Cascading Blades

You conjure three glistening blades of transparent ice. Each blade pierces a target of your choice that you can see within range. Each blade deals 1d6 cold damage to its target. The blades all pierce their target simultaneously, and you can direct them to hit one creature or several.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the spell creates one more dart for each slot level above 1st.
