Specific skills MP Cost Rate

As you know, there is a parameter called 'MP Cost Rate' that let you alter how much MP skills will cost to use.

It's neat, but the problem is that it aplies "globally" to all the skills that use MP.

What I'm looking for, is a way to alter the MP cost rate, not globally, but instead only for some skills.

e.g, A certain character gain a "healing" affinity, and his healing spells now cost less MP compared to other characters. However, his damaging spells still cost as much for him as for other charaters.

Specifically, I would like to be able to alter the MP cost of certain skills if certain conditions are met (using notetags, maybe?)

Any help, suggestions, or scripts will be gratefully received.

Thanks beforehand, and sorry for bad english.

You can use Yanfly's Skill Cost Manager script. It's just a bit complex but what you are asking for can be achieved by setting your own custom costs with variables.

Pair this script with modern algebra's Global Text Codes script to allow variables to be shown in the skill menu when defining custom cost.

You can then use common events to reduce the specified variable by a certain amount whenever a condition is met.

Depending on how you set up the custom cost string, you can use the variable for single or multiple skills.

Well, that sounds quite complicated, but I will definitely look into it.

Thanks for the advice!
