Crystal Shard

You create a shimmering arcane crystal shard in your palm that shoots at a creature within range. Make a ranged spell attack against the creature to assail it with the razor-sharp crystal. On a hit, the target takes 1d8 piercing damage and has their speed reduced by half until the end of their next turn.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
