You will need to talk to your town's leader after obtaining this lengthy mission (from the gate guard) but ALL towns will eventually direct you to their embassy in Ru'lude Gardens.
To prepare for this hard mission buy a map of Qufim in Low Jeuno, getting 2 parties to make an alliance if you are too low level, and finish "The Antique Collector" quest in Port Jeuno for the Map of Delkfutt's Tower. At least two people should have the Map of Delkfutt's Tower by trading a Kaiser Blade (drops from Weapons in Qufim) to Imasuke.
When ready head to Delkfutt's Tower in Qufim. There are 10 floors in the Tower divided in 3 parts linked by teleport. Make sure your magic users are aware that Magic Pots/Elements go aggressive when you cast!
After a lengthy climb (will take at least 1.5 hours), fight the NM giant Porphyrion. It will drop 6 Delkfutt keys each, so you will have to wait for it to respawn (10 mins).
When the whole alliance has a key, trade it to the elevator (H-8). Finally head to the tunnel to the east walk down a 9 flights of stairs down to the first floor. You will be in the basement. There will be 3 exits for which are based on allegiance (M-7, M-8, L-9). In each one is the Ambassador.
Go back to your Embassy in Ru'lude Gardens to receive your reward!
The are for stairs/teleports, and their rough cardinal direction.
1st Floor: E-6 (NW) 2nd Floor: I-9 (SE, deadend at H-9, so go east first) 3rd Floor: G-6 (or J-8, but I think that might be one way only) 4th Floor: I-6 (NE, deadends at G-7, H-9, J-9) 5th Floor: H-9 (S, deadend at I-10, so go west first) 6th Floor: J-10 (SE) 7th Floor: F-6 (NW) 8th Floor (1st time): I-6 (NE) 9th Floor (1st time): I-9 (SE, this sends you back to 8th floor) 8th Floor (2nd time): F-9 -> 9th Floor 9th Floor (2nd time): F-6 -> 10th Floor 10th Floor: Fight Mimas at H-7 and Porphyrion at H-8 for keys, then use elevator at H-8 (Note: beware of elementals that spawn under certain weather)
Basement: for ambassadors (use same key as elevator), M-7 Windurst, M-8 San d'Oria, L-9 Bastok, then use F-8 to go back to 1st floor and exit.
