ethereal visage 20/magic?

[Meatiest]

Hi all, I was hoping someone could tell me. The wiki says 20/adamantine, and the IG spell description says 20/magic, which one is accurate? 20/magic means most high level creatures will pierce this DR right? Thank you!

ghostly and etheral visage should both be addy, magic meant anything +1 or higher made them useless

[Thaelis]

Could it be made 20/+3 instead?

That would kinda make more logical sense. I guess it'd be a little weaker, but maybe it would work in combo with Stoneskin so that only +3 adamantine could bypass both?

/+magic has only been done on mobs/bosses as far as i know, so its doubtful

all player usable DR should all be metals, but unless you are a warlock you really dont have many options for layering protection
