Astral Projection and a second life

[Oyuri]

So the wizard in my game wants to give a "second life" to everyone before fighting a boss by using astral projection

what he says is that he travels to the material plane without going back to his body and creates a new one, so when he dies he just goes back to his original body.

on the astral projection spell it says when you travel to another plane you form a new physical body, but if you travel to the material plane again, does it create another body for you or you just return to your original body and the spell ends?.

It creates a new body, the spell only ends when dismissed or the person is killed.

A cute theory but highly impractical. As it's prime base projecting to Astral, then find a portal back to the prime or attempt to project back to the prime which takes you to >some< location (planar travel is always notoriously inaccurate)... silver cord trailing...

while many GMs assume the astral copies be magical copies via Astral projection (The spell projects an astral copy of you and all you wear or carry onto the Astral Plane.), it could be mundane replicas particularly if you go prime as the new copies are formed from matter from the plane you are going to. Who knows... best to experiment and find out before you try something crazy. A Dispel magic or Dismissal might be problematic for magically projected creatures.

Check out the Astral encounter chart... sharknado cool.

It would make more sense to be Astral and project onto the Prime (if possible). Still that's a lot of spell power that Magic Jar could simulate easier or Clone being the classic 'go to' spell for this effect.
I'd suggest Getaway, Contingency with something, some talismans and aegis of recovery, false life, ablative barrier, etc.

I always read it as not being able to 'project' onto your own plane:

By freeing your spirit from your physical body, this spell allows you to project an astral body onto another plane altogether. You can bring the astral forms of other willing creatures with you, provided that these subjects are linked in a circle with you at the time of the casting. These fellow travelers are dependent upon you and must accompany you at all times. If something happens to you during the journey, your companions are stranded wherever you left them.

You project your astral self onto the Astral Plane, leaving your physical body behind on the Material Plane in a state of suspended animation. The spell projects an astral copy of you and all you wear or carry onto the Astral Plane. Since the Astral Plane touches upon other planes, you can travel astrally to any of these other planes as you will. To enter one, you leave the Astral Plane, forming a new physical body (and equipment) on the plane of existence you have chosen to enter.

While you are on the Astral Plane, your astral body is connected at all times to your physical body by an incorporeal silver cord. If the cord is broken, you are killed, astrally and physically. Luckily, very few things can destroy a silver cord. When a second body is formed on a different plane, the silver cord remains invisibly attached to the new body. If the second body or the astral form is slain, the cord simply returns to your body where it rests on the Material Plane, thereby reviving it from its state of suspended animation. This is a traumatic affair, however, and you gain two permanent negative levels if your second body or astral form is slain. Although astral projections are able to function on the Astral Plane, their actions affect only creatures existing on the Astral Plane; a physical body must be materialized on other planes.

You and your companions may travel through the Astral Plane indefinitely. Your bodies simply wait behind in a state of suspended animation until you choose to return your spirits to them. The spell lasts until you desire to end it, or until it is terminated by some outside means, such as dispel magic cast upon either the physical body or the astral form, the breaking of the silver cord, or the destruction of your body back on the Material Plane (which kills you).

When this spell ends, your astral body and all of its gear, vanishes.

Basically, you can only project to 'other' planes and not your own.
