Combatant HUD shows everything at once.
Imagine you have 100 stats and you will need to scroll all of them just to know that current changes will be done.
I guess I could somehow cheat. Create string game variable and change it as I like upon inspecting (calculate currently equiped benefit and format them through code). And show that through custom text code (more/game variable).
I would still prefer some built in way to get information in text from custom code by calling formula or c# static method.
