Encounter 2: The Shadow Generator (Death King's Grotto, MMotRS)
The room starts out with 1 Shadow per Hero. At the beginning of each subsequent round, an artifact near the back of the room on an altar causes 1 more Shadow per Hero to be summoned. It contains a total of 4 additional Shadows per Hero before it is run dry. The players can discover the artifact using Assess. When they do so, they learn how to shut it off before all of the Shadows are summoned, which lasts for 24 hours.
