By touching a wand or staff that has at least 1 charge, you imbue it with 1 temporary charge per five caster levels. These charges work like temporary hit points: When a character uses the item, deduct the charges spent from the temporary charges first. When the power surge expires, any remaining temporary charges are lost.
