Is the affect of the clock striking midnight completely random? Reading the actual dice game rules, it sounds like the affect is selected from a card deck. (I've only play the phone game version).
Sometimes it's a monster, some times it's doom token, every once in a while, there's no affect. But my last game, I was ahead 8-2, & I got a +3 doom token midnight affect. I'd never seen 3 tokens gained at once. So I guessed the big jump was due to my being so far ahead.
Also, when looking at Azathoth's card info, the doom token tracker has alternating doom token & monster symbols on it. So I kind of thought that kind of indicated when a monster would appear. But it this hasn't always seemed to be the case.
Finally, the clock advances once with every investigator's turn, right? So since the phone game is hardcoded to have 4 investigators & there's 4 clock positions, then midnight will always fall at the end of the 4th investigator's turn, right? Assuming none have died? Midnight's always seemed to be a bit variable to me, but maybe it's just my perception.
