okay, so if there was an empty board and you play grim patron and mad bomber, what's the expected value for the number of patrons? what's the probability of ending with 3 patrons?
or better, madder bomber.
For each bomb its:
33% chance before the first hit. (1 patron vs 2 faces)
50% chance after the first hit. (2 patron vs 2 faces)
60% chance if both hit earlier (3 patron vs 2 faces)
I think that makes it about a 10% chance to end up with 3 patrons. That is assuming each spawned patron is also a target for the bomber, other wise the math changes.
