Access the Divine Era: This is generally unlocked during the campaign, and you can access it through the world map.
Travel to Heoborea: This is the main town in the snowy region of the Divine Era.
Head West: From Heoborea, travel west towards the snowy mountains.
Reach Champion’s Gate: You will eventually reach the Champion’s Gate, which is marked on the map as a small castle icon.
Remember, you’ll need an Arena Key to activate the Monolith and begin your challenge.
