Hello! I wanted some feedback on the new spell I designed for my PF game.

----------------------------------------------------------
Enchantment Transfer

School transmutation; Level Sorcerer/Wizard 3

CASTING
Casting Time 10 Minutes
Components V, S, M (100 Gp worth of gem powder)

EFFECT
Range touch
Two magic items touched
Duration Instantaneous
Saving Throw will (harmless); Spell Resistance yes (harmless)

DESCRIPTION
Upon completion of this spell you touch one magic item and one mundane masterwork item. All enchantments of the magic item are transferred to the mundane item. Both items must be of the same type (both ranged weapons, both shields, both rings, etc...). If the recipient mundane item could not be affected by the transferred enchantment (for example, a blunt weapon being given the keen ability) the spell fails.

Thoughts? Thanks!
