Design a Magic System for Your Fantasy World

Magic without rules is just vibes. This designs a system from the ground up: where power comes from, what it costs, what it cannot do, and how the world around it reacts. You get something a player or reader can engage with rather than a hand-wavy plot device.

<task>
**Design** a complete magic system by answering the following:
1. Source: where does magical power come from and who has access to it?
2. Cost: what does it take from the user (time, health, resources, risk)?
3. Limits: what can magic not do, and why?
4. Visibility: what does magic look like, sound like, feel like to a bystander?
5. Social context: how does society treat magic users (feared, revered, licensed, hidden)?
6. Three worked examples: spells or magical acts that show how the system operates in practice
</task>
