Bag of swamp seeds

Inside this heavy cloth bag are 12d6 seeds. The bag weighs 1/2 pound plus 1/4 pound for each seed it contains.

If you dump the bag's contents out on the ground, they explode in a 10-foot radius, extending from the seeds. Each creature in the area, including you, must make a DC 15 Dexterity saving throw, taking 5d4 posion damage on a failed save, or half as much damage on a successful one.

If you remove a seed from the bag, plant it in dirt or sand, and then water it, it turns 60 ft of area into swampland
