I know this subject has been discussed here before, probably a few times, but I don't think there has ever been an official answer.
It's to do with stacking movement affecting cards such as Torch, Magic Carpet, Riding Horse etc
I know generally cards of these types can't be combined. With Torch and Riding Horse that's very clear. As it is with Riding Horse and Clockwork Owl. But., and I think this caused a much discussion last time, can you use a Torch and Magic Carpet? Or a Torch and Amulet of Speed? Or even the Amulet of Speed, reroll and the use the Clockwork Owl? All very difficult questions to answer during a game.
I thought about it in this way:
If a card "Manipulates" your roll it can't be combined with another. So you can't use the Torch to roll two dice, choose one, and then use the Hunchback to move up to the die roll you choose. Similarly you can't use the Riding Horse to roll two dice and then use the Hunchback.
But if card "Activates" as the result of a die roll then you can use it. So if you use the Torch and roll a 6, you can then use the Leprechaun's ability or the Flying Carpet. Equally if you roll a 1 you can move the Reaper. It's in the FAQ that if the Amazon uses her ability and chooses a 1 she still moves the Reaper, so it makes sense to apply that ruling more broadly.
Obviously there may be combinations that sit outside of these two ideas, but generally I think they apply in most instances.
Thinking ahead, if you can only use one movement effect full stop, must you declare what that will be before you roll? So if I have the Amulet of Speed and the Magic Carpet, must I state that I'm rolling with the intent to reroll should I get a 1, thereby forgoing the Magic Carpet's ability should I roll a 6? (Ignore the teleport on the Amulet of Speed for this example). Would the opposite also be true? If I state I'm rolling with the intent to activate the Magic Carpet and I roll a 1, can I not then use the Amulet of Speed?
I'm sorry if I'm overcomplicating or overthinking things, but I think this needs clearing up, if only for my own sanity!
Cheers guys and gals.
