Some cards have things happen when you roll a certain result on the movement die. For instance, the Troll has the option of regenerating:
Whenever you roll a 6 for your move, you may regenerate instead of moving. If you choose to regenerate, heal one life and your turn immediately ends.
But how does this work if you roll two dice for movement? For instance, the Riding Horse:
You may roll 2 dice and add them together to determine how far you can move.
Or the Torch:
You may roll two dice for your movement in the Dungeon and choose one of the results to use for your move.
How do abilities that trigger based on the result of the movement die happen when either die has the value?
