legendary mod..again..lol

um..so there are extra quests apparently. One of which is called "rock the night away" for legends of aranna. There is no quest marker. It just says to collect your reward from the guy who owns "the establishment." that's all it says. Does not tell me who or where they are and there's no guides online...
I'm also very curious as to why the answer to making bosses difficult is geared towards them just healing to full. Was it not possible to make the fights the same as the first game (other than for obvious mechanical reasons such as party control)? cuz, the gom fight is not remotely similar to the og version. just curious.
