Eisen grabbed the crystal and slowly split it up into two parts before pushing his mana into one of the halves again. The small ball that was created was half the size of the one from the regular one, so Eisen managed to confirm that it was really properly working like it was supposed to. The gem itself now had the effect of creating a rock sphere. The old man merged the two halves together, and then carved an effect-enhancing three-dimensional enchantment into the mana crystal, without specifying which effect it is enhancing.After that, Eisen poured his mana into the mana crystal and a ball that was roughly two to three times the size of the base effect's appeared in front of the old man.
