Demigod Wiki
Crystal of Health

An image of the Crystal of Health.

The Crystal of Health (often referred to as a Health Crystal) is a structure that removes negative effects from demigods and restores their health and mana. The in-game description of the crystal:

Demigods near the holy crystal will remove negative effects[sic] and regain Health and Mana.

Every map contains a crystal in each team's base, but some maps such as Exile and Mandala have crystals that are controlled by flags.
