Upgrading a glyph building: At one time, before scientists fully understood the Halls of Vrbansk, it was necessary to actually build a Hall Building before a sacrifice could be made. Now the technology has been improved and you can upgrade Glyph Buildings directly (using the upgrade button).
You still need sufficient Hall plans before you can upgrade however. The number of Hall plans should equal the level of the building after you upgrade it. So, to upgrade a level 5 building you will need 6 plans.
To upgrade a permanent building with halls, click on the building, as you would any other, and click the 'upgrade' button. The correct number of hall plans will be deducted and the upgrade will be scheduled.
If you don't have enough hall plans for the upgrade, the button will not be displayed and you will have a message to that effect instead.
Buildings upgraded in this manner are also limited to level 30.
