Oiki's Pinwheel

As an action, Oiki's Pinwheel can be spun and placed on the ground. Each hostile creature within 120 feet of the pinwheel that can see it must succeed on a DC 15 Wisdom saving throw or be stunned until the pinwheel stops spinning. The pinwheel spins for 1 minute, or it spins indefinitely as long as it is within a strong wind. An affected creature can repeat the saving throw at the ends of each of its turns, ending the effect on itself on a success. Once Oiki's Pinwheel stops spinning, its magic transfers to another random pinwheel on the same plane of existence.
