Pictures:

It is based on a Weapon of FF Tactics:
Parameters:* Same of the Rune Blade but with these changes:Str+5
Vit+5
Growth: TripleI made a swap between models, now the Enhanced Sword looks like the Rune Blade and the Materia Sword looks like the Enhanced Sword.
In my opinion looks very similar to the Materia Blade of the FF Tactics:

I hope you like this early Triple Growth weapon.
