Infiltrate Davoi 3-1
Client: Gate Guard
Reward: N/A
Skippable: No
Items Needed: None
Talk to the gate guard to pick up this mission. If you don't see this mission available for you to do then you may need to boost your rank bar up by trading crystals to the guard that cast signet on you or do the previous repeated missions over again to boost your rank bar.

After accepting this mission, you have to talk to Prince Trion in his chambers. He'll tell you to retrieve a report from a soldier in Davio.

Inside Davio, head across the bridge at H-7 and you will find a soldier, Quemaricond walking back and worth. Talk to the soldier to get the report and then head back to talk to Prince Trion. When all this is done, talk to the gate guard to complete the mission. Depending on your level, you may need to invisible yourself pass the Orcs before you can find the right time to drop invisible to talk to Quemaricond.

 
 
The Crystal Spring 3-2
Client: Gate Guard
Reward: N/A
Skippable: Yes
Items Needed: Crystal Bass
Talk to the gate guard to pick up this mission. If you don't see this mission available for you to do then you may need to boost your rank bar up by trading crystals to the guard that cast signet on you or do the previous repeated missions over again to boost your rank bar.

If you see this mission and don't want to do it then continue to trade crystals to the guard that cast signet till your Rank bar is high enough that the next mission after this one is available for you to do.

If you decide to take this mission, the gate guard will simply ask you to get him a Crystal Bass fish. There are two ways to do this. The first and easy way is to just buy the fish at Auction House. The last way to do it is head over to Jugner Forest to J-9 where there is a spring and fish for the Crystal Bass, assuming if your fishing skill is high enough. Once you have the fish trade it to the gate guard and head over to Chateau D' Oraguille and talk to Curilla to get a few cut scenes to complete the mission.

 
 
Appointment to Jeuno 3-3
Client: Gate Guard
Reward: Rank 4 & 5000 gil
Skippable: No
Items Needed: Delkfutt Key
Talk to the gate guard to pick up this mission. If you don't see this mission available for you to do then you may need to boost your rank bar up by trading crystals to the guard that cast signet on you or do the previous repeated missions over again to boost your rank bar.

After talking to the gate guard, talk to Halver in Chateau D' Oraguille and he'll send you to Jueno. Make your way to Jueno and head to Ru'Lude Gardens and talk to Nelcabrit in the San D'Oria Embassy. Now you need to find the Embassador who just happens to be in Delkfutt Tower. There are two options now as you'll need to make your way up to the 10th floor of the tower and get a Delkfutt Key from a NM then use the key to make your way down to the lower level to find the Ambassador. The first open is to the a party together of level 40 or get an alliance together of level 30 and make your way to the top. The second and cheap way is to get some high level help. A level 50+ can solo this part and escort you just fine.

Whether you have a party/alliance or a high level player escorting you, make your way to the Delkfutt Tower in Qufim. If you don't have a map then it's a good idea to complete the "The Antique Collector" quest in Port Jueno to recieve a map of Delkfutt's Tower. Here's how to make it from the first floor of the tower to the 10th floor.

1st Floor: E-6
2nd Floor: I-9
3rd Floor: G-6
4th Floor: I-6
5th Floor: H-9
6th Floor: J-10
7th Floor: F-6
8th Floor: I-6
9th Floor: I-9
8th Floor: F-9
9th Floor: F-6
10th Floor: H-8

At the 10th floor at H-8, you'll need to kill the NM, Porphyrion. He'll drop the Delkfutt Key. Use the key on the Elevator nearby and make your way to the underground floor. Head over to M-8 and use your key and talk to the ambassador. Once that's done, make your way back to San D'Oria Embassy and talk to Nelcabrit and then find the ambassador again in Ru'Lude Gardens to complete the mission.
