Eisen grabbed everything that he needed for the creation of this special mechanism. An in the end, it didn't really require anything all too special beside just some crystals that he could enchant.
He combined a few crystals together that all worked together with each other to create something even better than before. If the gem that Eisen used for the special brush in Trygan's realm was an 'Artist's Gem', this was a 'Craftsman's Gem'.
Eisen used this as a base for the enchantment and inscription. First things first, he grabbed a small cube that he kept something very special in. It was the soul of a monster that had gained a very powerful craftsman-evolution. It was basically a master-craftsman in itself. Somehow, Eisen had come across a group of these that were all working with each other. He would save the 'leader' of these monsters for himself for an item, but he chose one of the regular souls for this item.
