This one is the toughest of the 3 *duh*. for 75's it's really easy. I fought it as a 52 DRK/RDM with a 75 RDM, 65 PLD, and a 43 WAR (was a friend I invited along for fun). even then the fight took a few mins.
I do not believe that this mob is level 54, we fought it with a lvl 73 RDM 68 BRD 60 BLM and 51 DRK and got experience points. It was also an extremely long fight.
nah this guy wasn't hard at all. Me and a 66 rdm named skynet duo'd this thing and the other two easy. He was 66rdm/33drk and i was 60rdm/nin (forgot lvl at the time) so basically we buffed up and got 300tp we would enfeeble them go for the kill with spirit within, but only took half hp from this guy, so just meleed to death, but the cool thing was that he casted freeze, burst and some other AM spells to the 66rdm and w/o stoneskin or phalanx it only did a max of 55 dmg. so basically not worrying about the magic just kept hitting him. ya so basically hes a total wimp
