Try out a barkeeper contract in your house Senticore.
These NPC's can be programed with specific code words; and should the code word be spoken by a player character, such as 'Special1', then the NPC will say a phrase that has been predetermined by the house owner.
I believe Osi rules only allow us 2 bartenders, per say, but since we have upwards of four houses that's 8 total.
This give me an idea to share with Kane. I wonder if he can combine the two, so a players vendor can have code words that trigger special phrases. Then we could all set them up with specials.
Anyways I hope that helps a little.
