Waterfowl Dance

Choose a willing creature that you can see within range. Until the spell ends, the creature has a 10 foot radius aura of razor sharp strikes.

Whenever a creature enters the aura, via it's own or the target's movement, the target may force them to make a Dexterity saving throw against your spellsave DC as a free action. On a failure, they take 4d12 magical slashing damage, half of that on a success. Additionally, the target is considered behind three-quarters cover when targeted by ranged attacks.

When the spell ends, both you and the target suffer a level of exhaustion, and the target cannot take actions until after it's next turn as a wave of exhaustion washes over them.
