1: ColorsBasically yes but colors are very important into the deduction process as they will help you to know that when a ghost of one color is found, no other ghost would hide under another tile from this color.
What's their meaning?
If I'm right, colors are needed only to create 4 decks at the start of the game and to hide ghosts in the rooms which match their colors. Is that all?
2: DevastationThe correct answer is a). You shall play only ONE of your ghost to destroy only ONE room at a time, then a ghost hunter will play, then a ghost, etc. Otherwise the game would be a nonsense and ghosts would win every time.
How does it work?
Ie: I'm a Ghost controller of 2 ghosts, and it's my turn: shall I destroy...
a) one room with one of my ghosts?
b) one room with each one of my ghosts?
c) more rooms with one of my ghosts?
d) more rooms with each one of my ghosts?
More, if I'm right, there are just few limits with this action, because it's (rulebook, page 5) "adjacent (horizontally, vertically, or diagonally) regardless of the color".Indeed, plus you can pass through the already destroyed room. But this is logical as long as you only destroy one room at a time. :)
Merci,De rien. ;)
