Roll count

How it is counted

s = base chance / 100, L = current Luck.

Luck roll values: d = |L - 5| / 10; n = 1 + floor(d); r = d - floor(d).
Favorable chance F(s, L): If L >= 5: F = 1 - (1 - s)^n * (1 - r * s)If L < 5: F = s^n * (1 - r * (1 - s))
Selected check: Good check: P = F(s, L)Bad check: P = 1 - F(1 - s, L)
Base critical chance: Crit base = min(max(L * 2%, 0%), 100%). Crit Chance Up bonuses are separate.
