Badly need help with this one. I already went to the Misty Abyss and couldn't find the werewolves missing info.
The 1st pic is I'm already at the last floor of Misty Abyss. Can't unlock that door though. Please help. 
The answers to that quest should be on the second floor of the misty abyss. The two skull markers on the top right that usually have a swamp monster should have a werewolf that has been taken over by one of them. I can't remember if you actually need to check the question mark in that spot, but I think you do.
