QTE-Based Percentage [In battle]

So what I've been wanting to implement into my game is a series of QTEs that will increase the chance of an attack happening (otherwise it fails). It seems simple enough although I haven't really found anything that could facilitate something like that just yet. Would anybody know of any plugins/alterations to plugins which could allow that to happen?

Not sure if this helps but it is a step in the right direction.
@Astfgl66 has a QTE script here: https://forums.rpgmakerweb.com/index.php?threads/quick-time-events-r2-26-11.71268/

You could use my plugin with yanfly's action sequence to alter hit chance upon QTE success, yes.

Thank you very much! Would you mind it being used in a commercial product? Also, I imagine I might have to do some coding to make it work. It's fine if not but any advice for how to start?

The terms of use are in the thread, but yes they allow commercial use as long as I'm credited and get a copy of the game.
It's not really difficult to use though I guess I shouldn't judge since I wrote it.
Start with simple QTEs using the examples and grow from there, and feel free to ask more specific questions when the need arises.
The script calls needed are in the plugin help section.

There could be several ways to do what you want, my first guess would be to use an action sequence to create the QTE, check for success and if successful add a state to the actor that increases its accuracy.
