Hardened Steel Bolts

Description
"Arus the watchman grasped his crossbow with shaky hands, and he felt beads of clammy perspiration on his skin as he stared at the unlovely corpse sprawling on the polished floor before him. It is not pleasant to come upon Death in a lonely place at midnight."

- The God in the Bowl

Without bolts, a crossbow is just a really poorly shaped club.

Cimmerian bolts are made from hardened steel and penetrate deeply into armor, though one needs a supply of such finely made metal.

Cimmerians may be called savages and barbarians, but their understanding of metal smithing is relatively advanced. They know the riddle of steel, how to harden it for greater durability and vicious wounds.
