Both the Durge endings after you initially accept Bhaal are bland. Either you just get a boring ending where you take over the netherbrain, or you get an ending where you completely lose yourself and no one seems to miss you. In the end I felt like I was pushed to go back and do the resist route to get a satisfactory ending, which is kind of a bummer. I had planned on it anyway, but I was going to do a new run to get the resist endings. But after those endings, it didn't seem worth it so I just went back in my save files instead of doing another run.
