Give a fantasy rule a visible consequence

State what the rule allows, what it costs, and what happens when characters test its limits. Show the cost in a scene before relying on it in the climax.

Try it

If a map shows only places its owner has visited, make the party obtain information another way before crossing an unknown border.
