The last one I did for him was to go to see Sister Sam. I had to fight her, then she gave me a sparring bot that I had to fight as well. I broke it and had to go to a gnomeland security to get it fixed. After i did that I went back to her and gave the bot back to her then meditated for a bit. I heard the little "ding" sound sound and saw the message that I had completed, then I saw the message that I was supposed to go back to merrick, so I did. I clicked on him and I can't remember what he said but it was something like "i taught her patience because i'm so noob". I clicked on him again and he says to come back when i've learned more....?
There's a journal online that tells what all the quests are in this quest line, and I know what i'm supposed to do next (go to lesser faydark if I remember correctly). The thing is Merrick isn't telling me to do it. As far as my Quest Journal is concerned, i'm all done with him and have no more quests in Butcherblock. I just don't know what it is i'm supposed to learn (or get or kill or do etc...), and my quest log doesn't say anything at all....?
