How to modify in game stats?

[sTNL]

Hi, just wanted to ask, how i can modify stats only in game, for example when you click on the arcana mace, to see some things that you want, not just 15%cast speed, etc, also the grade, to make it A grade for example, to see it A when you click on it, Thanks alot!
