Perpetual Heart is an Elemental Stone material of Character Ascension Material in Genshin Impact.
Description: The core that powers the autonomous movements of the Perpetual Mechanical Array. Some theorize that the symbols on these cores have knowledge and logic inscribed upon them in a language that eyes cannot perceive. Some go a step further and believe that these unique Ruin machines autonomously decided to forsake a biomimetic form to pursue strength of function on account of their especially large cores and complex inscriptinos.
