SMT IV Skills (Skills level up when learned again)

Hello everyone. I'm making a game in which the player goes to a special college and chooses classes in order to learn new skills. However, like real-life college, some classes overlap in their subject matter, and you might take some of the same classes again. In a normal situation this might cause players to go out of their way to take classes that only give new skills, to maximize what they get out of it. There definitely needs to be some incentive for them to go for the same skills again.

In Shin Megami Tensei IV, the player had the option of reobtaining skills they already had, increasing the levels of those skills. Higher-level skills might have cost less MP, done more damage, had a higher status effect chance or the like. I'm looking for a script that will allow skills to level up when the same skill is learned more than once, adding the specific benefits and level limits by notetags in the skills. Maybe this already exists, but a look through many, many of the major scripts available hasn't turned up anything for me.

Thanks!

Most skill leveling scripts I think has a script call for increasing levels (my skill level script has that) so you could possibly use those calls after going to class. As for effects, you can use the damage formula to take the level into account. For MP cost reduction you can use scripts like Yanfly's custom cost script. Assuming the script ur gonna use has a call for obtaining the skill level (mine has those)


Looking for all of that in a single script can really make your life harder, as it's actually better to make them separate (modular as we like to say) so that you can easily replace/remove parts when needed.
