agreed, holan is nasty but if your just leveling there is no reason to kill anything past Oceania. If im not mistaken, id have to run it again but the only boss that needs to be killed is the first one. Then just make sure to kill the door mini bosses and then reset and repeat. The only reason to kill the bosses is for the mats. If you have to kill bosses then a lvl 134 bm,ea,wiz, wb, wf, cleric etc can kill all of them except for holan he cant be solo'd till 140+ or he can but you have to be a wb fully decked out in g16 gear.
For 130-140 your hubby should be in full g16 gear and running the tt's, just make sure he uses his stun lots and sutras.
