Titanium platebody

Titanium platebody is a members-only melee body armour that requires 55 Defence and the completion of the Iron Enigma quest. The titanium platebody is made by melting iron with the element titanium, thus creating titanium alloy which is lightweight and very strong. In the quest you will learn how titanium metal is made, although you can't create it yourself. After the quest you can pay Tybalt 50,000 coins to let him charge your titanium platebody. This will temporary raise your platebody's strength bonus to +8. After approximately 24 hours of combat the titanium platebody's strength bonus will decrease back to +2.

Because of the fact that titanium platebody is not tradeable and it needs the completion of the Iron Enigma quest it is not very popular even though, while charged, it provides the best strength bonus for a body armour in the game.
