Hi,
We have just finished Return to Black Star Rise (victory C2) but encountered this situation
Two players, Tony and Mandy, but Tony was defeated by horror, so mandy was on her own.
Agenda 2a / Act 3c (open the path above)
While on Abbey Tower (the path is open), i did draw "Hastur's gaze".
Fortunately, i did have a "ward of protection" and cancel the revelation.
Else i would have to add it to my hand... and Abbey's tower strictly forbid any clue discovering while having cards in your hand.
Hastur's Gaze is hidden, and "cannot be discarded from your hand by any means except those described on the card" (campaign guide)
Therefore i should not be able to discard it using location's ability ( Discard up to 3 cards from your hand ).
Sadly the forced effect need 1 doom placed on agenda c ... which did not exist anymore...
As i said, i did play ward of protection and escape this nasty trap, but is there a special rule to overcome this ?
Furthermore, it was not the end, as my next upkeep phase bring this
🙃
