Suffer!
...seriously, I beat this thing my first run through with a PUG. Just learn when to eat the fruit and where to stand and you're golden (or not golden, as it where). Google a video if you need to see what to do. Explain it to whatever people that are in your group if they've never done it. As long as you explain in clearly and in a non-condescending manner, and the other people are not secretly cabbages, it should be only a little tough. If you still can't beat it and everyone's geared properly (which shouldn't be a problem), and you realize that the gold liquid is not for bathing...well...I don't know what to tell you. Play better? That's not meant to be condescending, I just don't know what else to suggest, it -really- isn't that bad.
