“A magic system without rules is just wish fulfillment. A magic system WITH rules is storytelling. The rules are what make the magic feel real enough to believe.”

— L.A. Walton, The Book Maven

If your magic system can do anything, it can’t create tension. And without tension, there’s no story. That’s the paradox of fantasy writing: the more powerful your magic, the weaker your narrative—unless you give it rules, limits, and costs that make every magical act a meaningful choice.

Hard Magic vs. Soft Magic

Hard MagicSoft MagicHybrid
Clear, defined rules the reader understands.Mysterious, vague, operates by unspoken logic.Some rules are clear; others are shrouded in mystery.
Solves problems directly.Creates wonder and atmosphere.Solves some problems; deepens others.
Example: Brandon Sanderson’s Allomancy.Example: Tolkien’s Gandalf.Example: Harry Potter (some rules, some mystery).
Risk: feels mechanical.Risk: feels like deus ex machina.Risk: inconsistency if not carefully managed.

The Magic System Checklist

  1. What CAN it do? Define the scope clearly, even if you don’t reveal all of it to the reader.
  2. What CAN’T it do? Limitations create tension. If magic can’t heal, death matters. If it can’t time-travel, choices are permanent.
  3. What does it COST? Every act of magic should have a price: energy, health, sanity, morality, or something else.
  4. Who can use it and why? Is it genetic? Learned? Granted? The access rules shape your world’s power dynamics.
  5. How does it affect society? Magic changes economies, politics, warfare, and daily life. Think through the implications.

Your Move, Creative

Write a one-page ‘magic bible’ for your fantasy project: what it does, what it costs, who can access it, and what it absolutely cannot do. Pin it above your desk. Consistency is the difference between a magic system readers trust and one that makes them throw your book across the room.

Stop letting your stories stay stuck.
