                if (mylevel >= 28 && mylevel <= 39) {
                    if (min_dmg==0)
                        min_dmg = mylevel / 2; // 14-17
                    if (max_dmg==0)
                        max_dmg = (mylevel*2)+2;
                    // 28 = 58, 39 = 80
                }

If you do not set mindmg and maxdmg in the database this is the formula used. So level a level 37 npc hits for a minimum of 18 (note should be 19 we don't round everything up like live) and a maximum of 76

Now you may be thinking this is abit low but keep in mind that attack and str aren't factored.

So..

max_dmg = max_dmg + ( (str/10) * 2)
min_dmg = min_dmg + ( (str/10) * 2)

which gives your HG
str 105
min 40
max 97

Buffed with: Strength of the Diaku (lvl 63 shm) str buff 75
str 180
min 55
max 112

Buffed with: Yaulp II (clr 19/pal 39) close enough str buff 20
str 125
min 44
max 101

The default is 75 for stats so after the code addition
str 75
min 34
max 91
