Magic Rune

Runes are Destruction type spells that are cast on the ground and act as a trap when walked over. There are three types of runes: Fire (red), Frost (white) and Shock (purple). When cast, the spell take about a second to charge up, then it can be "thrown" on either the ground or a wall, creating a circle with magic symbols. They can be shot at with a projectile spell of their respective element to manually trigger them. The Destruction perk, "Rune Master", allows the caster to throw runes farther.
