@Siviard Mnk and Whm duo this was. I'm sure if you get claim you'll have no trouble bringing him down on SCH. Along with Tiamat, this was on my "things to kill before i quit FFxi" list. Good luck and happy hunting :-)
I'm assuming SCH and MNK duo? Regardless, well done! I plan a solo attempt on my SCH if I could ever find Jormungand up on Shiva. For some reason or another Jorm is camped. *shrug*
