I would probably start here first:
https://github.com/EQEmu/Server/blob...ttack.cpp#L188
Which defaults to this - if no database rules are found:
https://github.com/EQEmu/Server/blob...letypes.h#L392
(My database rule value is set to '69.0' as well...)
How did you get 95.0?
EDIT: Duh!
https://github.com/EQEmu/Server/blob...letypes.h#L393
Try lowering the NPCBonusHitChance to see if that helps.
