How do i add.....

[kridak]

Hello folks

I am creating a pair of bracers that allow the wearer t release a tiny breath weapon from them. I need to have them show up in tracking with the users CHA bonus as numbers of uses per day.

I have been looking into the claws for sorcerers to try and figure out how to do this but i am clueless. this is what i tried so far.

~Uses is the CHA bonus per day
field[trkMax].value += hero.child[aCHA].field[aModBonus].value

I am likely way off, can anyone assist me or lead me to an item that has charges per day based off of a pc's stats?
