The caster creates a small (2 M radius), magical zone that can detect the passage of enemy creatures. When the field is activated, it explodes, doing 1d8 points of fire damage per caster level to all within the area of effect, to a maximum of 20d8.

• If targeted on a creature or in their immediate vicinity, the fireball explodes immediately.
