Hey all, I'm currently at the point in the game where I need to choose between the 3 factions in Defiance Bay, and I've built my Rogue around crit, so I want to go with House Doemenel. The problem is my reputation with the Knights is significantly higher than Doemenel, so they won't accept me.I've tried killing the entire keep of Knights but even with my reputation being lowered to Dark Hero from that, the leader of Doemenel still won't let me join, any ideas on what I can do to join Doemenel?
