I'm just getting started with RPG Maker, and have immediately jumped into trying to completely overhaul the combat system. I've got Bobstah's Custom Stats, Yanfly's Battle Engine (& Action Sequences), & Victor Engine's Hit Formula plugins, which are a good start.
The really big question I have right now is: how do I set up a skill to have an effect on a miss? I'm loosely basing my combat on the 13th Age system, where an attack will (for example) do 3d6 damage on a hit, and a flat 3 damage on a miss. Other skills might always apply a status effect, and only do damage on a hit.
I'm absolutely not opposed to mucking with scripts or even writing my own plugins, but I'm still feeling my way around RPG Maker, so I'm not really sure where to start.
