Frost Dragon

Frost Dragon is a species of dragon with affinity for ice-type magic.

Background
Although not seen in the light novel so far, these dragons were mentioned by Ninya to be appearing in the Azerlisia Mountains. According to the New World map, frost dragons nest north-west of the Dwarf Kingdom.

Abilities
As the name suggest, this dragon possesses ice abilities. It would also seem that a Frost Dragon's body parts have magical properties as they can be used as ingredients to create magical items.
