Waking from a bad dream

BLM:72 WHM:54 SMN:36 THF:70 WAR:56 RNG:36

Well it's morning here in Jeuno and two very significant things have happened since two days ago:
1) Last night, I got my tail end handed to me by Diabolos Prime
2) This morning, I got my last whisper needed to trigger the Fenrir fight.

Diabolos uses a lot of Sleepga II and Nightmare. Now Nightmare seems to be more of an ability where Sleepga II is a spell. Attacking from a far off square makes it easy to just cure off the the melees if he throws out Sleepga II. But Nightmare not only sleeps the melees but sleeps everyone. After they are asleep, usu the tank dies cuz noone can cure him AND he stays asleep! Poison potions are also no use against Nightmare.

He also uses Cacodemon which is an AOE Curse spell. You remember how it limits your mp and lasts forever? He also uses Nether Blast much like you see people that have the avatar use it. He hits for like 200 or so to a 75 NIN, just as a regular hit.

Now I am not one to be pessimistic but from the way Diabolos was tossing his abilities this way and that, it seemed almost unlikely that a regular party setup could beat him. His "Nightmare" ability NEEDED to be stunned and it was very hard to do. We were using a NIN DRG RNG WHM BLM BLM. After the fight and basically not being able to Stun him successfully even once, someone in the linkshell told me that you had to "fresh" Stun him. Using a macro, which I had become accustomed to, was slower they said. The other BLM was also not able to stun him using his macro either. I didn't think it possible frankly and the one DRG who was lucky to be there imo, was the loudest to complain that we weren't stunning him.

After dying 4 times, he's lucky I didn't accept that invite from the other party that was already there.
