We were playing this saga quest this past weekend in a 4 player group and came up against an impossible result. We are on the last stage which has the text "Treachery cards gain surge." While we were doing pretty well we had enemies everywhere and a lot of locations in the staging area. But we weren't concerned since we had strong questing power and planned to just blitz through and win before getting to the next combat round. We'd ran out of cards from the encounter deck the turn before so I started to shuffle the deck while others finished their planning phase. - yes, we skip ahead a bit sometimes. When I picked up the discard pile I noticed that the entire thing - save 1 card - was all treacheries, one of which being to give all characters -1 will power and prevents us from attacking that round. It dawns on me that if we don't do something to add cards to the encounter deck, every card (except the 1 location) will get surge and we'll just repeat every card infinitely! Which begs the question -
What do you do when presented with an infinite loop of the encounter deck?
Luckily - our tactics player had a Rain of Arrows event and killed off several enemies, giving us just enough cards to NOT be stuck in the loop.
