Looking for an Item to Act as an Extradimensional Living Space


Pathfinder First Edition General Discussion


I'm wondering if anywhere in Pathfinder is a magic item that duplicates an effect similar to the old 3.5 Mordenkainen's Magnificent Mansion (or even a much much smaller version of this spell), basically creating an extradimensional and persistent living area accessible when necessary.

If not, is there any way to calculate the cost of such an item?


Mage's magnificent mansion still exists, and as such you could have a staff with it. There's also the option of a wand of tiny hut. Those are just off the top of my head as the simplest ways to do it without getting into wondrous items or actually, you know, looking it up myself.


You want an Instant Fortress. Page 520.


Sadly the Fortress is not extradimensional. The only extradimensional solution that comes to mind is the Rod of Security.

Or a custom item of rope trick.


Portable hole as long as no one closes it while you're in there. Find a way to survive without breathing and you're set.

Design a mask that attaches to a bottle of air or that Ioun stone will do the trick.

I want to make a breathing apparatus now with a bottle of air and never fall prey to inhaling poisons or disease again. Go scuba diving, live in space.


Spoiler:
In one of The Legacy of Fire APs there's a secondary adventure that not only has what your looking for but a backstory on Extradimensional spaces and how they were all the rage in Nex's day.

I believe most are like Genie lamps. But then there is Kakashon, which is a major plot element in that AP

This might help. It's older but cooler than the regular options.


Lotta cool options. Most of these options aren't persistent though, correct? As in, I can't set up a nice laboratory and have it still exist upon reopening the space.

That's an interesting idea, Zagnabbit. You wouldn't happen to have the stats on such a beast, would ye?


permanent demi plane?

it sounds like you want to be able to kind of carry it around with you though right?

A custom magical item with Mage's magnificent mansion is possible but expensive

For example the following item

Gateway Chalk
Aura strong conjuration; CL 13th
Slot none; Price 72,800 gp; Weight 0.1 lb.

This white piece of chalk is carved with a series of tiny arcane runes. If the bearer draws a gateway on any flat surface whilst uttering the command word (the gateway cannot exceed 4ft wide by 8ft high), then a portal comes into being leading to a Magnificent Mansion. The chalk can be used once a day, and the mansion lasts no more than 26 hours. When the bearer of the chalk exits the property, the command word can be uttered again to end the spell effect early. Any beings reminaing inside the Mansion are ejected and appear by the location of the gateway.


Well, if you are a mythic archmage, there's the Sanctum path ability.

Sanctum (Su) (Mythic Adventures pg. 19 (Amazon)): You gain access to your own personal extradimensional sanctum. By concentrating for 1 minute without interruption, you conjure the door to your own personal sanctum, similar to mage’s magnificent mansion, but with the following differences. The sanctum takes up a space equal to six 20-foot cubes per tier, shapeable when you first create it as if it were a spell whose area or effect is shapeable. The sanctum is permanent and persistent, so you can store objects within the sanctum and retrieve them on future visits. The sanctum includes one unseen servant per tier. When you conjure the sanctum’s door, you decide which creatures can see and use it (to all other creatures it’s invisible and impermeable). The door remains until you dismiss it—a standard action with unlimited range as long as you are on the same plane as the door. If you dismiss the door while you are outside the sanctum, all creatures other than your familiar are immediately shunted outside. Conjuring the door automatically dismisses any other active door. As a full-round action, your familiar can enter or leave the sanctum from any square adjacent to you, without using the conjured door.

Of course, you probably aren't mythic, might not be an archmage, and may not want to spend a path ability on it.

Something to that effect, yes.

Alas, so I see. Is there possibly a cheaper alternative?

None of the three, unfortunately, although frankly that seems like an awesome option. Not playing mythic, though.

No stats no.

It's basically a minor artifact that is a permanent, mobile gateway to a small, personal Demi-Plane.
Pathfinder #24 "TheFinal Wish", secondary article "Decanter of Black Death"

The above article does stat that the creator made about 300 of them though, so they aren't exactly a unique or campaign breaking item.

Any permanent, inhabitable, extradimensional space that is large enough to contain several people is going to be prohibitively expensive. The ability to use it as a treasure cache is just too much in game terms (since you never need to worry about weight or storage again, plus if it's mobile you can always have every piece of mundane equipment you could ever need). A "familiar pocket" X100 maybe?
I have a home-brewed item that does just that plus some other things, it's a Staff and it's insanely expensive even with my half-assed pricing making it barely affordable for a big level player and it only provides a space that is about 20,000 cubic feet. (like a 3 bedroom house as an example).

Talk to your DM about this, if he doesn't mind a mobile spell lab it's not an unlikely get item. While it's gold cost would be staggering it can be built in such a way as to be non-game changing, beyond saving the party from nighttime random encounter tables.

Scarab Sages

You can halve the price by making it an amulet, ring or similar as part of the cost is the fact the sample item is slotless.


In PF module "The Harrowing" there is a minor artifact called Harrow Deck which 1/day casts Gate to a specific demiplane. If you are a player just tell your GM that you want to play this.


Its not official, rather 3PP, but I created a map of an extra-dimensional object called the Amulet of Cerene, that was published as a map/magic item for Assassin's Amulet by Roleplayingtips.com - its a little pricey at $19.99 for a 300 page PDF, though.

Here's the map of the item - basically it is worn by divine assassins as a hideout and a means to hunt their prey. Its an extra dimensional space that exists within the magic item itself.

The Fortress only compacts when it's empty.


Instant Fortress is the closest item I have found to the requirements.

Creating a custom item is the best path to meet all of the requirements.
