Glintstone Staffs are catalysts used to cast sorceries. They scale with Intelligence and allow access to a wide range of powerful spells. Depending on the spells that you find on the your Staff, their versatility, raw power and ability to inflict high both area and single target damage can be unmatched, though some sorceries can be very FP-hungry. Staffs are ncessary for builds that focus around casting spells.
