The updates have been on the server for a few hours now. There's now a dungeon on the central island of main which contains both hard and easier monsters. If you kill the monsters you'll be taken to an underground dungeon where you can progress deeper underground. As you go deeper, the monsters will get harder. You might eventually find some surprises as you go down, too
.
If you're planning on trying the hard dungeon, you'll want to take a few friends with you, as it's very difficult to survive.
It'll be to your benefit to collect as many Christmas Tokens as you can in the next few days.
We've fixed a couple kinks now, but if there are any other problems contact me here or in-game.
