Are you sure there isn't a fire attack that occurs after the earth attack, lch? In the description, you're first exposed to an earthquake, which is presumably AP mundane damage, then exposed to meteors, which is presumably AP fire damage. The fire attack would explain why etherealness doesn't help, but a Fire Plate does.
Every seen!
fyi - Armageddon is actually a location, not an event. The cataclysmic battle between good & evil that decides the fate of - and signals the end of - the world occurs at Armageddon. "Apocalypse" is probably a better title for a world shattering Wish, but not great. "Poor CO2 Management" or "Global Stupidity" may be better.
