The seasinger's hood is Magic tank head armour made in the player-owned port minigame. It requires 85 Defence to wear, and 90 Runecrafting to make in the port's workshop, using 30 chi and giving 10,000 Runecrafting experience.
The seasinger's hood lasts for 60,000 charges of combat before degrading to nothing - it cannot be repaired. Equipping the hood will cause it to instantly degrade and become untradeable, even if it has not been used in combat.
When dying in the Wilderness, the item will be dropped in the state it was in when the player was killed. Formerly, coins were dropped.
