Fire magic will blast those frosty antlers clean off, making the fight a lot easier. Just don't go slinging Blizzard spells at it, or that rack will come back!
After other Heartless were slain by Sora, Donald, and Goofy to defend Queen Elsa, a Winterhorn attempts a sneak attack from above. However, Elsa manages to destroy it with a blast of ice magic.
A Winterhorn Heartless takes in a form of a young reindeer calf. The name derives from its antlers, wrought of crystal ice, and its hooves are made of the same material.
