One of the galaxy's legendary Seven-Star Swords. Its sorrowful blade bears the sins of the galaxy. Also known as Sword of frozen fate. It's a main weapon for Jaster. Tips about the blueprint can be obtained from Agassimo and Misanna who are both at Rosa. Teleport to the Spaceport then return towards the Plaza. By the middle (large open area) go left. Talk to Agassimo under the tree. Use the nearby transporter and warp to the church (Salgin). Go inside and speak to Mesinna. Once manufactured this item is added in your Inventory. You can obtain the blueprint by chapter 7, but the earliest time you can develop this sword is by chapter 8, when you can get an Edensia.
