Suppose the Scholar places Don't Dismiss Anything (DDA), chooses to play the top card of his deck, and reveals Know When to Hold Fast. How immediately does his turn end? Do you finish resolving the effects of DDA, letting other players play the top card or get a card from the trash?
There was an old thread about DDA, but it didn't discuss this point (despite mentioning Know When to Hold Fast): https://greaterthangames.com/forum/topic/dont-dismiss-anything-interactions-4587
Turn would end right then, but before the next turn begins the rest of DDA's effects (and those of the cards it plays) would resolve.
It will work like PW Fanatic's Resolute playing Prayer of Desperation, your turn ends, then one player may use a power, but you don't get to re-use Resolute because it counts as still having been used that turn.
Correllary question: You play DDA, which plays Know When to Hold Fast, which moves you to the "end of turn" phase. Do End of Turn effects (such as Gloomy's voodoo pins) happen before or after DDA finishes resolving?
I would say they happen first, but I could easily see it going either way.
I believe that if you play Know When to Hold Fast, you skip the entire rest of your turn, including any End of Turn effects. The Scholar is too busy relaxing on the beach to be bothered by Gloomweaver's pesky pins.
No it only brings you to the end of turn triggering those effects and allowing you to prolong your turn when wager master puts the inverted phase order in play.
Oh, somehow I missed that Scholar was out in the video game.
From the above discussion, it sounds like phantaskippy's interpretation is right: you skip to the 'End of Turn' phase (immediately), but the processing of the card text continues.
That is correct and actually an item I brought up for discussion in the alpha testing. Scholar goes to the end of his turn but any remaining players still get their option for Don't Dimiss Anything.
