materia growth

[Viladin]

So, in order to gain exp, a materia hast to be in something equip to you. That's easy for armor and melee/ranged weapons, but how does it work for thrown weapons? if i have a dagger with materia in it, and I throw it at an enemy, does the materia gain exp.

I suppose what I'm asking is can materia gain exp for being apart of the battle, or is it simply the materia equip at the end/beginning of combat, Or is that just something for the gm to decide?

Yes, as long as you had it equipped at beginning of combat, it gains MXP.
