The text on the card Mirror Image says:
"If you are dealt damage by a monster during your turn, you may discard this card to roll 1d4, and on a result other than 1, reduce the damage to 0. Roll again for each additional source of damage for the rest of the turn."
The revised wording in the FAQ says:
"If a monster deals damage to you, you may display this card, even if you have played another spell on this check. Roll 1d4; on a result other than 1, reduce the damage to 0. Do this each time a monster deals damage to you. Discard this card at the end of the turn."
A) The original wording suggests that you can only play Mirror Image on your own turn ("during your turn"), but the new wording doesn't have that. Does that mean that I can cast Mirror Image on someone else's turn? (Say, to avoid damage from a monster that damages "everyone at this location".) The new wording doesn't say "during your turn", so I'm presuming it's legitimate to cast this spell to avoid damage on someone else's turn.
B) Secondary question: the original wording suggests that you have to initially play the card when a *monster* does damage, but after that it's "for each additional source of damage" -- so for example if I encounter a monster and get hit, I cast Mirror Image; if I then explore again and a barrier hits me for additional damage, I could roll again to possibly avoid that damage as well. The new wording says "monster" in both places, so is it correct to assume that the card *only* mitigates damage that comes from monsters, not from other types of cards?
