To complete this little series, I adapted the “training Tier 4” chart to give a complete overview of the dependencies when runecrafting your city buildings. As I haven’t runecrafted my own Musterfield yet, I am not sure how the dependencies will change, but for level *1, requirements are equal. Note that the Armory is a requirement for runecrafting your City Wall, but that the Armory itself cannot be runecrafted.

The Runecrafting chart:

Once again, no number=equal requirement, number alone=static requirement, number plus a minus sign=dynamic requirement. All buildings not mentioned here can NOT be runecrafted.
