dry pivot
A passive item that when used creates a portal where youre standing,teleporting you, the other side of the portal is a spot that is placed in the editor. Defaults to the entrance if not placed. Portal remains linked until used again, overwriting the old portal link.
Would allow infinite and quick returns to a "main room," while also giving a teleport back to where you were.

The same thing could be recreated with countless portals placed by hand, yes

reminds me of Farore's Wind from OoT. idk if you could get away with it being a passive item, but a tool that allows players to create their own (limited) portal would be nifty.
and barring a literal Portal Gun, you could have a version of the item that has you lob a portal (like a regular thrown object) and it opens wherever it lands.

I think the intent is a "return to start" type item, like the magic mirror in aLttP
where the "start" can be configured in the editor to control what location the item sends you
with the additional effect of being able to go back, like the return to dark world "sparkle" in aLttP (except it changes your position)
It could be used in some interesting puzzles I feel
