Dimension Door vs. Prismatic Sphere & Wall

[Lifat]

Hi all. I've been running my head against the proverbial wall in coming up with an answer to my rules question(s)...
Could I Dimension Door to the inside/other side of a Prismatic Sphere and/or wall.

Here is what I've come up with so far:

Dimension Door is Conjuration (Teleportation), meaning that teleportation is instantaneous travel through the Astral Plane. Anything that blocks astral travel also blocks teleportation.

From this I infer that Dimension Door would skip into the astral plane and make you pop up in designated target area.

Prismatic Wall is an abjuration spell that is not a force effect. It does not exist in or effect the ethereal or astral plane. That means that as long as you are on the astral plane you should be able to move through the wall as though it does not exist, including all its effects that stop spells, and pop up on the other side with no issue, as far as I can tell. I'm open to be corrected if I'm wrong, but I want it to be rules based and not opinion based.

Prismatic Sphere has the same limitation as the Prismatic Wall, however Prismatic Sphere is a solid sphere and not a shell and thus also exists in the area that you would presumably want to arrive at. My question then becomes, what happens? Did the Prismatic Sphere that stops all spells prevent the reentry into the material plane from the Astral plane and thus you would get shunted to the outside of the Prismatic Sphere or did you pop up inside the sphere and now get subjected to each layer in order?

Thank you in advance.
PS. I know that there is another discussion about it but it was in 2012 and would thus be a necro. Besides, the discussion devolved into opinions that was not rooted in rules.

I don't think Prismatic Sphere is a solid sphere, it's a sphere-shaped wall (a hollow globe).

And yes, you can teleport to the other side of a wall. Should work for either.

I agree the prismatic spells are powerful but unless there's a rule I missed they only affect the plane your on. So unless your in the astral plane when you cast them dimension door should work to bypass them.

1) Start in Material Plane.
2) Move to Astral.
3) Move to new location.
4) Return to Material Plane.

The astral plane doesn't have a one-to-one mapping of locations with the material plane. As far as a teleport is concerned you disappear from the location outside the sphere, reappear inside it and never touch the barrier between.
