When a Stuffy draws dice and they draw a black threat dice that would bring the number equal to or over the amount of enemies on the board the enemies activate.
What happens if during the Stuffy's turn they defeat an enemy dropping the enemy count below the number of threat dice? Do the enemies still activate since at the beginning of the Stuffy's turn the dice equaled or exceeded the amount of enemies on the board at that time?
If you drop the enemy count below the threat dice count, then yes they still activate. As you still have more threat dice than enemies...
