Quick warning regarding the bandit sashes turn in - it will trash your faction with the necro's and SK's in Qeynos Catacombs. Since you are in the area, its a hard decision.
Pros -
- Extra exp for each sash (moderate amount - not like gnoll fangs which are pretty good for their level)
- Some more positive faction with guards, paladins and clerics
- Cash from the sales of bronze weapons
Cons -
- Quickly (yes, they are relatively large hits) damages your faction with your class trainers and spell vendors
