Staff of Xavier mesmerizes me. Sometimes it seems to whisper strange words, other times it's arcane fire burns in my dreams.

Something whispers to me that it is mage attribute, augmenting access to Firestaff (military riddle system of command words). These are ancient power words used by old nation to command Power, Elements, Form and Class/Alignment (Role and Position) of beings under command of Firestaff.
