Medusa Sheild is killing blind and undead, bug?

[Kristoffer O]

Ghosts don't turn to stone, you know. They turn into glow-in-the-dark-jello. It is not as hard as stone, but it tastes good. Many petrified/jellyfied ghosts have found themselves eaten by young menacing humans with lots of make-up and dark robes.

It's a magic spell... the maggots that come into being have been created through magic and thus are magical themselves and can hurt and devour magical beings. Even if part or all of their victims' makeup is ethereal, I don't see how they can have an immunity to it. It says right in the description that ethereal undead without bodies have a good chance to resist, and that's more than enough already.

I thought Maggots specifically had a hard time affecting ethereal undead (like mundane weapons). At least, it says so in the description.

Is that not the case?

[Renojustin]

That's what I just said.
