Hard vs Soft Magic Systems
Magic that is rule-bound generates plot; magic that is mysterious generates wonder.
Principle
The reader can only be surprised by magic in proportion to the rules they understand.
Takeaways
- Hard systems can solve problems on the page.
- Soft systems should not solve problems they have not earned.
- Most stories blend the two; the failure is when the reader cannot tell which they are in.
Overview
A hard magic system has explicit rules, costs, and limits known to the reader; a soft system is mysterious and resists explanation. Sanderson's First Law: the reliability of magic to solve problems is proportional to the reader's understanding of it.
Examples
- A hard system: every spell costs a measurable physical price.
- A soft system: a wizard whose powers are ancient and unspoken.
- A blended system: hard rules at the surface, soft mythology beneath.
