Caltrops!

You conjure and toss a handful of arcane caltrops, that cover a 10-by-10-foot area within range. The caltrops last for one minute, and any creature that moves more than 5 feet on their turn through the caltrops must succeed on a Dexterity saving throw or suffer 3d4 damage and fall prone.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you may either increase the damage of the caltrops by 2d4 for each slot level above 2nd, or increase the area by 5 feet on each side for every two slot levels above 2nd.
