The off-hand exquisite crossbow is a multi-tier weapon obtained from the Squeal of Fortune. It is won together with receiving the Exquisite crossbow. It has the option to switch from level 10 to level 40 stats. It can be reclaimed from Diango for 1,000 coins at level 10 and for 10,000 coins at level 40.
For a time when the various exquisite weapons were released, the certain items with off-hand variants were wieldable by free-to-play players. It was then changed so that the off-hand variants were un-wieldable by free-to-play players on 6/4/13. However, this weapon can still be obtained by free-to-play players.
