Me and 3 of my friends did this 3x yesterday.
we had a WAR/THF, WHM/BLM, MNK/THF and DRG/WAR<-me
Only used Protect I and Shell I, kabobs and juices
Me and the MNK would alternate to go in.
First time the MNK went in with the WAR and the WHM and they got wooped (WHM died before using Bene)
2nd Time i went in. Me and the WAR Renkei'ed as much as we could (Had a low hit % on them) and the WHM did'nt have to use Bene until only Colo-Colo was left, it was a close call but we made it!
The last time we got wooped again (w/o 2hr's)
2hr are a must in this fight!
