QQ im so lost lol

Hey how do you know if you did all the dk quest b/c i dont think i did all of them and i can find any more of them. im so lost help me plz some body that knows where all the dk quest are QQ i suck as a dk QQ lol thanks guys and girls later

hmm i dunno (also weird avitar? Creepy eyes lol)

I do believe that all the DK quests are in Acherus, there are NONE outside of it, with the exception of the Mograine quest where you must fight to take back Acherus, but I highly doubt that this works as the scripting is amazing even in retail.
