Item Master (Su)

At 10th level, a Pathfinder savant can spend an hour focusing his energies on a single non-charged magic item that requires an action to activate. At the end of this hour, that item becomes attuned to the Pathfinder savant, and from that point on, that specific item can use the Pathfinder savant’s caster level to resolve its effects rather than the item’s caster level. A Pathfinder savant can change which item is attuned to him by repeating the attunement ritual, but he loses attunement to the previous item. A Pathfinder savant can have only one item attuned to him at a time.
