World / Adventure mode

Doom

Complete Rift-Star Expanse

Doom is the last progression mode and requires completion of Chapter 20.

Fear, stage advancement, and reset

Heroes who participate in a completed Doom site gain Fear and cannot be assigned to another Doom site in the same stage.
Advancing to the next stage or resetting the current stage clears Fear from the participating heroes.
Sites are sequential. A stage's team slots can be used at the same time, but each site still consumes its listed entry cost. Clearing every site completes the current stage: Dread and Suspicion then advance to the next stage, while clearing Frenzy completes Doom.
Completing a stage raises the equipment corruption cap to the value shown for that stage and permanently adds its hero level-cap bonus.

Boss and restriction pools

Dread and Suspicion use a shuffled set of unique chapter themes from Chapters 1–10. Each site's Boss comes from its selected chapter theme.

Chapter theme pool

Frenzy independently shuffles the three dedicated Bosses and the three area restrictions. No fixed Boss-to-restriction pairing exists. Each dedicated Boss also selects a theme from its available chapter pool.
