I'm looking for any novel or fan fiction where the MC has a magic or power system that's unique and different from the world he/she is in. I've read a lot of fanfic like this such where a D&D or Harry Potter magic system or Fate series characters in another world. Or something like Dao of Magic. I would especially like it if the MC teaches/grants someone else his system. I like bringing weapons and skills from another world to another as well.
Solo Leveling? The manhwa, I mean. Haven't read the novel, but the manhwa is the hottest shit out there right now. (also realized that I have it as my avi even)
The Death Mage who doesn’t want a fourth time is a good one. If you haven’t read yet, it’s about a half vampire child (Dhampir) that’s actually a reincarnated person twice over that checks off both things your looking for. He’s so overpowered that he’s slain several gods and rules a nation before he hits his teen years.
If u want a unique magic system then The Beginning After The End is good with a new way of magic but the MCs own system is not much different than the rest , same is with Supreme Magus and Abuse of Magic ( he does teach his system to others ) but all them have a more comprehensive system of magic than a completely different system than the rest , ur best bet would be fanfics with crossovers of a person from one world using other worlds system there. Again if it's only uniqueness u want then the options provided by me and others above me r a good start
