The Star Rank (or Prf Rank) is used to denote a weapon that can only be used by certain characters (usually Lords) in the weapon rank system. For a list of these weapons see List of Star Rank weapons.

Usually, these weapons will have many or infinite uses, in-game, as there is often only one copy of them per game. However, star-ranked staves still typically have few uses before breaking. Also, they might say that they have a required weapon rank, however, it is usually E, and, being the lowest rank possible, it doesn't make any impact on the usage availability. However, certain Prf weapons have a high weapon rank and can be used by multiple people. (particularly the Aum staff in Fire Emblem Shadow Dragon).
