Materia System

[Amineri]

I kinda can see where the lore for this is going to come from.

When an item is crafted the Crystals used to create the item leave a bit of the essence in the item that created it.
As a user uses this equipment in combat it slowly draws energy into itself.
After the weapon has absorbed enough energy it becomes catalytic.
Now it can be processed and converted into a Materia Orb.

I think this is where the "affection" concept comes from. You essentially personally invest yourself and your energy into the item.

However, I still am unhappy that everyone assumes that this system is 'combat-only'. Why can't a miner invest affection into a mining pick and then convert said pick into materia?
