Transmutation - What have you been coming out with, what combination?

[Akujin]

I'm stuck at work...what are you talking about?

2.25 included Materia Transmutation - basically you're supposed to take 5 pieces of materia, give them to the goblin Mutamix, he'll then give you a single piece of different materia. Could be good, could be bad.

It's also why the market wards are going crazy with prices for otherwise horrible materia at the moment.
