No. What he's saying is easy.
Start Up The Tool
Scan for Magic that YOU ALREADY HAVE IN GAME!
Find Magic - Swap it out for something in the pre-set item roster that you want.
That's what he's saying
What I am saying
If you have no magic IN GAME and you go to scan for magic in your inventory, none will show up since you well...have none.
If you go to put magic in (under the current bug issue) you'll have it but you can't attune it.
In the video I showed this already. You can't make something from nothing. Meaning if you have no magic to begin with, then Casey's trick doesn't work for you.
