Choose a specific organization, such as a town’s militia, a particular church, a guild, one of the illumian cabals (see Chapter 3), or other affiliation {PH2 163}. You have strong personal connections within that organization, as well as insight into its membership.
Benefit: You gain a +4 circumstance bonus on Bluff, Diplomacy, Gather Information, Knowledge (local), and Sense Motive checks made in conjunction with that organization.
Special: You can gain this feat multiple times. Its effects do not stack. Each time you take this feat, it applies to a new organization.
The DM should limit characters to selecting only those organizations with which they have a positive or neutral relationship. For instance, a character might not be allowed to select an enemy organization, or one whose existence and/or operations aren’t well known to him.
