There are two types of artefacts - the standard ones and the ancient ones. The standard ones can be converted into ancient in the same way as perfecting artefacts.
Artefacts do not have effect if:
1. a Hero is stunned;
2. a Hero is in the Sanctuary;
3. a Hero is not in the domain (this is as per the Artefacts that affect domains), with the exception for Science bonus from Artefacts.
Artefacts affect buildings and special units only in the domain, where the Hero with those artefacts is.
Artefacts can be obtained from:
Artefacts appear in Ruin at the moment of Robbery against Ruin.
Chance of Artefact appearing in a Ruin depends on level of the Ruin.
No more than 1 Artefact can appear in 1 Ruin.
If several players attack same Ruin, only one random Hero will get the Artefact.
Player can steal Artefact from Ruin only if a Hero of any level participates in the Robbery mission.
Artefacts can be bought from the Trader.
Artefacts can be received as reward for the Tournament.
Artefacts can be received as reward for some quests.
Artefacts are collected in Sets.
Same Artefact can not be included into several Sets. Complete Set of Artefacts on one Hero has extra effects.
