Did you ever wonder why equipping either the Bow or Arrow in either hand gives you 1 attack power?
The attack power listing of the "fists" is 1. This is never used in any another physical damage algo in the game.
When you equip either the Bow or Arrow, your attack power is increased by 1, which has been documented.
However, it is the empty hand that uses "these fists". It is changable within the game's data...
There is a similar behavior that goes with armor, where "empty armor" sections imply 0 defense, 0 magic defense, and 0 magic evade.
However, evade is 10%. These values can be changed internally...
Ok, back to your regular programming.
