I've just updated my editor to handle skill mods and bane/resist damage. It's still as flakey as it ever was, but it's probably easier than editing blobs

Some of the offsets don't work properly, diety doesn't appear to be anything but 0 for pretty much all items. Not sure what the correct number is for the bane race either, there are two, but they're also set for non-bane weapons.
These are the offsets I've used anyway:
UINT8 0xfc = Skill mod
UINT16 0xfe = Skill percent
UINT8 0x8c = Bane dmg race 2
UINT8 0x100 = Bane dmg race
UINT8 0x102 = Bane dmg race mod
UINT8 0x104 = Bane Dmg
UINT8 0x108 = Min. Equip
UINT8 0x109 = Min. Skill
UINT8 0x10b = Resist Dmg type
UINT8 0x10c = Resist Dmg
UINT8 0x122 = Diety
