Ice Shard 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.
