Yes, just go back and exit to Thousand Cuts and then go back into Terra's area. You need to use Eridium over and over though, but he drops tons of it. --- ________________________ Xbox360 GT: PrisonedJASON
I'm sure once you turn in the mission that you have to kill him, you should be able to go in and out of his lair once you kill and he keeps spawning, only downside is you have to give up 4 eridium but he drops some once you kill him. Hope this helps.
Edit: you both beat me to it. --- GT: Dark Guardian88 3DS FC: 1375-7986-1634
