As thief 90 I currently use sleep bolts to interupt the magic casting of Blackmage enemies I farm for money, however this can cost me alot of ammo, and when I miss costing me my life sometimes. It would be more effective if there were silence bolts to help out with saving me ammo and my life. Improving the soloability of jobs that can use the enfeebling bolts.

Adding silence bolts will also add a new recipe for wood working and alchemy crafters.
