Full Moon Fountain.
Go to the magic tower in the Horutoto Ruins in West Sarutabaruta. Once you check the door in the corner room, "4 Jack of ¨C" pop up. It'll say "impossible to gauge".
Jack's jobs are :
Cup = White Mage
Baton = Black Mage
Coin = Red Mage
Sword = Paladin
"Ten of --" will link later, so clearing them first is recommended. Party of 10 players around 60 is recommended. Once you go back to Orastery, you'll be told to go to the underground of center tower. Go to Troimrai F-8 to complete the mission. ¡¡
M6-2
Saintly Invitation.
Recommended a party of level 60.
After receiving "The Saint's Invitation" from Star-Sibyl, go to the Balga's Dais. Only players who have received this mission or those who have completed it can carry out the first part (foreigners can't help), and anyone can help the second part if they want to. There are 4 NMs; Chaa Paqa the Profound (Summoner), Nuu Kofu the Gentle (White Mage), Juu Zeni the Poisonmist (Ninja), and Buu Xolo the Bloodfaced (Samurai). There are Yagudo Elementals also. Each NM uses its 2 hour job ability, and be warned of the Summoner and Ninja's ability. After defeating them, you will receive a "Proof of the Balga's Dais conquerors". Then, go to the top floor of Castle Oztroja. Defeat Yagudo Flagellant to obtain a Judgement Key (one will do). Then go to the door in H-8 to use the key and enter. Talk to Kaa Toru the Just, and receive "Saint's Oath" and "Ashura's Beads (Level 54/All jobs/Def 1/ Str1, Dex1, Vit1, Agil1)". Go back to Heaven's Tower to report to Star-Sibyl. /rank7
