What happened this time? Hmmm, so you need to make the polearm's gem yourself? My goodness, that weapon definitely has an attitude, but you can't ignore its pleas either....
4032312 is probably a gem that has the power to exponentially expand the weapon's powers, which means you'll have to cater to its wishes and make it a 4032312 as it wishes.
What? You don't know how? That's easy! This is directly related to you, you have a specific target, and you even have a specific wish. That means you can use the Mirror of Desire! Go ahead!
Accept
You remember where the Mirror of Desire is, right? Head west, out of town, until you reach a dead end near the ice cliff, inside 140030000. There, your task is to find out how to make a 4032312, and then make it. The Maker Skill should come in handy for you.
Decline
…Eh? What is it? Are there side effects to using the Mirror of Desire? Or do you really not like anything that seems to have to do with the occult? I refuse to put up with whiners!
