Off-hand black longsword

The Off-hand black longsword is a black longsword equipped in the offhand slot. It requires an Attack level of at least 25 to wield. It can be found as a drop from the tormented wraith and several other monsters. It can also be obtained from chests that require steel keys in the Shade Catacombs, Level 1 Treasure Trails, or by trading with another player.

Trivia

 * Prior to 17 June 2013, the Off-hand black longsword was completely unobtainable, as it could not be smithed and was not dropped by any monsters, despite being listed on the Grand Exchange.
