Mystic steam staff

The Mystic steam staff is the most powerful steam elemental staff. It requires level 40 Attack and level 40 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, 27,000 after completing the Seers' Village Hard tasks. This upgrade boosts the staff's level by 10.

Assuming the Seers' Village Hard tasks have been completed, each steam battlestaff upgraded into a mystic steam staff would yield a profit of coins.

The steam battlestaff was released on 28 August 2007 as part of the God Wars Dungeon update. The staff used to look no different from a staff of air except that it had a very slight blue tint to it, however, it received two updates afterwards, changing the appearance of the staff to progressively look more unique.

Since the release of Dungeoneering, the Tome of frost provides an alternative method of supplying water runes, but it cannot be used in conjunction with staves to provide a different combination of runes (including fire) due to the EoC update making staves two-handed.

With 85 Crafting, players may attach a shade skull to the Mystic steam staff, creating a Necromancer's steam staff.
