The mystic steam staff is the most powerful steam elemental staff. It requires 40 Attack and Magic to wield. It provides an unlimited amount of water and fire runes. To create one, a player must take a Steam battlestaff to Thormac after completing the Scorpion Catcher quest, along with 40,000 coins. That gives it additional 12 crush attack points, and 15 strength points.

Players can use a steam staff upgrade kit, obtained from the Bounty Hunter Store, to cosmetically enhance their Mystic Steam Staff, creating a mystic steam staff (or). This only alters its appearance, and it becomes untradeable. It can be reverted, but the kit will not be retained.
