Ritual

Rituals are a map mechanic. Rituals are mysterious sacrificial sites built by the King in the Mists. Interacting with a ritual altar after defeating the enemies in a circle marked around the altar will begin the encounter. A dark mist will surround a circle around the altar, preventing the exile from leaving, and previously killed monsters will be resurrected. Killing monsters within the circle will grant tribute. After a ritual altar is complete, tribute earned can be spent at the altar for rewards. Multiple ritual altars will appear in a given map; when they do, monsters sacrificed at previously completed altars will reappear at following altars.

Omens are an exclusive reward from ritual altars.
