the trick is to pick up a follower, i prefer to bring in sivir, then tell her to attack the boss ignoring the little ones, you can clear them out if you have to, but her spell sheild will make her avoid most of the artillery, just need to watch out for the blue wraith spawn wave, and when kog'maw bursts, that **** hurts
*edit* i just remembered, you need to have a regrowth pendant from the last level, or have some way to survive death, or else you can't regenerate your wounds before the chain reaction finish
i managed to get through with olaf, he seems to work really well, he has a boost to nearly every enemy, besides mordeakaiser, that metal just dings up his axe's, but i managed to get through with some luck and lightning bolts, as it is conducted by metal
