Seems like the backstab skill is missing the magic number. Looking at the graph of Tigole's damage you have three main numbers - Minimum damage (120), Magic Number (194), and Max damage(449).

Not entirely sure if this is the calculation that is still used here for the backstab formula, it could be different.

Maximum Damage Calculation:

((Offense or Weap skill) + Str) / 100 * Weap Dmg * (2 + (Backstab skill * .02)

(252 + 209) / 100 * 15 * (2 + (225 * .02) = 449.475

From that graph you can gauge his strength to be 209 at the time if this is correct for Max damage.

Calculating for his Magic Number damage (194) the best I could come up with was this:

Weap Dmg * (2 + (Backstab skill * .02) * 2

15 * (2 + (225 * .02) * 2 = 195 (194 - something in the forumla isn't correct)


Another note here on hit distribution. Different classes have different percentages that all range between the three main numbers - Minimum damage, Magic Number, and Maximum damage. What was done back then was to use this for each one.

These are just made up percentages, they are not correct. For example, say you have a Monk that is level 60 and fighting a low dark blue (46). His hit distribution may look something like this:

30% Min, 60% Magic Number, 10% Max

Replace that dark blue mob with Trakanon and you would have an entirely different distribution:

75% Min, 20% Magic Number, 5% Max

Different classes have different spreads representing the damage tables also.

Monk vs Dark Blue mob (46)

30% Min, 60% Magic, 10% Max

Ranger vs Dark Blue mob (46)

45% Min, 55% Magic, 5% Max

Several factors affect these calculations - Player level, Player class, Attack, Mob Level, Mob AC etc.
