Dungeon 90+ bug?

I continue fail for the bug... now I modified only the cell range to 0 and nothing more. I tried to modify the unpaked file Creature of data.pak and I fail. I tried to modify the data.pak with win hex and I fail. I have a friend AK that can finish the dungeon without bug. I gave him my account and he fail... It looks like a problem of my character... If one of you is a bagi and can finish the dungeon without bug please tell me which skill do you use.

I finally solved this problem. Knock back bagi skill are bugged so you have about 0.1% rate to make a mob disappear with a knock back. And if a mob disappear the doungeon counter will miss some mobs at the end of the round. So I can't use Spirit Shout and Carnage. The only AOE I can use are: Dead Spark, Outrage, Tornado, Earthquake, Chain burst, Shock wave and Hard Blow(last hit is aoe). At lvl 99 I can finish C dungeon even if it is not easy(I'm close to str build).

crevice a with 2 level 100 hunter is no problem easy done 4 times in row ;)

just stay together. doing aoe all time. in the middle near a wall.
