Archaic Petra

Archaic Petra is an Artifact Set designed mainly for Geo characters to take advantage of, and one of its effects is to significantly enhance the damage of those who have an active Crystallize shield, an Elemental Reaction in Genshin Impact that is quite mediocre and therefore not generally recommended.

Because of this, we do not recommend this Artifact Set except for the 2-piece bonus. That is interesting because it provides Geo Damage, something that all characters of this element can benefit from.
