Relics are a special type of building and the central element of the second post-release major update. They allow players to benefit from special abilities or bonuses but need to be forged first by assigning Smiths to a Forge.
A relic cost 100, 50 and 10 and takes 8 months to be forged with two regular smiths. Once built it needs to be placed in an area like a regular building.
It is not possible to build more than one relic per game. Only Horse clan can build a second one by the lore Ancestral Influence.
Allies cannot build the same relic. It is not possible to use another player's relic, even if you colonize a zone containing a relic that your clan could build.
While some relics are common and can be built by any clan, others can only be built by one specific clan.
A relic cannot be removed or destroyed once built. The same goes to a relic in an area that has been colonized.
In their October 2019 AMA, the developer team announced that more common relics may appear in the future.
Mjölnir : Summons a thunderstorm on a zone, damaging all units and buildings during one month.
Svalinn : +50% defense for units in this zone. Can be moved into another zone within your territory. Protects the zone against some negative effects that target it.
Gefjun's Jar : You can summon new villagers for Food depending on your population. They will arrive at your Town Hall by boat. Required happiness for your population is reduced.
Horn of Managarm : Summons up to 3 White Wolves under your control for 50 Food each, with the cost being reduced by half if you build it in a Wolf Den tile. You can summon them every 2 months. 3 is the total maximum number; if you summon 3 wolves and lose 2 of them, next time the Horn of Managarm is off cooldown you will be able to summon only 2 wolves.
Aegir : Torfin can use Provocation : All enemy units and towers target Torfin during a short period and his defense is increased by 100% for 6 seconds.
Glepnir : Allows you to place a trap in a non-enemy zone. Activate on demand to reveal spikes that damage and slow enemies for as long as they are in the zone. Lasts 30 seconds.
Yggdrasil's root : The zone where Yggdrasil's Root is built becomes “Eldritch". Every 4 months, another zone becomes eldritch. Units in Eldritch zones benefit from periodical production bonuses. Enemy units in an eldritch zone have a chance to pick a fight with their own kin for 5s.
