The Sanctuary is the main building in Last Asylum Plague. Upgrading it helps you progress in the game and unlock new features, including upgrades for other buildings. It also increases your Might, Hero Level Cap, Hero HP, Hero ATK, and Hero DEF.
To upgrade the Sanctuary, you first need to upgrade some required buildings and also gather stars and resources. The Lab is always required after Sanctuary level 10, while the other requirements can rotate between different buildings.
Upgrade Requirements
The table below shows the base time and resources required to upgrade the Sanctuary. The actual time and cost you see in the game may be slightly lower because they depend on several factors, such as your Builder’s Hut level, alliance research, help from alliance members, survivors, and the level 6 Noble Fortress.
