Weapon of Awe

You transform a single weapon into an awe-inspiring instrument. The weapon gains a +2 bonus on damage and attack rolls, and if the weapon scores a critical hit, the target of that critical hit becomes feared for 1 round with no saving throw and takes an additional 2d6 psychic damage. If a creature is immune to fears or has any fashion of mind shielding the fear does not take hold. A ranged weapon affected by this spell applies these effects to its ammunition.
