Blann se ofginn
Blann se ofginn is a third level evocation spell cast upon the self with a one-minute duration.
Within the protocols used by the police and military, blann se ofginn ranks among other non-injurous defensive spells. Once cast, a layer surrounds the body of the castor and if anything strikes it, the kinetic energy is instantly converted into thermal energy. Depending on how much energy is converted will result in a slight heating of the air or a bright flash which can be stunning.
You may have heard anecdotal stories about a sky diver who’s parachute failed to open and used blann se ofginn to save his life. While this sounds plausible, the physics just don’t work. The spell would certainly have saved him from impacting the ground but the compression from suddenly decelerating would have been catastrophic.
The spell is often used to protect against sudden collisions if one has the presence of mind to use it such as an automobile collision or falling debris.
