Iceborn
Synergy Feat
Prerequisite
3 levels in adept, 3 levels in sorcerer, Manifestation (Blizzard)
In the depths of your heart there is a chill you have learned how to truly harness, turning your deep connection to the cold to manifest it around yourself. You gain the Ice Armor feature.
Ice Armor. When you deal cold damage with a spell of 1st-level or higher, you can spend 2 sorcery points to briefly encase yourself in form-fitting magical ice that protects you from harm without hindering you in any way. While encased in this magical ice you gain immunity to cold damage, resistance to fire damage, and resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons. The magical ice evaporates when you take damage equal to or greater than your level, or at the start of your next turn.
