Tenser's Master of Arms

This spell, when bestowed upon a warrior, improves the warrior's skill with one melee weapon. A weapon with which the warrior is not proficient becomes a weapon of proficiency in the warrior's hands. A weapon of proficiency is treated as a weapon of specialization. It grants no bonus if the warrior is specialized with the weapon.
