Cutting Trap

You draw an arcane rune on the ground, storing energy inside.

The rune stays in place for 8 hours and is a 5 feet circle. If any target steps on the rune, they must succeed on a Dexterity Saving Throw or take 3d8 Piercing damage , as magical blades emerge from the trap.

When you cast this spell using a Higher level spell slot, the damage increases by 1d8.
