Is there anything that makes becoming ethereal last longer? I've got all three words for the shout but the effect only lasts around a minute.

I want to be ethereal until i break the effect myself by interacting with the world. Is it possible?

An enchanted ring or necklace perhaps?

I don't think there any enchanted rings or necklaces that effect shouts in that way.

Really? Thats a shame

The amulet of Talos does something for shouts that just makes the cooldown last less longer, but I don't know if it does entirely... I don't bother with dragons or shouts or dragonborns outside of my Argonian.

Thanks. I think i have that amulet so i shall check it out.

Lol three words is 1 minute? And you aren't satisfied?!

I think there is also a glitch using the amulet of talos that lets you spam shouts nonstop. YouTube should have more information on that

If you meditate the path of spirit with Paarthurnax, it should boost this particular shout.

There's no way to become etheral for an unlimited amount of time as far as I'm aware.

Amulet of Talos and the shrines maybe.But maybe they only decrease the timer.

If you could unenchant amulet of talos you could use it nonstop no cooldown but the game doesn't let you.
