The Staff Mace is a Quarterstaff +2 which can transform into a mace, although when wielded it is a mace always, even for mages. This weapon has the properties of both staff and mace; it is a weapon which can be wielded in one hand and be used by anyone. This weapon is very similar to the Staff Spear +2, but there are some differences. In Baldur's Gate, this weapon is in the blunt weapons proficiency, but in BG:EE it is in the quarterstaff proficiency.
|“||This clerical weapon appears to be a normal wooden staff of the type used when trekking in the wilderness. It gives off a very faint aura of alteration magic. Upon identification of the command word, the staff takes on the attributes of a mace, which allows it to be wielded with one hand. This was designed for both priests and druids.||”|
(Baldur's Gate EE)
|“||This weapon appears to be a normal large walking staff, but it has a faint aura of alteration magic. Uttering the command word causes the staff to assume the attributes of a mace, allowing it to be welded with one hand. This was likely designed for Clerics or Druids, though that does not preclude use by others.||”|
