The bigger they are, the bigger you become!
Boots of Equal Footing
Wondrous item, rare
These boots are crafted from the skin from the skins of a gigantic bison. Once per day, when you are within 30 feet of an enemy, you may stomp both your feet, and you instantly become as large as the enemy really is treating your Strength score as the enemy’s true Strength score is. All items you are carrying increase in size with you, but still only provide the same number of uses ( a healing potion will only heal one character if drank). This change lasts for one hour or until will the change to stop. The charge on the item will refresh at dawn the next day.
