After finishing the prototype for the Yin-Blade, Eisen moved on to the next item. He wasn't actually able to test the Yin-Blade out, but judging from the name of the item that was display in the notification before he was pulled out of his Deep Visualization, 'Size-Changing Greatsword', Eisen figured that it should work out at least somewhat. He was able to re-do enchantments as much as he wanted anyway, so he would try these enchantments out with a few other items before placing them onto the blade, and then it would probably work out just fine after Eisen could figure out in what ways they were issues with what Eisen was planning. Either way, now that he created the item in his Deep Visualization state already, the size-changing effect would probably just end up stronger as well.
