If it's not in Auto Passive States, you can definitely do it with Yanfly's "Weapon Unleash" plugin. You can just attach <Replace Attack: x> to a state, then apply the state. You would be replacing attack with either another proxy skill named attack or you could change it to something like "dual strike" or whatever.
Just finished and uploaded the delivery truck base/sprite sheet. I've been steadily replacing the default assets with early modern alternatives. The air-ship for a biplane, horse-drawn wagon for a delivery truck, and next a sailboat for a steam-powered passenger liner (think of the SS Olympic and RMS Titanic).
one of the coolest things I've learned from the forums is the ability to give yourself a hitbox. I have a move you can do on the fields. shoulder tackle. thanks to the forums, that tackle triggers self A switches on some events. NPC's and the environment now react to the tackle. awesome.
