Pokemon League Entrance
You exit Victory Road into a grand stone plaza. The League building is the giant fortress ahead. Inside: a Pokémon Center on the left (heal up — last chance), a Mart on the right (last stock), and a save point right before the Elite Four chambers.
Pokémon Center nurse: Full heal. Free, infinite use. Heal before talking to the secretary.
Mart counter: Sells max-tier items. Last chance to buy Full Restores and Max Revives.
Secretary at the central door: Asks if you're ready. Saying yes saves your game and starts the Elite Four gauntlet.
