The Mortis Bat wouldn't happen to be a reference to OFF, would it? Considering it's the "Bat of Purification" and the developer is Mortis Ghost. As a fan of it as well as W&U, I have to respectfully nod to your good taste in RPGMaker games. It'd be funny if the battle music changed to "Pepper Steak" if Alicia equips it, though I'm sure it sadly wouldn't be possible.
