The card reads the following:
Alric Farrow's card reads:
I've read two interpretations of this rule:
1. Unmovable allows Farrow to ignore the damage, as the damage is a part of the game effect that caused by the movement.
2. Unmovable prevents the movement, but does not prevent the damage, since the damage and movement are two different game effects for the same card.
Personally, I lean more towards the second, since a single card can technically have more than one game effect. Unmovable prevents movement, but the card does not say that damage is dependent on movement... a player can optionally choose to ignore the movement effect, and still have the monster suffer the damage, regardless of Unmovable (an example of them being two different effects).
Does anyone want to weigh in on this, or suggest a means of resolving the issue?
