Sorry, but how do the DOS items have any place in a Forgotten Realms D&D game? So, not only do we need to suffer your mechanical additions, which actually reduce options in the game. But now we need to suffer thematic additions to a D&D game from DOS. If I wanted a DOS game, I would have bought a DOS game.
Hmmm.... a fantasy game that includes multiple planes of reality AND a multiverse.... yeshhhh.... how could THAT poooooooossibly work as a believable thing in a - again - FANTASY game?!
I bet I could beat ChatGPT in coming up with 20 plausible (reality tear in the Weave, etc. etc. etc.blablabla) ways of making up a believable explanation for something like this to happen. But that's not even the point.
Incidentally, are you acquainted with the terms "gag gift" or "easter eggs"? Because THAT's the point.
