The obsidian platebody is part of the untradeable and degradable Obsidian armour set. It requires 60 Defence to wear, and can be made by smithing five obsidian bars, requiring 85 Smithing. Obsidian bars are made by smelting obsidian shards, which in turn are dropped by monsters in the Fight Cauldron.
In addition to its defensive bonuses, it provides a 14% reduction to damage from creatures and players in TzHaar City.
With an update on the 30th April 2013, the armour no longer triples damage taken by you when fighting in PvP or any other monster.
When used with the rest of the obsidian armour and either a melee, ranged or magic helmet, it will increase your accuracy by 10%, very similar to the Void Knight equipment.
The Obsidian platebody degrades after 4000 hits, similar to the Tokkul-zo. Once it fully degrades it cannot be reused, and a new platebody must be smithed.
