A recharging staff seems much like a normal magical staff, but has fewer charges, separates its charges by level, and has the unique ability to be recharged. As a full-round action you may focus upon the staff, expending a prepared spell slot to restore a charge of the appropriate spell level within the staff. Unlike a normal staff, a recharging staff separates the charges to each spell level. Only 1st level charges can be used for 1st level spells, and only 9th level charges may be used for 9th level spells. Likewise, only 9th level spells can recharge a 9th level charge, though you may use a 1st level or higher spell to recharge a 1st level charge in the recharging staff. The maximum number of charges a recharging staff can hold per level is show on the table below.
