The sword creaks as if under pressure, but when you are done casting, it is stronger than ever before.

This spell increases the hardness of materials. For every two caster levels, increase by 1 the hardness of the material targeted by the spell. This hardness increase improves only the material’s resistance to damage. Nothing else is modified by the improvement.

The hardening spell does not in any way affect resistance to other forms of transformation.

If cast upon a metal or mineral, the spell’s maximum volume is reduced to 10 cubic feet.

Augment: For every additional spell point you spend, you can target an additional 10 cubic feet of material, or 1 additional cubic foot of metal or mineral.
