Snake barrier

Snake barrier was a common spell used by shugenja in Kara-Tur. The spell was very rare outside Kara-Tur.

Effects
When cast, this spell created an invisible barrier that repelled all reptiles, including dragons. The barrier covered at least a 20 feet by 20 feet (6 meters by 6 meters) area, this area expanded as the shugenja grew more powerful. A reptile was able to sense the presence of the barrier despite it being invisible. Use of this spell often enraged sentient reptile-like creatures.

Components
In addition to verbal and somatic components, the spell required a material component, a piece of skin from a snake.
