I gotta agree that this is one tough battle. And the arrows of holding didn't do to much for me on the first time through it. I ditched them all together the second time through and did much better using spells instead.

Lots of summoned creatures throughout to provide a shield between my chars and the harpies. Lots of area affect spells (web, entangle, cloudkill, spike stones, death fog, etc) concentrated on where I managed to pin the harpies. War chant of the sith for the healing.

I managed to come through it with all 6 of my chars alive the second time, though my fighter/druid at one point was down to 1 (!) hp. That was a scare. I can see why it would take a few run throughs for most tho.
