Black Ice

You whisper arcane words and conjure three frozen spikes glistening in necrotic energy to impale up to three foes you can see within range. Each target must make a Dexterity saving throw, taking 3d10 necrotic damage on a failed save, or have as much on a success. Alternatively, all three spikes can converge on a single target, dealing 4d10 necrotic damage on a failed save, or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the cold damage increases by 1d10 for each slot level above 5th.
