Just a geek, nothing to see here, move along
The rulebook, in the setting up for the end game, says:
The Endgame uses the Endgame mini-board (south quadrant of the main game board). The entire mini-board is considered one Location.
Take the Antagonist from the Antagonist box in the top left corner on the board and place him in the Endgame Antagonist box. This indicates that
rules on the Antagonist card are now active.
So, the first time we played we assume that the rules of the antagonist applies for the final 3 challenges. However, we read in the story guide the following:
The Antagonist special rules are not active until the Final Showdown. That is, investigators will not benefit from the “Spellcraft is Wild” ability before the Final Showdown.
So, we are assuming that we should follow the rule in the story guide book.
If that is correct I think that rule should be phrased similarly in the rulebook.
We have been using the app so pretty much we ignored the guide book.
Maybe the rule in the rulebook makes more sense for the other stories.
