The character imbues a suit of armor or a shield that the
character touches with an enhancement bonus of +1 per three
caster levels (maximum +5 at 15th level). An outfit of regular
clothing counts as a suit of armor that grants no AC bonus for
purposes of this spell.
Note: An enhancement bonus increases armors or a
shields benefit to the wearers AC. A suit of armor
cannot have more than +5 in total bonuses (even if some of its
bonus is from other than enhancement).
