Circular hide

Circular hides are a type of Crafting item that can be obtained as a drop from Dagannoths located on Waterbirth Island and within the Chaos tunnels. They can be used to create a spined helm.

Creating helm
To create a spined helm, the player must have completed The Fremennik Trials quest. The player must take a circular hide, 5,000 coins and a dagannoth hide to Sigli the Huntsman, who is located near the entrance to Rellekka.

Trivia

 * If you look closely at the icon of the circular hide, you will notice some shadows. These seem to be a Dagannoth's spikes on its back, which means that most hides dropped from Dagannoth's tend to be from its back.
