I was studying around your plugin. I must say, I need more time to fully understand but I can sense that it is a powerful free plugin.
That said, I tried to make a custom attack animation for the ARPG plugin set

Somebody has found a way to add custom attack animations sprite through an attack event in the set, albeit it is really simple.

Any suggestions to use your plugin in this manner?
