Charge. If the reindeer moves at least 20 feet straight toward a target and then hits it with a horn attack on the same turn, the target takes an extra 9 (2d8) piercing damage. If the target is a creature, it must succeed on a DC 14 Strength saving throw or be knocked prone.

Innate Spellcasting. The unicorn’s innate spellcasting ability is Charisma (spell save DC 14). The reindeer can innately cast the following spells, requiring no components:

At will: detect evil and good, druidcraft

1/day each: calm emotions, 

Magic Weapons. The reindeer's weapon attacks are magical.

Multiattack. The reindeer makes two attacks: one with its hooves and one with its horn.
