This is a crossbow made out of a combination of Mithral and Adamantine parts. Due to the excellent tensile nature of Adamantine, the crossbow can store far more kinetic energy than a normal crossbow. Unfortunately, this means that it takes much longer to reload than an ordinary crossbow. It takes 10 - your Strength modifier Move Actions to reload an Ultimate Crossbow (to a minimum of 1 Move Action). Due to the excellent ratcheting system on this device, the Move Actions do not need to be consecutive. The Ultimate Crossbow is always masterwork, getting a +1 enhancement bonus to attack rolls.
