What is confirmed

Replayable missions, modifiers, skill achievements, loot, builds, and bosses are confirmed. Deluxe includes access to an announced post-launch expansion, but the cited sources do not define a named post-campaign endgame mode or give the expansion a date, roadmap, or seasonal cadence.

The base structure already supports replay through new missions, modifiers, skill achievements, gear experiments, and escalating wards without naming a separate endgame activity.

What the sources do not establish

Repeatable missions are not proof of a named post-campaign mode, roadmap, seasons or expansion schedule. The Deluxe expansion promise confirms future content access but does not reveal its format, size, launch window, eligibility outside Deluxe, or relation to the campaign ending.

How to use this information
