The ruined dragon armour slice is part of the dragon platebody, along with the ruined dragon armour lump and the ruined dragon armour shard. Any of the three pieces are possible rewards from the While Guthix Sleeps quest. When taken to the dragon forge, found in the Ancient Cavern, a player can unite the three ruined dragon armour pieces into a dragon platebody with the use of a blast fusion hammer. A player must have completed the While Guthix Sleeps quest and achieved 92 Smithing to create the Dragon platebody; simply use one of the three ruined dragon pieces with a heated anvil. The assist system may also be used to create it.
Tormented demons are also known to drop it and appear to have this particular broken dragon armour piece as their left hand and forearm.
- This armour slice closely resembles the Tormented demon's left claw.
