God Staves are staves that can be purchased after completion of the Mage Arena minigame. You get your first one for free, but if you lose it you will have to purchase a new one for 80,000 coins. These have +6 magic bonus and there are three different god staves. These must be held to be able to use the powerful God Spells.
The Staff of Guthix looks exactly the same as a regular staff.
The Staff of Saradomin is a white stick with a yellow and blue gem.
You will need the God Cape along with the corresponding staff to use God Spells.
