You manage to create an aura of elemental, molten flame about yourself that empowers your next spell with the fire descriptor. This increases the damage to about half (round down). The fiery aura remains until you cast a spell with the fire descriptor, or one minute per level, whichever comes first. The aura in question feels warm to the touch.
Another spell from More Magic and Mayhem. Because the rules are open content, but not the name or the description, these have been changed to protect the innocent. 2nd Spell to use the new Spells template.
