Tail Strike

You can attack and possibly knock a nearby target prone with your tail.

Prerequisite: Strength 16 or higher.

Benefit: When a creature you can see starts its turn within 5 feet of you, you can use its reaction to make an unarmed attack with your tail. If you hit with it, you deal blugeoning damage equal to 1d4 + your Strength modifier. If the target is Medium or smaller, it must make a Strength saving throw. The DC is equal to 8 + your proficiency bonus + your Strength modifier. On a failed save, the target is knocked prone.

Once you use this feature, you cannot use it again until you finish a short or long rest.
