Cult Device

The Cult Device is a special location that the player can find and, if successful, destroy to gain the choice of reducing Chaos, gaining a Life, or destroying a Scourge. The player will attempt a roll for one of the core stats. An unsuccessful Slot Outcome can result in player damage, party damage, or additional Chaos. Hovering over the Cult Device will show you the icon of which stat is going to be challenged.
