Freeze three lanterns within ten seconds, then use the Ice Staff to lower the three marked rocks in the Nexus. Select the three glyphs you actually see. Names below are visual memory aids.
Choose the three symbols actually visible on your rocks (0/3).
Reference numbers identify rocks; they are not an order to shoot. Only the three marked rocks in your game determine your selection.
Tombs / bull mural: I through VIII. Catacombs / archer mural: I through X. Shoot in ascending order. A stroke before V or X subtracts one: IV = 4; IX = 9.
