Frostcaller

A long-ranged spellcaster that can conjure frosty energy storms to damage and chill enemies and control areas.

Frostcallers are mysterious amphibious creatures found in the deep tundra. They were recruited by Ryme for Ometa's army for their ability to control and create harsh weather conditions -- a trait that Ryme discovered when attempting to hunt for his initiates, only to have his prey defend themselves by creating localized blizzards.
