How do you feel about stories with multiple different power/magic systems?

I usually use the term power system since I feel like magic system is too restrictive but anyways, what’re your guys thoughts about it?

Edit: Some asked for clarification so I will use both an established work and some of my own as explanation.

One Piece - One Piece (to my knowledge) has two power systems, Haki and Devil Fruits. They’re pretty different I would say despite one being a hard counter to each other, they’re entirely two separate power systems. I don’t think the power systems in a story have to directly interact the same way Haki counters devil fruits, I just think they have to be in the same story and be two unique systems of which characters perform supernatural feats, which is what a magic system is in the first place.

A World I’m Making: Imma try and keep this short before I ramble on for too long, but one of my new stories I’m writing has several power systems which pretty much get introduced every arc or so. The reason for this or that has way too convoluted worldbuilding that’s not releasing rn:

As an example, in one of the later arcs, the mc discovers a hidden underground vault which only he could've found because dragon blood, and learns of a great ancient war between dragons and giants, to which the giants lost but the aftermath of said war led dragons to fall as well. Our mc manages to accidentally trigger some sort device with his blood and since every vault is connected, suddenly, every draconic vault has been made available to be opened by anyone, regardless if they have draconic heritage or not.

Thus triggers a draconic golden age with people finding and raising dragons from dragon eggs, cults that worship dragon gods and practice draconic magic, lost highly advanced draconic technology behind plundered and used for the user’s own benefit etcetera.

Then, later on in the story (well, A LOT LATER ON), dragons have become integrated into society and now you have dragon riding schools and mc even gets hired by the government to become a Voyager, what they call people who find open draconic vaults/ruins, and also write journals Marco Polo style on dragons and vaults (he writes a series of books called how to train your dragon lmao)

So, he decides to take a rest by visiting a foreign country and ope, it gets nuked. I won’t get into detail onto why or the details of the new power system introduced, but later on (after several arcs set in the new nuked wasteland), the radiation ends up giving people superpowers, the system is very very different from the draconic one from before. Basically a whole different system.

This is what I mean by two different power systems in a single setting. This doesn’t mean that the two systems have to be entirely disconnected and unrelated, I think they could be something like One Piece or has some lore reason for why the two systems may be linked, but when I say two power systems, I mean like two different systems with powers that have different rules.

Demon Slayer with breathing techniques and blood demon arts. They are certainly linked and you even have a character who uses both but I still consider them two different power systems.

Hope this sheds some light on what I’m asking. 👍
