Notes

If Target or Attacker is Serpentarius Compat is Neutral
Compatibility is defined by Substracting Zodiac signs Nibble : 0x01 = Taurus to 0x0c = Serpentarius

Zodiac difference is used as an offset to load a byte at 0x8018f00 : 
Offset    Value    Compat
0x00      0x00     Neutral (same sign)
0x01      0x00     Neutral
0x02      0x00     Neutral
0x03      0x01     Bad
0x04      0x02     Good
0x05      0x00     Neutral
0x06      0x03     Best/Worst - drives to Gender Comparison 
0x07      0x00     Neutral
0x08      0x02     Good

0x0a      0x00     Neutral
0x0b      0x00     Neutral 

Gender Comparison :
 - Monster (Target or Attacker) : Compat Mod set to 0x01 : Bad 
 - Same Gender : Compat mod set to Worst : 0x04 
 - Different Gender : Compat mod set to Best : 0x05

secondadvent Compatibility patch

A rewrite thanks to SecondAdvent.

This rewrite saves a large amount of space (from 0x80184a2C to 0x80184b23) and gives freedom to change the compatibility damage changes as well as an accessory to neutralize compatibility damage.
