Hello! Recently I was asked by one of my friends how to make consuming an item take you to a new map. I figured it out and decided to share in case anyone else was wondering; it's kind of a complex situation.
So! First you're going to make a new state.
It should look just like this.
No features or anything.
Now, make sure your item that you want to transfer you inflicts this state.
Alright, next, make an event anywhere in the map that the player is going to transfer
from. If you make it in the map the player will transfer
to, nothing will happen.

It doesn't matter where it is, really.
Now, create a new conditional branch and set it to happen if any character uses the item.
If there is more than one character, you'll have to create multiple conditionals, each one for a different character, in case the player chooses to use the item on a character other than the main one.
Now, add the transfer. It should go just on the first @> command under the conditional.
Make sure the trigger is on Parallel Process, and there is nothing happening on the second branch.
If you want something to happen before the transfer, put it on the first branch, before the transfer command.
I hope this helps any beginners!

It was a pain in the ass to figure out, so I thought I'd upload it to help anyone else.
If you have any questions, feel free to ask~
