Arcfrost

An arc of frigid energy glides towards a creature within range. The target must make a Dexterity saving throw. On a failed save, roll a 1d4, the target takes that much cold damage and has it's next attack roll negated by that amount. This effect can stack.

At Higher Levels. The spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4). The debuff stays the same.
