Your magic is born from the merciless cold of primordial winters and the frozen expanse known as the Frostfell. Whether your bloodline traces back to the ancient Jötnar or to planar frost spirits that survived the world's earliest ice ages, your power manifests as brutal glacial magic.

Coldblooded Sorcerers do not merely cast frost spells, they bring the Ice Age with them. Their footsteps freeze the battlefield, their magic reshapes terrain into killing grounds, and their bodies endure the brutal cold that would destroy lesser beings. Unlike most sorcerers, Coldblooded wield both magic and steel, fighting like hunters of the frozen wilds.
