Aspect Icons

Wondrous item, rarity by icon, unknown (requires attunement)

An aspect icon is a beast statuette small enough to fit in a pocket. While you carry the icon, you can use an action to use the icon to gain the aspect of the depicted beast. You gain abilities specific to the aspect for a certain duration, and once used, the icon can’t be used again until a certain amount of time has passed, as specified in the icon’s description.
