Materia System

[Amineri]

I guess armor/weapon can be destroed while atempt to attach second materia.

Fair enough, but I was referring more to the situation where you have a really nice rare materia that you'd like to keep, but you want to upgrade your armor or weapon or tool, and you'd like to keep the same materia.

From Bayohne's description, the option to keep the weapon and destroy the materia is present, but not the reverse.
