From Reddit: NO level sync when entering a dungeon with less that required players!

[Noxifer]

Is it actually confirmed you can go solo dungeon with this?
I seem to remember something about needing at least two... but I can't recall where I read that.

Well, even if you need one more person to enter, nothing says that person can't leave the dungeon once you're in, right? That's how we have the Solo Scholar Dungeon youtube videos =D
