[RPG] Is casting Create Demiplane (Any) from the Astral Plane a valid way to get a permanent demi-plane

I was cruising through high level spells and noticed the Create Demi-plane serie. All of them are nice but pretty intensive on the maintenance part, Day/lvl is nice but still… you don't always have a day or two to waste on recasting the spell(s) while adventuring.

The permanency alternative is horrendously expansive and we all know that it can be dispelled easily by any spellcaster you antagonized enough (The list is likely to be pretty damn long by the time you get to this level of power). Losing thousands of GP on a single spell is pretty painfull.

Then I remembered reading about Planar Traits…

Timeless for example (Emphasize mine):

Timeless: On planes with this trait, time still passes, but the
effects of time are diminished. How the timeless trait affects certain
activities or conditions such as hunger, thirst, aging, the effects of
poison, and healing varies from plane to plane. The danger of a
timeless plane is that once an individual leaves such a plane for one
where time flows normally, conditions such as hunger and aging occur
retroactively. If a plane is timeless with respect to magic, any spell
cast with a noninstantaneous duration is permanent until dispelled.

It made *Tilt* in my head.

What if I shift to the Astral plane which happen to be Timeless then cast create Demiplan ? Do I have a cheap permanency-ed Demi-plan?

Best Answer

From the Pathfinder SRD entry on the Astral Plane:

Timeless: Age, hunger, thirst, afflictions (such as diseases, curses, and poisons), and natural healing don't function in the Astral Plane, though they resume functioning when the traveler leaves the Astral Plane.

The Astral Plane is not Timeless in regards to magic, so you couldn't cheap (cheat?) permanence a Demiplane from there.

However Create Demiplane, Lesser states that:

You must be on the Astral or Ethereal Plane or on a plane that has access to one of those planes (such as the Material Plane) to cast this spell.

If you can find another plane that does feature Timeless magic and has access to the Astral or Ethereal planes (and you could convince your GM that this would work), you would be able to cast one of the forms of Create Demiplane there and thus have your own permanent Demiplane, although as the Timeless feature states it will still be susceptible to dispelling.
