You can get 100% vs prone or unsuspecting enemies.
How does it work though? Technically you could still roll 2 1s.
Anyway, here's 50 100% throws. As usual, advantage favors critical hits over critical misses. Even over these comparably small samples, you can always see where this is headed. I think I have recorded well over 5-600 rolls now in this thread. TyPinOwly contributed some atop of that.If there are bugs right with the RNG, they sure aren't obvious any.
