How about Holy Smite? That line of spells lists different damage & effects for neutral vs. opposed alignments.
And it's where we come to the interpretation issue.
Should someone with Aligned Planar Mastery be immune to a Corrupted Fireball, or Death Knell, or Contagion, simply because the spell has an [Evil] descriptor? Creatures who are actually evil aren't immune to those spells.
... hmm. You know, I think I'm actually basing my argument on the wrong clause. "
spells and abilities that harm those of the opposite alignment don’t affect you" is what's giving the problem, but the next sentence isn't as ambiguous:
You have the dominant alignment of the plane with regard to magic.
So if 'the plane' is evil, then with regard to magic, you're evil... and so Blasphemy doesn't consider you non-evil, and you're safe. Corrupted Fireball and Summoned Monsters, on the other hand, don't care what your alignment is with regard to magic.
My next question is how the mechanics of Aligned Planar Mastery work. Do you choose a plane at the time you gain the ability? Do you choose a plane at any time during your turn? Can you choose a plane during someone else's turn? Can you mimic multiple planes simultaneously?
If the Demon casts Blasphemy, and then my buddy the cleric casts Holy Smite, can I avoid the effects of both by mimicking an evil plane and then a good plane, even if my turn doesn't fall in between? What if I'm stunned or unconscious - can I still switch?
It almost feels as though the intention of Aligned Planar Mastery is similar to Weightless Planar Mastery - unlike most of them, Weightless specifies that the speed bonus only applies on the weightless planes. It
feels like Aligned Planar Mastery is supposed to draw its definition from the plane you're currently occupying, which removes all the issues.
