DESCRIPTION

The targeted creature or object bursts into flames, taking 4d4 fire damage. For every two caster levels you possess, the fire lingers an additional round (to a maximum of 10 rounds at 20th level), dealing an additional 4d4 fire damage each round. A Fortitude save can be made to halve the fire damage in that round only.

A creature or object that is submersed in water stops burning and takes no damage so long as it remains submersed, but if it emerges from the water while combustion has duration remaining, the target is set alight again. Particularly flammable objects or constructs, such as those made of wood or cloth, or are covered in flammable oils, may have their hardness bypassed and take full damage from combustion (rather than the normal half), subject to GM discretion.
