* This feat can be added to iprp_feats.2da to make it available as item feat.
So as you can see its hardcoded into the game, only thing I can do at this point is to move the feat to a higher level of paladin and require a 2da download.

or
I think it was Xianio that said tag all people with the feat negative numbers depending on their paladin level.
Example:
A level 1 paladin and 19 rogue with 13 mod chr would get +13 to all saving throws. Xianio's idea would be to give the person -12 to all saving throws. Bascially cap the saving throw bonus to the paladin levels they have.
Problem we have with this is people are switching items all the time. So in effect I'd have to use pure charisma and not item/spell boosted charisma
Other than this, it blows that I can't modify it any other way.
