''At Level 120, speak to Grendel the Really Old. He will send you to see Gritto of Leafre. The job instructor will instruct you to return the Heroic Star and Heroic Pentagon. They are dropped by Manon and Griffey, or obtained through buying the Secret Letter of Spell from Vega and giving it to Chief Tatamo of Leafre. Either way, return the items to Gritto and she will complete your journey as a Priest and advance you to Bishop! ''
