Swarm

Worm is a Magic spell from Fire Emblems 1,3, and 10.

Fire Emblems 1 and 3
A long range dark magic spell used in Fire Emblem 1 and 3. Can not be obtained in the game itself, but it isn't very strong. The animation doesn't have anything to do with a worm; it shows a swarm of insects attacking.
