So some context to this. I'm starting a new campaign in which the characters, regardless of their own supernatural power, are generally ignorant of the supernatural world. They may have great abilities, they may fear their own abilities, but goblins and demons and warlocks and flying spaghetti monsters are all things of myth to them. Suffice it to say that illusion is gonna get broken by the end of the first adventure.
One of the beasts they'll be fighting is a creature with a damage barrier. Now as the rules for monster creation state, the creature's damage barrier doesn't protect against attacks which can damage energy. So that begs the question of exactly what deal damage to energy? Some abilities of course are very explicit about it, such as the Aura Extension ki power. But what about a pyrotechnic psychic ability, like Immolate.. or a necromancy spell like Death Beam? Both are clearly supernatural powers, but will do they count as powers that damage energy (Death beam hits the Energy AT, so I'd think that would be the case, but I'm not sure)
