It costs 12,500 points, and can only be bought from Wizard Finix's Runecrafting Shop inside Wizards' Tower near the entrance to the runespan and the Runecrafting Guild. The staff can be aligned to any spell (combat or not) on any spellbook up to level 75 (you may also re-align the staff as long as it is uncharged). You can charge all, or charge-x and discharge the staff at any time without loss of any remaining runes. The staff only holds runes, so casting the spell is like normal, using either the regular cast, or autocast method (you must be on the same spell book). This staff does not autocast on its own like a polypore staff. Staff runes may not be used in conjunction with any other spell than the one it is aligned to.
