Okay, Monte Carlo'd it because apparently I'm having a mental block today and can't math.
With Toryn on every shot, on an Adar + Yavaris triple-tap, you have:
- 92% chance to proc at least once
- 61% chance to proc at least twice
- 20% chance to proc all three times
and
- 31% chance to proc exactly once
- 42% chance to proc exactly twice
Never tell Gink the odds. He will still wipe all your squads with his lone Numb!
