Tetsu helm

The Tetsu helm is a melee helm made in the Player-owned Ports minigame. The second best non-Dungeoneering armour of its type after the Superior tetsu helm, it requires 85 Defence to wear. It can be made at 90 Smithing in the port's workshop, using 30 Plate and giving 10,000 Smithing experience. Boosts cannot be used to make this item.

The Tetsu helm lasts for 10 hours of combat before degrading to nothing. Unlike the superior version, it is tradeable and cannot be repaired on an Armour stand. Equipping the helm will cause it to instantly degrade and become untradeable.

When dying in the Wilderness, a helm will be turned into 500,000 coins which will be dropped on the ground. Otherwise, it will lose 10% of its charge upon death.
