You can craft regular Ancient Relics and Special Event Gear Relics. They both fall into the five categories of Weapons, Helmets, Armors, Accessories, and Foot Armor. Special Event Gear requires special materials that do not become available until the event. Regular Ancient Relics require the regular materials: Wood, Stone, Ore, Food, and Silver. Anicent Relics only grant boosts for a set amount of time. When the relics is initial equipped the timer starts. The timer cannot be stop, it runs until it expires. Restorative research can improve how long a timer lasts. When the timer expires the Ancient Relic disappears. Any materials used to craft the relic are gone. Any gems embedded in the relic return to your Inventory in the Forge.
