Can anyone help me fix my combat system? Or just explain what I need to do.

So i'm trying to make my items more accurate and more damnage. But when I give it more attack bonuses it doesnt make it more accurate.

For E.X.



I've heard lot's of things about my source being bad but idk what other source to use. Can i just rip a combat system off another source? and if so please explain how!


Thanks, Keith
