Hello,
I read the FAQ on Sea of Blood and it states that monsters cannot actavite the revenge on Island levels. The FAQ also states you can not spawn on the Revenge during Island levels. For Encounters is this the same? Well, spawning you still can't as the monsters come on from the board edge. But I'm thinking that I can have the monsters board the heros ships and stier it of the game map.
In the FAQ FFG stated Island levels. I agree with this, having the Overlord being able to kick the heros out of the dungeon is a little to powerful.
I think FFG would have stated "Monsters cannot activate the Revenge" if they also ment the encounters.
