This spell created a barrier of heat so powerful that it could vaporize speeding bullets.
Since the spell could only be cast by powerful sorcerers and required the caster to recite the Sumerian words, Willow Rosenberg and Rupert Giles combined their abilities through an enjoining spell with Buffy Summers and Xander Harris. This Sumerian defense spell was then used in the final battle against Adam, protecting Buffy from the bullets of his machine gun.
Behind the scenes
- The Sumerian words of the incantation mean "Boil the air."
