The Hunters’ crossbow:

Present in the Yanille Hunter store is Leon. Leon is an innovator, and famed (or so he thinks) inventor of the wind-powered mousetrap. This gentleman will, for the princely sum of 1,300 gp, sell you his Hunters’ crossbow - made from the bones of several small animals. The crossbow fires faster than other crossbows, and can be loaded with bolts made with kebbit spikes, gleaned from the razorback and prickly kebbits.

The kebbit bolts cannot be enchanted or poisoned.
