Free magic system generator Roll a magic system, down to what it costs the caster.

Each roll names a magic system and spells out where its power comes from, who can use it, what it costs, and what it can’t do, along with the one use the law forbids. It’s free and needs no account, and there’s no AI in it, since every line is picked from tables we wrote. Use the result in your campaign, or open it in LoreWeaver as a world you can play.

The short answer

How do I create a magic system for my world?

Start with where the power comes from and what it costs, then decide who can use it and what it can’t do, because a real price and a firm limit are what make magic feel believable. Add how ordinary people treat it and one use that’s against the law, and you already have the start of a plot. LoreWeaver’s free magic system generator rolls all of these at once from tables we wrote, with no AI and no account. Reroll any line that doesn’t fit and keep the rest.

Three rolls

Three magic systems rolled for this page.

These came from the tables behind the generator at the top of the page, so they show the range you can expect. Some combinations line up neatly and some pull against each other, and the second kind often gives you the better story.

Using a result

Put the magic to work at the table or in a story.

  1. 01

    Read it

    Start with the price

    Look at the cost and the limit before anything else. Ask who pays that price most often, who can’t afford it, and what someone would risk to get around the limit. The answers usually point to your first scene.

  2. 02

    Campaign

    Bring it to your table

    Give the players a practitioner they can hire, or make one of them a person who can use it. The sign tells you what other characters notice when it happens, and the forbidden use gives the law or a rival a reason to come knocking.

  3. 03

    Novel

    Fold it into a draft

    Copy the text into your notes, keep the lines that suit the book you already have, and rewrite the others in your own words. Whatever you keep is yours to use.

  4. 04

    Play

    Play a world built on it

    Press “Build this world” and LoreWeaver’s world builder opens with the result already typed in, after a free sign-up if you don’t have an account. It turns that one idea into a playable world, where an AI storyteller runs the story and you act in it as someone who can use the magic.

Questions

Questions, answered.

01Is this magic system generator free, and does it use AI?

Yes, it’s free and needs no account, and it doesn’t use AI. Every result is put together from tables we wrote, picked at random, which is also why the same link always brings back the same magic system.

02Can I use these magic systems in my campaign, book or game?

Yes. Whatever you roll is yours to use and change, whether that’s for a tabletop campaign, a novel, a game you’re making, or a world you play on LoreWeaver.

03How do I share or save a magic system?

Every result has its own link, because the codes for each line are in the page address. Copy the link to share that exact result or to come back to it later, or copy the text if you’d rather paste it into your notes.

04Can I reroll just one part of a result?

Yes. Each line rolls on its own, so you can reroll the cost or the forbidden use and keep everything else as it is. The new version gets its own link too.

05How many different magic systems can it make?

It can roll 100,080,648,360,000,000 different ones. Each line comes from its own table, and the name joins two of them, so the chance of rolling the same magic system twice is close to nothing.

06What makes a magic system feel real?

Costs and limits. Magic that can do anything for free solves every problem before it becomes a story, while a price someone feels and a rule that can’t be bent force hard choices. That’s why every result here comes with both, along with how ordinary people react to it, which shows how the world has changed around the magic.

07Can I play a world with this magic on LoreWeaver?

Yes. Press “Build this world” on any result and LoreWeaver’s world builder opens with it already typed in. If you don’t have an account yet, you make a free one first. It turns the idea into a world where an AI storyteller runs the story and you act in it. A lore card holds the magic’s rules so the storyteller sticks to them, and story memory writes down what happens every few replies, so a price you paid early on still matters later.
