The targeted weapon becomes brittle, reducing its hardness by 5 for the duration of the spell, thereby increasing the effectiveness of sunder attempts against the weapon. In addition, rolling a 1 on an attack with the targeted weapon causes it to take damage equivalent to the amount it would have dealt on a successful hit.
