I've been playing RO2 on and off for sometime now. I've made ML chars of various classes, but I just recently returned (again) and chose to go with a SM for now. I found a guild, and was told that Wonderland dungeon can be solo'd by low level MLs. It got me interested, naturally, but I am absolutely clueless regarding how to get there in the first place. Despite my frantic googling, I'm not really much wiser (I wasn't really able to find any guide).
So, how does one get to Wonderland? (I know it's open only after enough donations have been made.)
