The Superior tetsu body is a melee platebody made in the Player-Owned Ports minigame. It is the best non-Dungeoneering armour of its type, and requires 85 Defence and Constitution to wear. It can be made at 90 Smithing (non-boostable) in the port's workshop, using 100 Plate and giving 30,000 Smithing experience. Superior tetsu bodies do not stack in a player's bank, not even if they have the same charge.
The Superior tetsu body lasts for 12 hours in combat before degrading. It can be repaired at a player-owned housearmour stand, costing 1,200,000 coins at 99 Smithing.
Upon death, this item will appear under your gravestone and if killed in wilderness it will turn into 1,800,000 coins for the killing player regardless of charge.
