Dagger Swarm

Daggers are conjured in a 3x3 around the player, including the space they occupy. Any creature other than the caster must make a DC15 Acrobatics check when entering or starting their turn in the area of effect, taking 3d4 damage on a failed roll, and half as much on a successful one. The daggers move with the player, and disappear when the spell is ended, or concentration is lost. If cast at 5th level, the 3x3 plane becomes a 3x3x3 cube. This spell can be cast 2 times per day. Tied to Swarm Dagger (not yet published), rare magic item functioning as a +1 dagger. Requires attunement
