Say I'm playing Merisel. One of her powers is that she can evade encounters. She runs into a Skeleton Horde, which summons an Ancient Skeleton. Can she evade the Ancient Skeleton? If so, what happens to it? Does the Skeleton get shuffled into the location or does it get banished back to the box? If it gets shuffled into the location and someone later defeats it, does that trigger a closing opportunity? If not how does one distinguish the summoned Skeleton from a Skeleton already in the location?
I read on BGG site that summoned monsters like this can be evaded, and that they are sent back to the box rather than the location deck.
