Once your economy is stable and you have a small military force (around 5-7 Murmillos), begin actively scouting for the relic. The relic's location is usually marked on the mini-map once discovered by your Oracle Scout. It will typically be in a contested area, guarded by enemy units. Before advancing, ensure you have researched any available military upgrades at your Barracks, such as 'Copper Weapons' or 'Copper Shields'. Group your military units with Arkantos and move cautiously towards the relic's location.
Engage enemy patrols and guard units strategically. Use Arkantos's hero bonus against Myth Units if present. Once you reach the relic, simply move Arkantos or any hero unit close to it to pick it up. Be aware that picking up the relic might trigger an enemy counter-attack or reveal new enemy positions. Be prepared to defend your hero and retreat if necessary. After securing the relic, the mission objective will update, often requiring you to return it to a specific location or defend your base from a final assault. Always keep your military units together and use formations to your advantage.
