Mithril helm

The mithril helm is the fourth-best standard medium helmet. Being mithril, it requires 30 Defence to wear. The helmet can be smithed from one mithril bar by players with level 53 or higher in the Smithing skill. Doing so yields 50 experience. Other ways to acquire this item include buying it from Peksa's Helmet Shop in Gunnarsgrunn, buying it from Raum Urda-Stein's Armour Shop in Jatizso, or obtaining it as a monster drop.

It is rather overlooked by many players, as full helmets offer better bonuses, and it is a relatively weak metal. They rarely sell on the grand exchange, and it is recommended to alchemise them.

A mithril helm is required for one of the medium treasure trail emote clues.
