D20:Crossbow, Light Weapon

You draw a light crossbow back by pulling a lever. Loading a light crossbow is a move action that provokes attacks of opportunity.
Normally, operating a light crossbow requires two hands. However, you can shoot, but not load, a light crossbow with one hand at a ?2 penalty on attack rolls. You can shoot a light crossbow with each hand, but you take a penalty on attack rolls as if attacking with two light weapons. This penalty is cumulative with the penalty for one-handed firing.

Increase total cost for magical enhancement by 2,000 gp for cold iron weapons. Unlike the additional cost, the increase the weapon's hardness and hit points are only gained from its enhancement bonus, not its special abilities. If the weapon has a magical bonus greater than +5 or a special ability worth more than +5, the weapon is epic. Multiply magic cost by 10.
