Brooch of Many Sizes

While wearing this brooch, you can use an action to cast the Enlarge/Reduce spell, targeting only yourself, once per day. Additionally while under the effects of this spell, you may use a bonus action to overload the brooch causing you to change an additional size. You can't be larger than huge or smaller than tiny. When you return to your original size after overloading the brooch, you are stunned for the next turn. You can not overload the brooch again for another 7 days.
