Akmenos's Irresistible Potato

You infuse a potato that you are holding with the power of the archwizard Akmenos. While you are hold the enchanted potato, you can use your action to present the potato. All enemies that can see the potato must make a wisdom saving throw or be charmed by the potato. Alternatively you can present the potato as a bonus action, but all creatures that can see the potato must make the save. While a creature is charmed by the potato, they spend their action to admire the potato, their move action to move adjacent to the potato, and their bonus action to toss 5 gp to the potato as an offering. At the end of a charmed creatures turn they may make the saving throw again, ending the charmed effect on a success. Once a person saves against the potato, they are immune to the effects of that potato.
