Sure.
Answered in my first post on this thread. Note that you cannot lose Wounds by any means while you are in the middle of missing that turn.
No, he's still worth two X's. They should be listed on his large Character Card.
Yes; an early version of the rules included a new version of Xykon's Throne Room specifically for Wandering Xykon instead of just using Safe Haven, and I guess we never caught the change on those cards.
His first turn occurs immediately after the turn in which his attention is caught.
As above, Xykon is a Monster that moves, not a player. He is unaffected by Room text that specifies players.
No, in that event, Xykon would stand still until someone re-entered the dungeon.
You can certainly institute that as a houserule if you wish, but by the rules, it should be distance, deeper floor, then random die roll. Xykon doesn't know who's the strongest unless he's looking right at them.
Yes, obviously the presence of Monsters in this case is an exception to the rule that you can't initiate PVP when there are Monsters present, because Xykonn is himself a Monster and it would be impossible to attack him at all otherwise.
However, to clarify: When Xykon and his Minion Stack are in a room with existing face-up Monsters, there is no difference between his stack and the stack in the room. Xykon is treated as being part of the room's stack, as are all the Monsters that are following him. Think of it as one large stack with Xykon at the top, all of his Minion Stack in order beneath him, and the entire face-up Monster stack in the room beneath them.
A room containing Xykon does contain Monsters, because Xykon is a Monster. Therefore, no, you may not pick up Loot.
Yes. Your chance of victory (in this case, nil) is not a determining factor in whether or not you must turn in the "I Got My Ass Kicked By Xykon" card. If you initiate an Attack that targets Xykon, you must turn in the card. (The card represents whether or not Xykon considers you a threat, and if you try to turn him, he'll consider you a threat even if you don't have a chance of succeeding.)
Note, however, that if you initiate an Attack that targets cards from his Minion Stack but does not include Xykon, you do not need to turn in the card.
He can take a second Wound that way, because that is a separate Wound source.
Yes, they can be moved from the Minion Stack. They must be moved to neighboring rooms because they are all considered the same stack while Xykon is present in the room.[/LIST]
No. No one can ever have more than 4 Wounds.
No, it may be used at any time, even during another player's turn.
Answered in my first post on this thread. SHort answer: "Sort of."
Yes, because the flipping of Battle Shticks does not occur until after the battle is concluded (Step 7, "Aftermath" in the core rules.
Yes, because they are affected by any card that affects all players in the same room.
It should only allow one Screw This! card at a time.
Yes, it happens immediately, before any other effect and before the trap/battle resolution. Strictly speaking, it happens as part of Step 5, "Make an Attack/Defense Roll," while losing a Wound doesn't happen until Step 6, "Apply Results."
No, it cannot be unflipped while it remains in a room, and she does not get it back until the Monster is defeated or would otherwise drop Loot. Note that because all Monsters disappear and drop their Loot when Xykon is beaten, she automatically will get her shtick back at that time if she hasn't already.
