Goddess Staff

The Ashera Staff (simply Goddess Staff in the Japanese version) is obtained in Fire Emblem:Path of Radiance Chapter 22 by not killing any enemy priests or Bishops. It has only three uses, so, despite the fact it can heal everyone to full health and restore everyone's condition back to normal (except for death), use it carefully. You can also get the staff in Fire Emblem:Radiant Dawn if you recruit Lehran. It has the same effect as the earlier Saint's and Latona Staves.
