When a bayonet is fixed to the end of a longarm, it turns it into a double weapon, with the bayoneted end dealing 1d10 piercing damage and the other end dealing 1d6 bludgeoning damage. You can fight with it as if fighting with two weapons, but if you do, you incur all the normal attack penalties associated with fighting with two weapons, just as if you were using a one-handed weapon and a light weapon. You can use either head as the primary weapon. The other is the off-hand weapon. A creature wielding a bayoneted longarm in one hand can’t use it as a double weapon—only one end of the weapon can be used in any given round.
