Okay, so, a bit late with the video, since it's been like a week since I did this quest, but ehh, couldn't be bothered with video compressing and all that. Anyway, it's here now, and though I hate how fuzzy youtube made them, it'll have to do. :P
Part I - not much to say about it, you go to Roumen, talk to Roumenus, a bunch of zomboids spawn, you kill em! Worth noting is that you'll be poisoned nonstop.
Part II - ahh the gambling part. I hated it. It's one of those "guess a random number" things. I guess it's kind of like enhancing, except if you choose wrong you get mobs on you. Well, at least you don't break anything... except maybe your keyboard. The Gambler King Joker in the end is disappointing to say the least. Also note how I'm completely stumped in the beginning as to how the whole deal works, especially how to spin the roulette... go me.
Part III - the third part is actually about 20 minutes long... so I had to cut it by more than half. Anything you don't see in this video is just more of the same; the quest is nothing more than repeated spawns of those elf knights and lizardman knights. Not much to say here either, the third part was easy, but tedious and long.
