A runic floor that opens only when five of its tiles are held down at once.
Twenty-five runic tiles glow faintly in the floor of an old wizard's vault, and five iron weights sit in a rack by the door. The wizard's note says the vault opens for anyone who can count like the dice. Put a weight on the wrong tile and the vault takes offence.
The tiles hum as a weight settles, and their runes brighten.
