Blinking VS See Invisible & True Seeing?

[Arravis]

Etherealness mentions "See invisibility and true seeing reveal ethereal creatures."

Which would seem to answer the question at hand.

On Hypersmurf's point:
To me, it does seem to be, to think of it practicaly, that you ARE in both planes. Or at least some of you is. Etherealness seems to give you a list of conditions which you are under on the prime (invisible, inaudible, insubstantial, and scentless), but still able to be affected by a few specific things. If you aren't in the prime at all, why would it give you invisibility and such in the prime? If you aren't there, why would it matter?

No, it doesn't. It says that you are invisible (etc) to creatures on the Material Plane.

If you're in one room, and I'm in the next room, and there's soundproofing in between, we can say that I'm inaudible and invisible to you. Does that mean I'm in the same room as you?

If you aren't in the prime at all, why would it give you invisibility and such in the prime?

It doesn't. You don't 'gain invisibility'; you simply are invisible and inaudible to those creatures. It's not a magical invisibility, it's just an 'unable to be seen'.

If you aren't there, why would it matter?

Because an Ethereal creature can see and hear (to an extent) things on the Material plane, so it's necessary to explain that the reverse is not true.

If you aren't there, why would it matter?

Because the two planes are coterminal, [Force] effects and abjurations extend onto both planes. It's important to know where someone in the ethereal plane is in relation to the prime material for such situations. They are not, however, simply invisible, inaudible and scentless.

Assuming they originate on the Material.

Oh, right. Meant that.

 

[Arravis]

Thanks for the explanations guys, clears that up nicely I think .

I had an evil plan once - imagine a party who are exploring a mist filled dungeon. One of the doorways is a portal to the ethereal plane and the party unknowingly walk through that. They come across the powerful wizard who can see them on the ethereal (see invisibility) and who starts blasting away at them with magic missile (force effect goes onto the ethereal) while the party don't have any means for affecting him - and they may not realise that they are actually ethereal, they might think that HE is a special kind of ethereal...

Struck me as a wicked sort of trap

 

[Infiniti2000]

That is indeed a nice trap. Make sure the 'door', whatever it is, shuts behind them. Or, have the wizard start things off with a wall of force across the 'door' and have his room shielded in something like walls of force or a giant (widened?) permanent forcecage or something.
