Hi. I'm a bit undecided on this. I'm playing "The Drowned Ruins" (Dreamchaser Quest 4), which included the treachery "Powerful Undertow":

When Revealed: You cannot flip the active location this round. If the active location is Underwater , resolve its Forced effect as if it is the end of the quest phase. If there is no Underwater active location, Powerful Undertow gains doomed 3, instead.

Do you take the first sentence to mean the current active location, or does it also include a new active location, if you travelled to one in the Travel phase, for example? I actually played the latter in the end (a bit more restrictive, but often I wasn't flipping the new Grotto locations anyway, to allow me time to play allies and attachements).

Curious as to what people think.

All encounter card effects recalculate whenever a new card enters play. For instance, a location revealed after Treacherous Fog will still get the threat boost. I'm assuming this applies to the active location spot as well. However, this does not apply to player cards.

I can see that it seems a bit ambiguous, but I'd be confident in playing it the way you did.

I agree with Wandalf. It create an effect that say "If a location is the active location it can't be flipped" until the end of turn.

About his last sentence it can be ambiguous so I prefer to explain it: a player card with the same text would only affect the current active location.

Thanks all, for the replies.

I was unsure because the normal language ("Until the end of the round / phase") wasn't used here, and obviously the effect had to last beyond the end of the phase in order to keep you under water, which I suspect is the main intent of the card (otherwise you get into the "Until the end of the phase / At the end of the phase" debate).

Fortunately, the impact on a new active location is minor - keeping you on the safe side of the grotto, albeit potentially slowing you down 1 round.

It has the normal language you speak about. This round mean it last until the end of the round. It is a pretty common way to write this kind of effect.
