Drunken master/doc

Drunken master will increase character's melee to hit ratio and damage. Bonuses are random and floating for to hit:

    unarmed - Level of drunkenness / 300
    armed   - Level of drunkenness / 400

for damage:

    unarmed:
      min - Level of drunkenness  / 600
      max - Level of drunkenness  / 250
    armed:
      min - Level of drunkenness  / 900
      max - Level of drunkenness  / 400

Generally though, the more you drink, the better the bonuses are. For example, a single drink (drunkenness level +600) will increase your unarmed damage by 1-2.4 points and to hit ratio by 2 points, or armed melee damage by 0.6-1.5 points and to hit ratio by 1.5 points.
