Where in the world do you get these things from? I can't even use a spell for my class because it requires them to use yet I don't see them in ANY vendor ANYWHERE. The only place I see them is in one player's private shop that is selling 26k of them along with 6-10k each of the A/B/D grades all bundled together for a whole 2 BILLION that can't be purchased separately from the other types. I don't even see them in the L2 Coin or L2 Store for sale. Really frustrated in this game right about now because of this.
