Waking the Beast/Strategies

6/17/22 - Won with 7 people
Setup was War, Sam, Drk, Nin, Brd, Rdm and a Whm/nin in the outside party. We forgot Treasure Hunter but any of the DD could be changed to Thf really. 
None of the mobs are particularly evasive, it is recommended to have a MDT set to handle Astral Flows as it makes them not scary at all.
We fought Carbuncle down to 75% and he spawned 1 avatar like normal, easy to kill.
We fought Carbuncle down to 50% and he spawned 2 avatars, we had the Whm/nin kite one while we killed the other.
We fought Carbuncle down to 25% and he spawned 3 avatars, we had the Sam take one, the Whm take one, and focused the other.
After those 3 avatars are defeated the 5 Carbuncle Primes spawned, which each DD took one and spread to the corners so as to not overlap Astral Flows. The Carbuncles are easy enough to burst down from 25% with 2 hours or just fight straight up, not that scary especially with SV Marchx2 for shadow recast. 
No drops, who forgot the TH!?
