Bag of Beans

From Dungeon Master's Guide, page 152. Found on Magic Item Table C.

Description
''Wondrous item, rare. 0.5 lbs.''

Inside this heavy cloth bag are 3d4 dry beans. The bag weighs 1/2 pound plus 1/4 pound for each bean it contains.

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. The fire ignites flammable objects in the area that aren't being worn or carried.

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. The DM can choose an effect from the following table, determine it randomly, or create an effect.
