Zamorak full helm
From Emps-World Wiki
The Zamorak full helm requires a Defence level of 40 to wear. It can only be obtained as a rare drop from Hellhounds. The Zamorak full helm provides the same stats as the Rune full helm as well as an additional Prayer bonus. There is no difference in stats between Saradomin, Zamorak or Guthix armour.
