Some problems with the combat code:

[jsr]

A good way to parse;

1.Copy a mob
2. Set min dmg to 1, max dmg to 20, str to the value you want to test
3. Set attack speed to -99 (fast)
3. Create an item with 999 regen and 9999hp . I use one of these for ac 10-1000 in increments of 10
4. Adjust regen cap in server rules to 999
5. /log on, equip item, spawn mob and attack.
6. #damage mob when you want to end fight.

I do this for mitigation testing, it is pretty fast. Gamparse will give you a breakdown of the # of huts at each dmg interval from 1-20. You can graph this to see where the bell curve is compared to live, and increase/decrease str until it is close to where you want it.
