Bat masks are obtained as rewards from level 2 clue scrolls in Treasure Trails.
Bat masks came as part of the 15 April 2008 treasure trail update, together with other animal masks, the top hat and canes.
This mask gives no bonuses, and so is purely cosmetic.
- The examine text of the bat mask is a line from and possible reference to the song "Bela Lugosi's Dead" by the gothic rock band Bauhaus.
- The examine text is also a possible reference to the saying "bats in the belfry", meaning that someone is insane or crazy. A belfry is the same as a belltower.
