Goodberry

Ten berries appear in your hand and are infused with magic for the duration. A creature can take a bonus action to eat one berry. Eating a berry restores 1 hit point and provides enough nourishment to sustain a creature for one day. Uneaten berries disappear when the effect ends.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
