LAST ASYLUM: PLAGUE · EVIDENCE-BOUNDED CHECKER
Sanctuary milestones and prerequisites
Use this as a quick checkpoint reference for the levels explicitly listed by the publisher-site guide.
Evidence boundary: Publisher-site guide snapshot. The page states that its progression table is based on wiki data, so Haven exposes only the listed level prerequisites and unlocks here; resource costs, timers, rush advice and optimisation claims are deliberately excluded until separately corroborated.
Check account-state blockers
Select a sourced Sanctuary milestone, then enter your current levels for only the buildings explicitly listed as prerequisites. Blank values stay unknown rather than being guessed.
Only explicitly sourced building prerequisites are checked. Resources, timers, stars, quests and unrecorded gates are outside this result.
