Ripe Feyberry
This berry from a Feyberry bush retains its magic for 10 (2d6+3) days after being picked. These sweet and quite tasty berries are spherical, approximately 1 inch across, and their blue-greyish surface shimmers in various colors. If you consume the berry (as if drinking a potion), you trigger a Wild Magic surge. Each berry also restores 1 hp and contains enough nourishment to sustain a creature for a day.
