From what little testing and setup I've done so far, I have to say I'm impressed. So thanks for having a working VX version of this... it's made life quite a bit simpler.
But there is one aspect of this system that is completely missing, and I'm rather surprised that SephSpawn didn't include it in the original (or if he did have it, that it got cut out). Late in FFVII, you have the ability to combine all the Mastered Materia into a single Master Materia. IE, once you mastered one of each of the Magic-type Materia, they were combined to form a single Master Materia that gave access to ALL of the spells in the game. The same thing went for the Support, Summon, and Command Materias.
I figured that making such a materia shouldn't be hard, using the system that's already in place. Then I really looked at the notes, and I no longer think it's possible, as it would appear that you can only gain one spell/ability per level of Materia... so putting the IDs of ALL the spells in wouldn't work. Especially since the Materia would already be a Master on receipt.
When you DO get around to the next version (understanding that this may be some time, with the other scripts being worked on), could this glaring ommision be remedied?
