My abandoned village is up to 11 now. I don't know if there's a max level, but I would wager there isn't. Each time a dungeon levels up is (usually) a chance for the player to spend gems. I doubt they would want to limit your chances of gem spending, hehe.
I've got a dungeon at lvl 41 and it seems there is no end in sight. It also appears that the scaling of dungeon progress needed to lvl up a dungeon stops after a certain point.
The Halloween update says there are new monsters and their dark master. Does anyone know anything about this dark master? Is this a titan that shows up in the grave area? That's my best guess, so far, since I don't see anything else. If that's the case, do we need to kill the other titans on the home island in order to get the halloween one to spawn? EDIT: Nevermind. Just saw that someone said the lich king unlocks once both halloween dungeons are level 5. Gloomy castle is a bit slow going, since that turtle is a 15 hour kill. Plus I had a 6 hour tame in there earlier (jack-o-spider).
The solo coffin on the southwest part of the island is kinda telling, though I haven't gotten both dungeons to level 5 yet. My fighting timers have been increasing rapidly.
That tombstone opens up into "The lich's lair" once you get both of the halloween dungeons to level 5, the only monster in there is the lich king (Guess the developers are big "Warcraft"-fans ), and every time you defeat him the fight time goes up, i defeated him in 12 hours today (which took the dungeon to level 2), the next round takes 24 hours... I'll keep fighting (and hopefully defeating) him, and will will let you know if anything awesome happens when the lair reaches level 5
Oh man, I need to hurry up and get in there! Lol. This stinking gloomy castle is taking forever, though. I got stuck taming both event pets in there, plus that turtle takes freakin' 15 hours to defeat, lol.
Did Wind not win the faction war? :/ They were at 54% 2 hours before it ended. But I don't have the buff.
Wind won. I got the notification in my castle. Can you check your heroes? They should have the +x% to dungeon progress in their stats.
