A game is a series of decisions; a good game is a series of interesting decisions
playing this awesome game and trying to close a gate, not seal it, but just just close it. i decided to do a lore check of four, with the gate adding +1. so i roll 5 dice. how many successes do i need to close the gate?
Only one success unless Yog-Sothoth is the Ancient One:
"The Key and the Gate - While Yog-Sothoth stirs in his slumber, the difficulty to close or seal a gate increases by 1."
Also note that it doesn't matter whether you are trying to close or seal the gate - any time you successfully close a gate, you have the opportunity to immediately spend 5 clue tokens to seal it instead of just close it.
