Treasury and Relics
Land of Empires: Immortal Guide
The treasury building in Land of Empires unlocks when you reach City Hall level 16. The purpose of the building is to allow you to obtain and upgrade Relics to further enhance your heroes and troops.
The building it self is only built and cannot be upgraded.
Relics
Relics in Land of Empires will provide your with buffs to your Heroes attributes and to your troops. They are divided into 3 sections (1 for each hero/troop type) with 3 relics in each of the sections. This gives you 9 relics to unlock and upgrade.
Relics will give boosts to 2 of either ATK, DEF or HP for each hero type, e.g. Cavalry Hero ATK and Cavalry Hero DEF. And at the same time boost the HP and/or Ferocity of The same troop type.
Upgrading Relics
Relics are Enhanced (and initially activated) with a currency called 'Rejuvenation Stone'. You can gain more of this currency by the Altar of Trial Event as well as through in game purchases.
Each relic has 5 major stages to upgrade through with each level having star levels within it.
Grey: 1 Star, 2 Stars, 3 Stars
Green: 1 Star, 2 Stars, 3 Stars
Blue: 1 Star, 2 Stars, 3 Stars, 4 Stars
Purple: 1 Star, 2 Stars, 3 Stars, 4 Stars, 5 Stars
Orange: 1 Star, 2 Stars, 3 Stars, 4 Stars, 5 Stars
You will need an increasing amount of rejuvenation stone for each upgrade.
