Dike, Kaisinel's fourth Agent, explained that you would need a Daevanion Weapon if you want to become Kaisinel's Protector. She advised you to find Ephaion. Ephaion said that you need a Loyalty Engraving Design to craft a Daevanion Weapon Prototype. You gave Ephaion the materials for the Loyalty Engraving Design. Ephaion reminded you how important it is to remain loyal to your comrades-in-arms and the Lord. Ephaion asked you to defend the Elyos regions in Balaurea. You fought in Balaurea. You then received the Daevanion Weapon Prototype from Ephaion. You took the Daevanion Weapon Prototype to Dike. She performed a ritual to finish the Daevanion Weapon.
