Reserve

Also known as Fortify

The Reserve Staff restores HP to surrounding allied units. The range of the staff is determined by the wielder's Magic. Reserve was the name given to the staff in fan translations of Seisen no Keifu. Reserve is one of the most powerful healing staves in the Fire Emblem series, and should only be used when absolutely needed. In some games, such as Shadow Dragon, Reserve restores HP to all allies, no matter where they are on the map.
