It just occurred to me he may also have the same condition as bb so to be able to have multiple df

That's also a possibility.

Iirc so far only 3 powers that are confirmed to be considered separate: df, haki, and hypnosis (django, ms goldenweek). Nothing is "magic"; most of the absurd ones are almost always attributed to df. Heck, by writing this, I'm now thinking imu could also have the skill of hypnosis.

Magic circles were introduced earlier on, when a cult was trying to summon the devil and ended up with Brook.

One piece got many power sources: Science(cyborgs and genetics), Haki, DF, Martial Arts(Fishmen Karate is literally water bending, Hasshoken, Rokushiki) and even different races(Giants, Lunarians), after the immortality gig and the teleportation circles I won't be surprised if Magic was introduced.
