I have posed the following questions to Caleb and will report back once an answer is received (in the mean time, feel free to discuss):
1. What phase are the players in, if any, during the Escape test action window provided by Gollum's Forced effect in the Dead Marshes scenario?
2. Assuming a player has an effect that is limited to "once per phase" would the player be allowed to trigger this ability during the action window provided by Gollum's Escape Test and then also trigger it during the Travel phase, potentially stacking the effects that would both subsequently expire at the end of the Travel phase?
3. Also, does this ruling also apply to "Until the end of the round effects" and "At the end of the round effects"? In Battle of Carn Dum, for example, it is possible for Thaurdir to attack you as a result of flipping. This flip is triggered by the Forced effect on the quest card that triggers "At the end of the round". This attack provides the players with an opportunity to trigger actions during the attack steps. So, if a player triggered an action that "lasts until the end of the round" during an attack made "At the end of the round" would it persist through the entire next round? If so, my first question also applies here. Could you stack multiple limited "once per round" "until the end of the round" effects?
4. Would Beorn (ally) shuffle back into your deck if you used his action during such an action window, since Beorn specifically says "At the end of the phase in which you trigger this effect, shuffle Beorn back into your deck.", I assume he would stay in play and wouldn't even shuffle back in at the end of the Travel phase (in the example with Gollum).
5. When you are resolving "At the end of the round" effects, are you considered to be in any phase? If so, what phase?
6a. What happens if you trigger Beorn's ability during an action window provided by an attack "At the end of the round" or "At the beginning of a round" since neither is a "phase" and Beorn's ability specifically says "At the end of the phase in which you trigger this effect..."
6b. If Beorn stays in play, can you trigger his ability a second time in the Resource Phase of the round and have +16 attack from both triggers of his ability?
6c. What happens, for that matter, if you trigger any "until the end of the phase" or "At the end of the phase" effect during an action window provided by an "end of the round" or "beginning of the round" attack since you are not actually in a phase?
7. With respect to Full Sail Ahead and the Weather Turns Foul quest cards in Flight of the Stormcaller, what, if anything, prevents the players from being Forced to place progress on Full Sail Ahead at the end of the round, immediately advance, and then have to also place progress on the Weather Turns Foul?
8a. You said that Eowyn's ability would end right before Gollum's Forced effect started if you had chosen to trigger it during the quest phase. Is this still true?
8b. If this is still true is it fair to say that if any "at the end of phase" or "until the end of the phase" effects are activated within that "suspension timing" you mentioned, that once the players resume play, they will start resolving all remaining effects (those that still needed to be resolved before the suspension and those that were started within it) in Passive > Forced > Response order?
9. What happens if an action window is provided by an end of phase effect (like in the example with Gollum's Forced Escape test) and during that "suspension timing" a new encounter card is revealed that happens to have an "end of phase" effect? Will it also be immediately resolved once you continue play?
10. I asked Caleb about a potential inconsistency in rulings and asked him to explain why the two situations resolved differently. The following answer was received:
11. Would Beorn ally's effect be considered a lasting effect AND a passive effect or just a passive effect (assume you trigger his action during the Eowyn / Gollum Escape Test example). Specifically, the part that says "At the end of the phase in which you trigger this effect..."
11a. To my knowledge, "lasting effects" are a subset of passive effects and are typically structured with the following wording: "Until the end of the phase, X". Is this correct?
12. If you use Vilya to put Dwarven Sellsword into play during an attack made by Thaurdir flipping "at the end of the round" in the Battle of Carn Dum, I assume based on the Forced effect ruling you would not have to trigger the Forced effect on Dwarven Sellsword that round since it was not in play at the time its specified trigger was met. Is this correct?
