I was fighting a boss with a Storm dome up and it hit Storm Spectral a lot. I actually thought it was the dome making it Storm....... but no
Why not make Spectral Blast/Minion influenced by the type of dome up. It's so simple.
My original thought was to make Spectral Blast completely universal, but then again, we have Spirit Blast via a pet card. Why not make that a TC at least, if not an official spell?
Anyways, it's kind of unreliable to use it on an Elemental Boss, especially in Azteca (since they use Double shields), since Spectral Blast has the annoying habit of either hitting for their school, which they resist, or into a shield. It's especially annoying if it hits a single shield. With a certain dome up, you don't have to cross your fingers and hope it doesn't hit into literally the only shield there
Could you at least increase the odds of it hitting for that school (whose dome is up).
