You have guild connections which allow you to procure information and black market items with ease.
Prerequisite(s): 1st-level Assassin, membership in an assassins’ guild or criminal guild
Benefit: When you choose this feat, choose an appropriate guild in which you are a member. As long as you have reasonable access to that guild’s resources (such as by being in the appropriate city or able to find a contact), you are able to procure poisons and other alchemical items at nine-tenths of their market price without needing to haggle. In addition, you are able to make Appraise and Knowledge (local) checks with a bonus equal to your level in assassin by speaking with your guild contacts. Even when you do not have direct access to your guild’s resources, you make such checks with a bonus equal to one-third of your Assassin level (minimum +1).
