Suggestion on Making a spell: Improved Shrink Item


Homebrew and House Rules


What would be a reasonable way to make a 4th level version of Shrink Item spell?

Thing Is, im playing a SpellJammer Campaign (In case you never played it before: Do so. Probably the best high adventure campaign setting ever made) and I realized that with the spell, I could very reasonably Allow for an insane level of storage of ships inside another ship.

A 1 ton ship called the flitter, could be carried by the hundred thousands using the spell. But this had me thinking of other ways to use this spell:

It could be used to shrink all the parts needed to assemble a ship, and assemble it inside a smaller area, then released and then enlarged.

But anyway back to the question at hand:

How much would the level increase be for:

A Mass version of the spell?
A Version that effects more cubic meters of stuff?
One that could be permanent without the expense of permanency?

Or is there any way to combine multiple castings (From multiple people) into a singular object?


This should go in Homebrew.

But, to answer your question, it's best to consider the difference between existing spells.

Mass version- what is the level difference between Enlarge Person and Mass Enlarge Person?
Effects more cubic meters- what is the level difference after applying the Enlarge metamagic?
Nope, making things permanent is what permanency is for.
No idea about multiple castings.


Thanks for the help but disagree on the permanency. Im certain that skill and knowledge can replace just spending lots of money on a project.


Dotting for interest.

Definitely should be in homebrew. However, advice: none of the things you're looking for (especially permanency) are appropriate for a single spell level increase. As a rule, creating a Greater or Mass version of a spell is at least an increase of two spell levels. You could go Communal, but the only way that makes sense is by dividing the amount of possible shrunken material between all the items you're shrinking.


OK. I just use this mainly as a backup forum. Giantitp is down and Im unfamiliar with the layout of these messageboards.

Would put into homebrew If I knew.


Might be able to make communal shrink item. Have the wizard on the ship to recasting. Of course that wizards is also going to be using all his 3rd level spell slots on normal shrink item. Anyone want to run the numbers on how much more cargo this would allow a ship to carry? Wonder if the increase carry is worth the wizards fee.


I wouldn't allow such a spell really, I see too much potential for world consistency, in no time at all this will be a common 'tactic' if allowed, not something I'd like in my campaigns, so to preserve that a similar spell should at least be high level.

Polymorph any object (8th level) can already do the things you want, which is fine by me at that level.


Well if there aren't that many 7th level wizards (not unlikely 7th is high for a NPC) or these wizards can make more money in other way well staying at home I see no reason why such a spell would affect world consistency.

Elves have their own Military Mages that work for them, they got them by the ears and work for them. And on huge ships like the Armadas (Check out the setting. Its worth your time. There are even a few easy to access 3e conversions that are easy as pie to convert too PF) have many Wizards working on it at a time.

5th level ones are even likely to be flunkies.

And thing is: GM powers. Im a firm believer in GM powers. In that what I say smashes what the rules say.

And I say that "Nakadoroms Improved Shrink Item" was made possible by a discovery of a rare material component (expensive/prohibitive for everybody else. Cheap for the Elven Military as they have the lone location of the component). It allows a much improved version of the spell be available as a 4th level spell.

Im the GM. And I have the bloody say in the game. Not whats written on the paper.
