Dust battlestaff

The dust battlestaff is a magical staff that requires 30 Attack and 30 Magic. When equipped the staff provides an infinite amount of air and earth runes.

The staff is dropped by superior slayer monsters and dust devils. Players can give 40,000 coins to Thormac, after the completion of the Scorpion Catcher quest, to upgrade the staff to a Mystic dust staff.

Dropping monsters
The drop rate of the dust battlestaff from a superior monster is determined by the Slayer requirement in order to slay it. The exact formula is $$\frac{1}{\frac{8}{3}*(200-\frac{(Slayer Req+55)^2}{125})}$$

An exception to this is the Choke devil, since it has the dust battlestaff on both its standard and unique drop tables, therefore being more common than the formula suggests.
