How this is worked out

5 steps
  1. Effective attack = 110; attack roll = 110 x (0 + 64) = 7040
  2. Defence roll = (1 + 9) x (0 + 64) = 640
  3. Chance to hit = 95.441%
  4. Average damage per attack = 95.441% x 11/2 = 5.249254
  5. DPS = 5.249254 / 2.4 s = 2.187189

Effective levels add the style bonus and +8; max hit = floor((effStr x (strBonus + 64) + 320)/640); defence roll = (level + 9)(bonus + 64).
