Formula Reference

DPR = P_hit × avg_damage + P_crit × (extra_die + bonus)

P_hit = 1 - (AC - attack_bonus - 1) / 20 (clamped 5%-95%)

P_crit = crit_range / 20  |  Critical hits add an extra damage die + keep all bonuses

Advantage: P_hit = 1 - ((AC - bonus) / 20)^2  |  Disadvantage: P_hit = ((21 - AC + bonus) / 20)^2
