The Guthix staff's special attack, Claws of Guthix
The Guthix staff's special attack is Claws of Guthix. It costs 25% adrenaline and lasts for 1 minute, dealing 140%-300% ability damage. On a successful hit, this lowers the target's Defence level by 5% of the previous level. It also applies a debuff that increases the target's Hit chance values by 2. In order to unlock and use this special attack, the Divine Storm spell must be cast 100 times on the mages inside the Mage Arena (players need not do this if they have already cast the original god spells 100 times within the mage arena before the spells' removal).
This special attack is incredibly useful in high-level combat scenarios, especially when paired with debuff spells such as Vulnerability to grant the user greater accuracy and damage against bosses like Telos or Yakamaru.
When gnomes received a graphical update, so did the Guthix staff wielded by the gnomes in the Mage Arena.
After the introduction of the Evolution of Combat, the staff was not given any stats, making it equivalent to a basic staff. A hidden update fixed this, making the staff and its counterparts level 60 Magic weapons like they were before the Evolution of Combat.
