Sanctuary Upgrade Requirements in Last Asylum Plague
Optimizing Construction Queues & Prerequisites
The key to efficient progress in this guide is mastering building timing and sequence, especially once you unlock the second construction queue. (if you can only buy 1 thing, this is it!) The Sanctuary upgrade requirements are one of the most important guides on this site!
To maximize time and contruction upgrades, align required prerequisite upgrades while your main Sanctuary upgrade (or other buildings) is running using the Sanctuary upgrade requirements chart below. For example, when pushing to Sanctuary 11, work on the Research Lab, Wall, and Antitoxin Workshop in parallel. That way, the moment Sanctuary 11 finishes, you can immediately start upgrading your Research Lab to level 11 without delay.
