Sanctuary level
Sanctuary 24
Mid Game · The Long Siege
Sanctuary 21–29
To upgrade your Sanctuary from level 23 to 24, you need Research Lab 23, Walls 23, Lumber Depot 10 and 282 Clinic stars. It costs 171M Grain, 171M Timber and 56.3M Herbs and takes 15d 19h 21m before any speed-ups. It raises your heroes’ level cap from 115 to 120.
What you need
To upgrade from Sanctuary 23 to 24.
- Research Lab 23 · my take: keep up with your Sanctuary
- Walls 23 · my take: keep up with your Sanctuary
- Lumber Depot 10 · my take: park for later
- 282 Clinic stars. Upgrade your Wards to earn them.
Those buildings have needs of their own. The Sanctuary build path plans every step from Sanctuary 23, on as many build queues as you have.

- Elite Troop: Quick Bandage I, Infirmary Expansion I and Survival Skills
- Offensive Tactics: Barracks Expansion and Lightning March I

- 74 more levels of research you already have
It also lets 30 of the buildings you already have go higher. From Sanctuary 7 on, a building can only be as high as your Sanctuary, which is why the Sanctuary sets the pace for everything.
Where it fits
Sanctuary 24 is part of the mid game (Sanctuary 21–29). Level up and contribute to your alliance. The hard part: upgrades stretch from days to weeks.
Next up, Sanctuary 25 asks for Research Lab 24, Training Grounds 24 and Herb Storage 10, and takes 22d 3h 5m. Getting those ready while this upgrade runs keeps your builders busy.
