Buildings

Buildings stand on the plots of a stronghold (one plot per level) and are raised one level at a time. Most stand only on the ground; the vaults, the Builders' Guild and the Muster Hall can also be built on a Skyhold, and the Sky Keep, Scrying Spire and Waygate only there. Costs grow by the building's factor with each level. See Building, study and muster for how build times and queues work.

All numbers are for a 1× world before any bonus.
