Nov 15, 2015 The double crossbow traces its invention to Absalom, though no single inventor is credited with its conception. It is a popular weapon among Absalom's public and private guards but is relatively rare outside the Isle of Kortos, except among followers of crossbow-favoring Abadar. (Pathfinder, 3.5, AD&D, etc.) Looking at some NPCs seems to be back this up. The Veteran (MM 350) deals a straight 1d10 with their Heavy Crossbow, despite having Dex+1, and the Scout (MM 349) deals 1d8+Dex with their Longbow. However, I cannot actually find where this is detailed in the PHB.

Pathfinder Crossbow Feats
As long as it holds bolts, you can reload it by pulling the reloading lever (a free action). Loading a new case of 5 bolts is a full-round action that provokes attacks of opportunity.
You can fire a repeating crossbow with one hand or fire a repeating crossbow in each hand in the same manner as you would a normal crossbow of the same size. However, you must fire the weapon with two hands in order to use the reloading lever, and you must use two hands to load a new case of bolts.
