DESCRIPTION

You temper a single object to make it more resilient to damage. First, the object is repaired, as a make whole spell. After being repaired, it is then hardened and refined, increasing its hardness by 1 point per two caster levels (max 10) for the duration of the spell. While tempered in this manner, the object is impervious to decay and rusting effects, including those magical in nature such as rusting grasp. The object also loses the fragile quality, if it has it. It does not, however, protect it from direct attacks (aside from the increase in hardness).

Only one tempering effect can be in effect on a given object. If a second tempering is cast upon an object, only the stronger of the two effects remain.
