DESCRIPTION

Calculates the probability distribution of a dice roll, anydice-style. For plain XdY+mod returns the EXACT distribution (mean, stdev, min, max, and P(>= target)); for keep-highest/lowest (4d6kh3, 2d20kl1) estimates via seeded Monte Carlo. For sizing DCs, damage, and stat rolls. Use it as a dice probability calculator API, dice statistics tool, or odds-of-a-dice-roll checker.
