Off-hand demon slayer crossbow

The off-hand demon slayer crossbow was released on 28 January 2013. It is dropped by a demon boss, which will show up as part of a Demon Flash Mob at a number of places every full hour.

Although the crossbow is supposedly level 60 equipment, when used against non-demons it has the accuracy of a level 57 weapon.

Jagex has indicated that you will "get a boost to damage dealt and experience gained while fighting demons for each piece of the gear you equip. A full set of the gear makes the crossbows better than their dragon equivalents when fighting demons". This has been confirmed.
