Clue - 开演

What it controls

A clue is evidence: a visible detail, an unusual object, a reaction, or an inconsistency. It tells the player what they found without immediately explaining the answer. The example clue is Salt Mark on the Envelope. The player sees salt and water lines; the meaning is confirmed later as intelligence.

Clue versus intelligence

The clue is salt marks on one side of the envelope. The intelligence is the sender has not left the harbor. Let the player find evidence first, then confirm its meaning through an action, record, or character. Do not write “when the player is clever.” Name an action and an observable result.

Check it

Before discovery, the clue should not appear in the clue menu. After the action, it should be readable there and should lead to a later fact without already containing the whole conclusion.
