I did... I finished him both on level 50 and 34...
He wasn't that hard? or maybe I'm just sick at dodging :3
He was awesome though. his tentacles made me level a few times the first time I beat him.
(also, I was using the same character as you, zero, only I was able to kill him with that critical hit skill. you know? the one where your able to get a stack of 999 times 5% extra damage and 6% extra critical damage with snipers? I used the quickest sniper I could get and aim for his eyes. hadda get a lot of ammo from his tentacles and it took a while to get such a height in the stacks. Actually, I'm probably a very lucky bastard to have been able to do that.)
I later found a exploit of sorts, but it takes hells 'a time to use it properly.
Do you remember "the law"? it was a gun, and in combination with "order", as shield, every melee attack would heal you. Use that with zero after having beat the game (preferably twice,
as your damage will be high, as will your health) and you can get the achievement "heal please". After having beat the game, you can get those over and over again, so doing that and
getting "heal please" gives you badass points over and over to buff you up to proportions far beyond normal. only, it takes TOO LONG. not only to get the points in in the first place, but
also to get the points. but I guess this is the quickest way, unless you'd like to shoot yourself with a rocket and buy the health over and over...
But it's fun playing online too. Though I personally like to fool around now that I have quite a lot of spent badass points, so I'm much stronger than the others ^^
I once was a level 9 and rivalled a level 16 in damage... t'was fun xD - he must've had a real cheap gun on him or something..
now that was more text than I imagined typing ¦:I
