Walking Worms

Upon casting this spell you, or someone you touch, poofs into a swarm of bugs, birds, frogs, etcetera, (Specific species is up to you). Unwilling creatures will have to make a Constitution saving throw, on fail they will be turned into a swarm of your choice for four rounds. The collective memories and wisdom of the creature will be shared across all the creatures in the swarm during the spell, When back to their original form they will still retain all knowledge gained before and during the spell. The amount of creatures in the swarm depends entirely on the body mass of the target. A large creature will poof into a large swarm nd a small creature will poof into a small swarm.
