Sanctuary level
Sanctuary 15
Early Game · Raising the Walls
Sanctuary 9–20
To upgrade your Sanctuary from level 14 to 15, you need Research Lab 14, Training Grounds 14, Herb Garden 7 and 201 Clinic stars. It costs 6.47M Grain, 6.47M Timber and 2.29M Herbs and takes 22h 15m before any speed-ups. It raises your heroes’ level cap from 70 to 75. It also opens the Raven Workshop and the Hall of Honor.
What you need
To upgrade from Sanctuary 14 to 15.
- Research Lab 14 · my take: keep up with your Sanctuary
- Training Grounds 14 · my take: keep up with your Sanctuary
- Herb Garden 7 · my take: park for later
- 201 Clinic stars. Upgrade your Wards to earn them.
Those buildings have needs of their own. The Sanctuary build path plans every step from Sanctuary 14, on as many build queues as you have.

- 90 more levels of research you already have
It also lets 27 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 15 is part of the early game (Sanctuary 9–20). Finding your feet: learn the world and its events, settle into an alliance, and learn to work to the clock cycles.
Next up, Sanctuary 16 asks for Research Lab 15, Warrior Statue 14 and Granary 7, and takes 1d 7h 9m. Getting those ready while this upgrade runs keeps your builders busy.
