical force toward one creature she can see within 60 feet of her. The target must make a DC 16 Dexterity saving throw. On a failed save, the target takes 22 (4d10) force damage and has the prone condition. On a successful save, the target takes half as much damage only. If this damage reduces the target to 0 hit points, the target dies, and its body is reduced to fine dust.
Bubbles of Whimsy (2/Day). Coral produces a stream of magical bubbles from her horn. These bubbles float toward a creature Coral can see within 60 feet of herself. Roll a d6 to determine the bubbles' effect:
Gift of Speech (1/Day). Coral targets one Beast she can see within 10 feet of herself. The target gains the ability to understand and speak Common or Sylvan (Coral's choice) for 10 minutes.
