Battlestaff

A Battlestaff is a reasonably strong weapon in terms of melee, plus having the advantage of boosting Magic. Mostly, though, it's useful in making elemental battlestaffs. By using a Charge Orb spell on an Obelisk with an uncharged orb in your inventory, you can make an elemental orb, which you can then attach to the top of the battlestaff. Then, you can take it to Thormac (if you've done Scorpion Catcher) to make a mystic battlestaff.

Battlestaff's can be bought from Zaff's in Varrock.
