You could have a "once per day" instantanous spell item for the command word formula which provides conveniently the very similar Cape of the Mountebank example. But you won't get once per round effects for a similar price.


Luckily "Create Food and Water" is not actually an instantanous spell, it has 24h duration.
You're right, I was probably looking at the 5E version (same graphic layout, fonts, colors on the SRD website, My fault.).

Create Water *is* instantaneous, FWIW. Then bring it to the Prestigiditation Station to get it flavored for 1 hour.

You could make a use activated item for it for only 15k. But that would not produce food every round. It would continuously produce exactly as much food as 15 humans or 5 horses need in the same timeframe.
I don't think there's anything in RAW that limits a magic item based on the duration of the spell. IT factors into the cost, and if you want to escalate the cost I think there's an argument-by-analogy, but RAW doesn't give you a real formula to do that past x4--at least I don't see a formula that scales up or down.

The balance limitation is supposed to be that you need to pretty much spend an entire dragon hoard to do it, so it's out of hte PC's reach except as a campaign capstone.
