Random Magic Weapons (any level)
(Self-revealing) valued at 2,600 gp.
Any bludgeoning weapon enhanced by this ability has its threat range doubled. For example, a quarterstaff thus enhanced scores a threat on a 19-20, and a heavy flail scores a threat on a 17-20. This enhancement does not affect piercing or slashing weapons. (If you roll this property for an inappropriate weapon, reroll.)
