I've had this game for two weeks now and am enjoying it very much. I've got some questions regarding gameplay however:
1.) If "Driven by Shadow" comes up as a shadow card, can I use its shadow effect to discard the "Caught in a Web" Treachery card attached to one of my heroes? I have so far assumed this is a legal move but am not 100% sure.
2.) If a Location leaves the staging area by having a number of progress tokens placed on it (i.e., using Northern Tracker or Snowbourn Scout) equal to the amount of quest points on the Location, is it considered explored? If I discard "Mountains of Mirkwood" in this way, does its response trigger? Again, I have so far assumed this is a yes.
3.) In the "Hunt for Gollum" scenario, can I claim an Objective the same turn/phase that I advance from Stage 2B to the next card without the reset occuring? I.e., can I just leave the Objective(s) in the staging area until the very moment I finish 2B, or do I need to claim it the turn before? Further, what if the Objective is guarded by the current Active Location, and this Location is explored and Stage 2B finished in the same quest -- can I still claim it and proceed?
1. Yes, but only if you are defending with the hero to whom Caught in a Web is attached (since Driven by Shadow says, "Choose and discard 1 attachment from the defending character."). Note, though, that if the attack is undefended, you CANNOT discard Caught in a Web, since that part of Driven by Shadow's shadow effect only discards attachments you control.
2. Yes. A location is "explored" whenever is has progress tokens on it equal to its quest point value. All relevant responses/effects trigger at that time.
3. Basically, yes. Signs of Gollum can only be claimed at a very specific time. Per p. 5 of the FAQ, players have "quested successfully" after staging, as soon as you determine that the total willpower exceeds the threat in the staging area (i.e. before placing progress tokens). At this point--and ONLY this point--you can claim Signs of Gollum if it is unguarded. THEN you place progress tokens. So, in the scenario you presented, you cannot technically "wait" to claim the objective until the very moment you finish Stage 2B; however, in the instant that you tally your willpower and recognize you will be placing enough progress to finish the stage, you CAN claim the objective BEFORE placing progress.
This timing answers the second part of your question. Basically, if the objective becomes unguarded after progress tokens have been placed, you won't be able to claim it until the next turn (since it was guarded at the moment when you "quested successfully"). If that were the only Signs of Gollum in play, you would immediately reset the quest deck.
Hope that helps
