Castle Upgrades
Resources, required buildings and base build time for every castle level from C1 to C40, plus what to skip after C30.
How much your next castle level costs, which building has to be upgraded first, and what to ignore once you pass C30. The official numbers only cover the castle itself; the required buildings cost extra time and RSS.

C1–C35 from the official War and Order Facebook post; C36–C40 from WAO Planner. Base time is the build time before speed buffs (M = minutes, H = hours, D = days). Every level also requires the Wall.
After C30
- The first thing to unlock is the Azurite mine.
- The Ancient Ruins node gets a new Royal Challenge icon that rewards AZ.
- A great place to plan your next steps: WAOTools.
Skip Mystic College and High Technology (for now)
If you're not buying AZ packages, ignore these until you reach C35. The AZ they cost isn't worth the power you gain. The game changed how power works a while back, and these don't work as well as they used to. With the latest numbers it may be better to wait until C37 before starting Mystic College.
When to start High Technology depends on when the Drill Ground needs more AZ to upgrade than High Tech does to upgrade march size.
