Curse of Boreas

6th-Level Transmutation

Casting Time: 1 action
Range: Self (60-foot cone)
Components: V, S
Duration: Concentration, up to 1 minute

A whisper of freezing wind wafts from your lips in a 60-foot cone. Each creature in the area must make a Charisma saving throw, taking 4d8 cold damage and being restrained on a failed save or half as much damage with no additional effect on a successful one.

A creature restrained by this spell takes 2d8 cold damage at the end of each of its turns and then must make another Charisma saving throw. It has advantage on this saving throw if it has taken any fire damage since the end of its last turn. If it successfully saves against this spell three times, the spell ends for it. If it fails its save three times, it is shrouded in ice and restrained for 10 minutes. The successes and failures don’t need to be consecutive; keep track of both until the target collects three of a kind.

Another creature can free a restrained creature in 1 minute using fire or weapons to chip away the ice.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the initial damage increases by 1d8 for each slot level above 6th.
