I know I can't enter the Tiny Hut while being in the Border Ethereal but can I leave it? I.e. I'm in a Tiny Hut (someone else casted it) and cast Etherealness. Can I leave and observe the material plane outside of the hut or will the magical force block me from doing so?
I'm asking because the Tiny Hut spell specifies that
Creatures and objects within the dome when you cast this spell can move through it freely
but also that
A 10-foot-radius immobile dome of force springs into existence…
which implies magical force IMO and DMG says that
A traveler on the Ethereal Plane is invisible and utterly silent to someone on the overlapped plane, and solid objects on the overlapped plane don't hamper the movement of a creature in the Border Ethereal. The exceptions are certain magical effects (including anything made of magical force) and living beings.
So which of these takes precedence? Can the caster of Etherealness (who was inside at the time of casting of the Tiny Hut) move freely through the barrier even while she/he is in the Border Ethereal or not?
Best Answer
Yes, because everything works per spell description
While true that Leomund's Tiny Hut block ethereal travel because of being made from
, the rest of spell description makes it clear:
You are inside when spell is cast. If etherealness is not cast through it, and is not, because of range self, you are free to leave tiny hut, walk around border ethereal, come back and nothing happens. Although you must be on a plane where you can succesfully cast Etherealness, otherwise nothing happens.
