**SPOILERS** (maybe)
Question: Does Kelvos's protective aura benefit the PCs? It provides a +4 AC and resistance bonus to anyone within 20 ft against attacks by good creatures, and technically, Kelvos is a good creature...as are the Angels of the Worm. Are the Angels of the Worm affected by Kelvos's gaze? Does the Angel of the Worms's magic circle against good apply to their own attacks since they are also technically good?

I double checked, and this is how it breaks down:
Since Kelvos is Corrupted (as per the template from BoVD, I think), "he retains his good subtype (and does not gain the evil subtype), but many of his abilities have changed focus..." His Protective Aura says it protects against attacks made by "good" creatures...Hmm. The way I read it is...the protective aura works to his and his allies' benefit, but not to the PCs. It would be as if he didn't possess the "good" subtype at all. Same deal with the Angel of the Worms' magic circle, in my opinion. Confusing, I know.For the gaze, check the Monster Manual definition of "gaze". It says, "Allies of a creature with a gaze attack...are considered to be averting their eyes from the creature with the gaze attack, and have a 50% chance to not need to make a saving throw against the gaze attack each round." Therefore, I would say, yes, the Angels would be effected in the aforementioned fashion.
