What is a magic system?

A magic system is the set of rules behind magic in a fictional world: where power comes from, what it can do, what it costs, what limits it, and who can use it. Strong systems make every spell a choice, because every spell takes something away.

Ley Lines

Place · High fantasy · Hard magic

Power flows along mapped lines between ancient standing stones.

Cost: Drawing power drains crops and wells along the line for a season.

Limit: Every line's strength is measured and mapped, and the maps are worth more than gold.

Conflict: A new stone appears overnight and bends a line through the capital.

Writers usually place a system between hard magic, with rules the reader can learn, and soft magic, which stays mysterious. This generator has 16 of each and 92,160 blueprints for designing your own.

Hard magic vs soft magic

Hard magic: Clear rules the reader can learn and predict. Soft magic: Mysterious and unpredictable, even to its users.

Aspect	Hard magic	Soft magic
Rules	Explained to the reader	Hidden or never fully explained
Can it solve the plot?	Yes, because readers know what it can do	Rarely. It works best when it creates problems
Reader feeling	Cleverness and fair-play payoff	Wonder, dread, and mystery
Famous example	Allomancy in Mistborn	Gandalf's wizardry in The Lord of the Rings
Example in this tool	Ley Lines: Every line's strength is measured and mapped, and the maps are worth more than gold.	Whispered Curses: Nobody controls what form the curse takes.

Sanderson's Laws of Magic

Fantasy author Brandon Sanderson published three guidelines for writing magic in essays on his website.

Law	Wording	What it means for your system
First Law (2007)	“An author's ability to solve conflict with magic is directly proportional to how well the reader understands said magic.”	Hard magic can solve problems. Soft magic should create them.
Second Law (2012)	“Limitations > Powers.”	What magic cannot do, and what it costs, is more interesting than what it can do.
Third Law (2013)	“Expand what you have before you add something new.”	Explore a few powers deeply instead of adding many shallow ones.

Magic system examples from famous books and shows

8 well-known systems, from the strict rules of Allomancy to the mystery of the Force.

System	Work	Creator	Year	Type	How it works
Allomancy	Mistborn: The Final Empire	Brandon Sanderson	2006	Hard	Users swallow and burn metals. Each metal grants one power, and the fuel runs out.
Sympathy	The Name of the Wind	Patrick Rothfuss	2007	Hard	Links two objects so energy passes between them. The energy must come from a real source, such as heat.
Alchemy	Fullmetal Alchemist	Hiromu Arakawa	2001	Hard	Transmutation follows equivalent exchange: to gain something, something of equal value must be lost.
Vancian magic	The Dying Earth	Jack Vance	1950	Hard	Wizards memorize spells, which vanish from memory once cast. Dungeons & Dragons (1974) borrowed it.
Bending	Avatar: The Last Airbender	Michael Dante DiMartino and Bryan Konietzko	2005	Hard	Benders are born able to control one element, drawn from martial arts styles.
True names	A Wizard of Earthsea	Ursula K. Le Guin	1968	Soft	Knowing a thing's true name gives power over it, and every act of magic must respect the world's balance.
The Force	Star Wars	George Lucas	1977	Soft	An energy field created by all living things, sensed and used by Jedi and Sith.
Wizardry	The Lord of the Rings	J. R. R. Tolkien	1954–1955	Soft	Gandalf's powers are never fully explained, which keeps the world vast and mysterious.

How to create a magic system

Seven steps from power source to the conflict that tests it.

1
Choose where power comes from
Pick a source: ritual, bloodline, place, words, bargain, relic, body, divine. The source decides who can reach magic and what feels natural in your world.
2
Decide hard or soft
If magic will solve plot problems, make it hard and explain the rules. If it should stay mysterious, make it soft and keep it from saving the day.
3
Set a cost
Make every use cost something the user values: memory, years, body heat, or relationships. The cost turns casting into a choice.
4
Add limits
Write down what magic cannot do: range, timing, materials, or targets. Limits create problems that characters must solve without magic.
5
Decide who has access
Born with it, trained, chosen, or paid for. Access shapes class, politics, and resentment.
6
Show it in daily life
Ask how magic changes jobs, laws, religion, and war. A system feels real when ordinary people have opinions about it.
7
Break it with a conflict
Test the rules with a problem that pushes on them: a loophole, a shortage, or someone paying the cost for another.

Magic system terms

12 words writers and game designers use when talking about magic.

Magic system: The rules, costs, and limits that govern how magic works in a fictional world.
Hard magic: Magic with clear, consistent rules the reader understands well enough to predict.
Soft magic: Magic that stays mysterious, with rules hidden from the reader and often from the characters.
Sanderson's Laws: Three guidelines for writing magic by fantasy author Brandon Sanderson, published as essays in 2007, 2012, and 2013.
Cost: What a user gives up to cast: energy, memory, years, or something rarer. Costs make every use a choice.
Limitation: What magic cannot do. Sanderson's Second Law holds that limitations are more interesting than powers.
Equivalent exchange: The rule in Fullmetal Alchemist that gaining something requires losing something of equal value.
Vancian magic: Spells memorized and forgotten once cast, from Jack Vance's The Dying Earth (1950) and adopted by Dungeons & Dragons in 1974.
Sympathetic magic: Magic based on likeness or contact, so acting on one object affects a linked one. James George Frazer described it in The Golden Bough (1890).
Ley line: An alignment between ancient sites. Alfred Watkins coined the term in 1921, and fantasy often treats ley lines as channels of power.
True name: A hidden name that grants power over its owner, central to Ursula K. Le Guin's A Wizard of Earthsea (1968).
Deus ex machina: Latin for "god from the machine": a sudden, unearned solution. Clear magic rules prevent it.

Frequently asked questions

The 32 systems, hard and soft magic, Sanderson's Laws, and building your own.

What is a magic system generator?+

A magic system generator gives you the rules for how magic works in a story or game. This one draws from 32 complete systems across 8 power sources and 4 genres, and builds 92,160 blueprints from costs, limits, access rules, and worldbuilding questions.

What is a magic system?+

A magic system is the set of rules behind magic in a fictional world: where power comes from, what it can do, what it costs, what limits it, and who can use it.

What is the difference between hard and soft magic?+

Hard magic has clear rules that the reader understands, so it can solve problems fairly. Soft magic stays mysterious, so it creates wonder and danger but should not resolve the plot. Allomancy in Mistborn is hard magic; Gandalf's wizardry in The Lord of the Rings is soft.

What are Sanderson's Laws of Magic?+

Three guidelines by Brandon Sanderson. First Law (2007): "An author's ability to solve conflict with magic is directly proportional to how well the reader understands said magic." Second Law (2012): "Limitations > Powers." Third Law (2013): "Expand what you have before you add something new."

How many magic systems does this generator have?+

32: one for each pairing of 8 sources (ritual, bloodline, place, words, bargain, relic, body, divine) and 4 genres (high fantasy, urban fantasy, dark fantasy, science fantasy). 16 are hard magic and 16 are soft.

What does each magic system include?+

A name, a one-line summary, what it does, its cost, its limit, who can use it, how society treats it, and a story conflict that tests the rules.

What is the Build your own mode?+

It gives you the bones of a new system: a power source, one of 12 costs, one of 12 limits, one of 8 access rules, and one of 10 worldbuilding questions. That makes 92,160 combinations.

Why do some filter combinations show no results?+

Each source and genre pairing has one system, and it is either hard or soft. If you pick a source, a genre, and the other hardness, the tool tells you which system fits and what kind of magic it is. Leave hardness on Either to see it.

How do I give magic a cost?+

Make the cost something the character values and cannot easily replace: memories, years of life, body heat, relationships, or luck. Then put the character in a scene where paying it hurts.

Which famous magic systems are hard and which are soft?+

Hard: Allomancy, Sympathy, Alchemy, Vancian magic, Bending. Soft: true names in A Wizard of Earthsea, the Force in Star Wars, and wizardry in The Lord of the Rings. All are listed in the table on this page.

Can I use these magic systems in D&D or other tabletop games?+

Yes. Use a system as a homebrew subclass theme, a regional magic tradition, or the secret behind a campaign villain. The cost and limit lines translate directly into house rules.

Can I use these magic systems in my book?+

Yes. Use them as written or adapt them for stories, games, and worldbuilding projects.

Is anything uploaded?+

No. Systems and blueprints are picked in your browser.

How to create a magic system

Seven steps from power source to the conflict that tests it.

1
Choose where power comes from
Pick a source: ritual, bloodline, place, words, bargain, relic, body, divine. The source decides who can reach magic and what feels natural in your world.
2
Decide hard or soft
If magic will solve plot problems, make it hard and explain the rules. If it should stay mysterious, make it soft and keep it from saving the day.
3
Set a cost
Make every use cost something the user values: memory, years, body heat, or relationships. The cost turns casting into a choice.
4
Add limits
Write down what magic cannot do: range, timing, materials, or targets. Limits create problems that characters must solve without magic.
5
Decide who has access
Born with it, trained, chosen, or paid for. Access shapes class, politics, and resentment.
6
Show it in daily life
Ask how magic changes jobs, laws, religion, and war. A system feels real when ordinary people have opinions about it.
7
Break it with a conflict
Test the rules with a problem that pushes on them: a loophole, a shortage, or someone paying the cost for another.

Magic system terms

12 words writers and game designers use when talking about magic.

Magic system: The rules, costs, and limits that govern how magic works in a fictional world.
Hard magic: Magic with clear, consistent rules the reader understands well enough to predict.
Soft magic: Magic that stays mysterious, with rules hidden from the reader and often from the characters.
Sanderson's Laws: Three guidelines for writing magic by fantasy author Brandon Sanderson, published as essays in 2007, 2012, and 2013.
Cost: What a user gives up to cast: energy, memory, years, or something rarer. Costs make every use a choice.
Limitation: What magic cannot do. Sanderson's Second Law holds that limitations are more interesting than powers.
Equivalent exchange: The rule in Fullmetal Alchemist that gaining something requires losing something of equal value.
Vancian magic: Spells memorized and forgotten once cast, from Jack Vance's The Dying Earth (1950) and adopted by Dungeons & Dragons in 1974.
Sympathetic magic: Magic based on likeness or contact, so acting on one object affects a linked one. James George Frazer described it in The Golden Bough (1890).
Ley line: An alignment between ancient sites. Alfred Watkins coined the term in 1921, and fantasy often treats ley lines as channels of power.
True name: A hidden name that grants power over its owner, central to Ursula K. Le Guin's A Wizard of Earthsea (1968).
Deus ex machina: Latin for "god from the machine": a sudden, unearned solution. Clear magic rules prevent it.

Frequently asked questions

The 32 systems, hard and soft magic, Sanderson's Laws, and building your own.

What is a magic system generator?+

What is a magic system?+

A magic system is the set of rules behind magic in a fictional world: where power comes from, what it can do, what it costs, what limits it, and who can use it.

What is the difference between hard and soft magic?+

What are Sanderson's Laws of Magic?+

How many magic systems does this generator have?+

What does each magic system include?+

A name, a one-line summary, what it does, its cost, its limit, who can use it, how society treats it, and a story conflict that tests the rules.

What is the Build your own mode?+

It gives you the bones of a new system: a power source, one of 12 costs, one of 12 limits, one of 8 access rules, and one of 10 worldbuilding questions. That makes 92,160 combinations.

Why do some filter combinations show no results?+

How do I give magic a cost?+

Make the cost something the character values and cannot easily replace: memories, years of life, body heat, relationships, or luck. Then put the character in a scene where paying it hurts.

Which famous magic systems are hard and which are soft?+

Can I use these magic systems in D&D or other tabletop games?+

Yes. Use a system as a homebrew subclass theme, a regional magic tradition, or the secret behind a campaign villain. The cost and limit lines translate directly into house rules.

Can I use these magic systems in my book?+

Yes. Use them as written or adapt them for stories, games, and worldbuilding projects.

Is anything uploaded?+

No. Systems and blueprints are picked in your browser.
