Standing on the top level and just throwing up Dome of Protection basically kept me immune to any sort of damage for the entire fight. It doesn't matter how many of those stupid blobs jumped up onto the platform next to me. I smashed their faces and just regenerated all my magic armor every turn from the Dome.

As for the larger blobs, used my ranger to pick them off from high ground, plus throwing knife from my rogue, and if I wanted to speed things along I just phoenix dive Red Prince down there to finish one of them off, and then have my wizard cast teleport on him to bring him back up to my dome of protection.

I found this particular fight to be insanely easy *shrug*
