Infusing the Luminasiel weapon with essences of evil thoughts and actions gives it power. But for that power to be wielded by you, rather than upon you, the weapon must then be purified.

Go to Solomon in Kamena Development District. He'll tell you about the next step.

Player: Accept.

A Luminasiel weapon? Then you're here for the Light of Innocence.

It's a very rare material that is sometimes created while making Noble Aureoles with DP. If you're serious, you'll need to buy the design from Safadorn. Good luck.

Collect a sufficient amount of Light of Innocence, then bring them to me.

Player: "Thank you."

Player. Welcome back.

Were you able to create the Light of Innocence?

Player: "I have it right here."

Amazing! I'm sure you went to a lot of trouble to make this.

I wish I could tell you that was the last thing needed for the Luminasiel weapon, but there's still more components needed.

You'll have to go back to Kahrun again.
