I know that, but what about when I'm already in a fight? Example: I'm on the second floor, fighting a Black Dragon and a Goblin. The Dragon kicks my butt, thanks to his attack I can't even approach, and my turn ends. On the next turn, do I have to fight the Dragon again (only to get my butt kicked again, and so on until I get killed and have to run back to the entrance), or can I move away and leave the two in the room?
I misspoke in that sentence. Actually, the "employee exit" turned up on the 3rd floor, and the description says it has a ladder going down (which would mean to Xykon's floor). So how does that work?About "emergency exit" - you can use it to escape while the dungeon is collapsing, check the FAQ here.
But this room could never be in Xykon's lair: even on the shortest game the lair is on level 4, and the lair is made up from those special nifty black "Xykon's Lair" cards. (Check the "game setup" and "endgame" sections on how to prepare the lair).
Hope that helped.
And while we're at it: there can be only one found staircase, and there's the "employee exit", and I read in this thread there's another card giving a staircase. So there can be 3 staircases on the same floor? What happens if it's the last floor before Xykon?
