Making battlestaves. Working through tasks from Varrock Diary can be quite lucrative as each of challenges it offers allows players to buy more and greater battlestaves through NPC Zaff. In the event of completing Elite Diary in Varrock, you can purchase as much as 120 battlestaves worth 7000 gold coins each. The only issue is that all have to be bought simultaneously. The staves you'd like to craft can be made from Air Battlestaff and Fire Battlestaff.
