You can either directly target the weapon you want to cast this spell on, or you can target a creature, affecting the creature's main hand weapon.
Notes
The Accursed Pariah's Greater Magic Weapon spell uses Transmutation rather than Enchantment for enhanced enhancement bonus, and in addition receives an additional +1 enhancement bonus, to a maximum of +15 with Legendary Spell Focus (Transmutation).
The Divine Slinger's Greater Magic Weapon spell may be cast on slings, granting them an enhancement bonus 2 greater than the normal enhancement bonus granted by Greater Magic Weapon.
This spell will auto-recast when the duration expires if the caster still has unused copies in his memory, if the caster and the recipient are in different areas the spell effects will gradually degrade until they completely dissipate.
