Hello,
Don't you think that when a hero with Asfaloth attached to it is sacked Asfaloth should be discarded?
Because in the opposite case why cannot Asfaloth do its job? It really looks to work by itself really.
The obvious answer is no it cannot do its part untill attached hero is freed,
It is the logical but do the sack cards really forbid it?
I speak about "We must away ere break of day" but I believe the question is about "Conflict at tha Carrock" also.
