Speak with Dead on Lord Gortash - Patch 6 Update (Voice Over Added)
Still a bit glitchy with the subtitles, but finally fixed and with VO after months! Im very happy :)
Also my character is a barbarian--I wonder if he says all of the classes? I think I saw someone where he said 'druid' instead.
AFAIK these are all the options you get to ask, but maybe there is more if you chose not to side with him and do the iron throne and foundry quests.
