No, these shticks flip the card with no effect, denying their owner the usage of the card until they rest.
One bonus overall per battle roll, not one per loot card given.
No. You may have won the battle, but the Monster is STILL the top Monster on the stack. The rules only allow you to battle the top Monster, requiring you to remove the previous Monster before you can battle the next one (which then becomes the new top Monster). Since Swipe doesn't move the top Monster, you can't get to the lower Monsters, and you can't battle the same Monster twice.
You can, however, defeat the top Monster with, say, Longbow, discard it, and then Swipe the second Monster.
No, that is incorrect. The rule stands no matter where the players are in relation to one another.
The purpose of the rule is not to get players to offer Loot to the PCs per se, but to prevent Player A from offering all of Player B's Loot to the NPCs, causing it to be put in the Loot discard pile and removed from play, possibly for the rest of the game if the Loot pile isn't reshuffled.
You wait until you are called on to play a Monster and can't. If you can play the Screw This! before then, you may.
Definitely.
With a Ranged Attack, you may never continue to battle Monsters. You may only make one Ranged Attack on your turn, and only against either a player or the top Monster in a room.
If you were in the same room, you would be required to fight the top Monster only. You can't battle a player on the same turn that you battle Monsters.
This is an error in the rules; you should be able to save them.
Yes, but multiple shticks DO provide the bonus listed on that shtick under "Boost".
Yup.
Monsters moved by Poorly-Planned Illusion do not attack any players in the room to which they move.
