killed him as 57war/nin and 54rdm/whm (me) for my whm ^^
marchelute did 10 dimensional deaths (some took 90hp some 200hp, but no more than 220hp), ate my debuffs with ease.
I had to use convert once, cuz marchelute is pretty fast and war didn't have much time to recast his utsu, and I was curing him all the time; spamming cure III, few times cure IV + debuffs, few elementals and some buffs that went off during the fight took lots of mp ^^;;
it took a bit of time... but there wasn't any scary situation, so it's ok ^^
and my whm has AF1 done ^^
