Tetsu equipment

Tetsu equipment is a set of degradable melee armour and weapons unlocked via Player-owned ports. 85 Defence is required to wear the armour, and 85 Attack is required to wield the weapons. The armour can be made at 90 Smithing (and the weapons at 92 Smithing) in the port's workshop, which is not boostable. Plate is the trade good required for the armour's production, and the weapons also require pearls and a tengu tsuba.

Before the armour can be made, the ability to make the pieces must be unlocked. This is done by collecting 4 forgotten scrolls per armour piece. A total of 12 scroll pieces are required to be able to craft all 3 pieces of the armour.

The armour comes in two versions, tradeable and untradeable ('Superior'). The Superior version has higher stats than the tradeable one and lasts 12 hours of combat, compared to the regular version's 10 hours. The Superior version can be repaired, but the tradeable version cannot and will degrade to nothing. The lowest repair cost of the Superior armour set is at level 99 Smithing. This is not a level requirement however.

The weapons are exclusively non-tradeable.

Upon death from PvP, the Superior versions will be converted to the following regardless of charge:

Dying to an NPC simply drops it to the ground (or gravestone if outside the Wilderness) with 10% of its charge lost.

Trivia

 * The name Tetsu is based on the Japanese character "鉄" (pronounced Tetsu), meaning "Iron".
 * Tetsu, along with Sea Singer armour, received a graphical change on 14 January 2013. It has now a golden colour scheme, recoloured from the original teal.
 * Before the update on 7 January 2014, the Tetsu body and legs were known as the 'Tetsu Laminar' and 'Tetsu Legplates' in the Ports Management scrolls interface.
