Rimetouched

This subclass offers sorcerers a chilling new way to aid your allies and harm your foes. The Rimetouched can tap into the icy nature of the Frostfell. Through your connection to this frigid plane, you can control the harsh weather of the arctic to protect your allies or hinder your foes. Create pockets of safety amongst a raging blizzard, unleash a torrent of ice upon your enemies, and encase yourself in diamond-hard ice. After all, the cold never bothered you.
