Blender Tattoo

Alter: As an action, you can speak the tattoo’s command word to cause the tattoo to separate from your skin as small, sharp, inky blades. The blades immediately begin to fly haphazardly in a magical twister that occupies a 30-foot-tall, 20-foot-radius cylinder centered on you. The area within the twister becomes difficult terrain for the duration. Each creature inside the twister (other than you) must make on a DC 17 Strength saving throw or become restrained while it remains in the cylinder. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Each creature that starts its turn in the area (other than you) must make a DC 17 Strength saving throw. On a failure, a creature takes slashing damage equal to five times the number of Small or larger creatures hostile to you within the area, up to a maximum of 50 slashing damage. A creature takes half as much damage on a successful saving throw

The twister dissipates after 10 minutes or if you use a bonus action to dismiss it, ending the effect. Once used, the tattoo can’t be used again until the next dawn.

Produced by a special needle, this magic tattoo represents a pair of fabled blades.

A sadistic tattooist once managed to trap a rare insect known for viciously devouring vast swathes of its prey. She spent the next few days observing its behavior, all in an effort to recreate the insect’s perplexing pattern of movement and attack. She then applied this research to a new tattoo she had been developing. The results were unbelievable. The new data made the tattoo’s assault almost impossible to avoid, inflicting tremendous pain before a creature could respond or retreat.
