The myre snelm (round) is a member's only helmet. There are no requirements to wear it. It can be obtained either by using the Crafting skill, or by trading with another player.
To make myre snelms, players need at least 15 Crafting, a Blamish myre shell (round), and a chisel. Creating a myre snelm will give the player 32.5 Crafting experience. The snelm is proven to reduce the damage taken from Giant Snails.
