Aum Staff

The Aum Staff (called the Olm Staff in the Japanese version) is a powerful staff that can resurrect the dead. It appears in Fire Emblem: Ankoku Ryū to Hikari no Tsurugi and its sequel and remakes and can only be used on the final chapter, but with a single use before it breaks, its a staff to be used wisely. The character comes back with the same stats as they had when killed, but at full HP and free of status conditions. It originally could be only used by Elice, although in Shadow Dragon it can be used by Maria, Minerva and Shiida (with the last two reclassed into a Cleric, Bishop or Sage).

It cannot be used to bring back the character which was used as a decoy in the Prologue chapters.

Etymology
It is named for a heavily religious symbol in Asia.
