Yesterday, my friends and I, attempted to fight Fenrir Prime. It was quite a success. Our party consisted of PLD, SAM, SAM, BLM, BLM, and RDN/DRK. For the first half of Fenrir HP, we fought him steadly, RDM/DRK and the 2 BLM kept the PLD alive with multiple Cures and at about 55-60%, RDM/DRK Converted started Chainspell/Stun, and the SAM's did their 2 hours. RDM/DRK only had time to cast Stun 4 times, by that time Fenrir was defeated.
My RL brother, which was one of the SAM's, added all the damage he did, and counted a total of 6058dmg points against Fenrir Prime. We looked on Wiki and Alla to find out Fenir Primes total HP. We want to compare his damage dealing to the total HP.
So if anyone knows how much HP Fenrir Prime has, please let me know.
