Why not have it like Xrd where you can use a powered up version at the cost of the meter + Burst.
Not a bad idea of its own but giving more options to Burst is something I have been pretty skeptical about as it can possibly break the balance of my roster atm. I will think more about this.
Also, some update on Weiss: she is basically done (Glyph mechanics and Glyph moves basically work just like how they are in BBTag, 95%-source-accurate framedatas, Astral Finish,...). Some of these Astral FXs are just placeholders until I finish indexing the high-res Glyph FXs (big thanks to Ex★Cham for making those sweet, sweet Glyph FXs).

I will probably release the first RWBY team member in the next 2 weeks so stay tune.
