This is a collaborative effort between me and Scinaya. The battler we based it on is from Thalzon's ReStaff release for RPG Maker Web. You can download the entire thing in batch either in RMW, Steam RMVXA Workshop or this album over here.
I downloaded and imported the little sprite sheet, but when I try to use it for an event, RMVXA only lets me use a small portion of a sprite. This and another sprite sheet of yours are the only ones this happens with. Any ideas?
