The Relics give properties and advantages to boost the combat abilities of your Heroes and Units.
Relics are divided into three types (Archers, Cavalry, and Infantry), and each type has three Relics.
Activating and upgrading each Relic requires a specific amount of items, such as Rejuvination Stone and Elixir of Enlightenment.
For each type, when the total Relics reach a certain star level, you will unlock extra attributes.
You can view the Relics by tapping Treasury, then selecting "Relics ".
