You stomp on the ground, and fire snuffs out all around you, rippling away to nothingness faster than you can blink.

This spell functions like quench (PH 267), except as noted above. In addition, it has the following effects.

While fireward remains in effects, no magical fire effect can function inside its area. This effect is similar to that of an antimagic field, but only magical fire is suppressed. Any nonmagical fire created inside or brought into the spell's area is immediately extinguished as well.
