Bag of Beans

Inside this heavy cloth bag are 3d4 dry beans.
If you dump the bag's contents out on the ground, they explode in a 10-foot radius, extending from the beans. Each creature in the area, including you, must make a DC 15 Dexterity saving throw, taking 5d4 fire damage on a failed save, or half as much damage on a successful one.
If you remove a bean from the bag, plant it in dirt or sand, and then water it, the bean produces an effect 1 minute later from the ground where it was planted.
