Displaying MP/TP Gain From Skills Like a Skill Cost?

[Soryuju]

I want to experiment with a system where using skills in battle generates MP or TP (one or the other, doesn’t matter) instead of consuming it. Each character’s target rate will be determined by their current MP/TP value. The end result will be that the more powerful skills a character uses, the more likely enemies are to target them.

My problem is that I don’t know how to display this resource gain from skills like a regular skill cost in the skill menu. I know I can make the values appear as popups in battle, but I want players to be able to see ahead of time how much each skill will increase the character’s target rate.

It doesn’t really matter to me whether I go with MP or TP for the resource - whichever is easiest to display in the skill menu is fine with me, unless anyone can think of other factors I should consider.

Let me know if I can provide any more information to clarify what I mean. Thanks!
