What are the benefits of Level 12 buildings?
With the addition of Level 12 buildings it is now possible to make your City even stronger. At this point in time, Officer's Quarters and Muster Points are the only buildings that can be upgraded to Level 12.
Please keep in mind, like Level 11 buildings, each Level 12 building requires one Ancestral Seal to upgrade. In other words, to upgrade both your Officer's Quarters and Muster Point to Level 12 you will need two unused Ancestral Seals.
When you upgrade your Officer's Quarters to Level 12, you will be able to appoint 15 Generals.
A Level 12 Muster Point allows players to send up to 140,000 troops per march and send up to 12 marches.
