Wondrous Item, artifact
This badge (think of a smiley face button or a political button) pins onto any fabric that is worn by the user. It usually has a slogan or image (chosen by the wearer) that will change when the charge is used. (Ask me how I ACTION SURGE) changes to (I ACTION SURGED TODAY!) Or something.
It has 1 charge and when that charge is used, the wearer can use an Action Surge as a fighter does. (and yes, it does stack)
The charge is renewed at dawn.
