Can someone help me beat Krom?

If you are playing as lilith then branch into the controller tree and max out mind games skill. Now equip a high fire rate/extended magazine SMG/Sniper and watch as all enemies and their bullets move like snails (Yes this affects Krom's rocket launcher). Pair this with phasewalk and you can effectively spray enemies and blitz past them and/or phasewalk further into the canyon and finally upto krom and cause major mayhem with your SMG. If all fails get yourself a X2 or X3 zoom sniper with corrosive/incendiary X3/4 element and in between krom's rocket burts pop out from the huge boulder at the canyon entrance to take pop shots until his health drops and he bites the bullet.
