Sustain Fire

When this spell is cast on a non-magical fire, the fire is made to consume its fuel at only one tenth its normal rate, while giving off its full amount of light and heat; a boon in areas where firewood is scarce. A fire so affected will radiate magic is such is detected for, but is treated like a normal flame for all other purposes; it can be extinguished normally, and it does not count as a magical attack form when used against creatures that are harmed only by magical weapons.

Sustain fire can be cast on any number of fires, as long as they are all entirely within the area of effect at the time of casting. Thus, a bundle of lit torches could be created and then separated for full effect. However, if one such torch is used to light another fire, the new fire has only a normal duration. Multiple sustain fire spells cast on a single object have no additional effect, and any extra fuel added to the fire after the casting will bum at the normal rate, not at the enchanted rate. If the enchanted fire is extinguished, the spell ends, no matter how much time was left to the fuel. If the fire is relit, the remaining fuel burns at its normal rate.
