Summoning the bitter cold and biting winds of the north, you chill your targets, causing combat to be difficult for them.

Choose up to three creatures that you can see within range. The creatures must be within 6m of each other when you target them. Each creature must make a Constitution saving throw (made with Advantage if they have Resistance to Ice damage, or automatically succeeding if they are Immune to or Absorb Ice damage).

A creature that fails this save reduces their Resistance Stage to Fire and Ice damage by 1, becomes

, and any time it would make an attack or cast a spell that requires somatic (S) components, it must make a Dexterity check against your spell save DC. On a failed check, the attack automatically misses, and the spell fails but still consumes the spell slot.

At the end of each of its turns, an affected creature makes a Constitution saving throw. On a successful save, that creature is no longer affected by the spell.

At Higher Levels. When you use a spell slot of 5th level or greater to cast this spell, you can target an additional creature for every spell level above 4th.
