Facilities
Facilities are structures that can be built in the Castle Grounds in Dragalia Lost. They are divided into three categories: Production, Adventurer, and Decorative. Production facilities provide resources over time, Adventurer facilities boost the stats of characters with their respective element, and Decorative facilities are only cosmetic. Only 2 facilities can be worked on simultaneously, since there only two smithwyrms.
The Facility Level is the sum of the levels of all facilities, including the Smithy. Increases the facility level can be a prerequisite for increasing the Halidom level.
To make space on the Castle Grounds, facilities can be moved into the Storehouse. All facilities in the Storehouse are inactive and retain their level progress. Note that if a facility has reached its building limit, moving it into the Storehouse does not allow more of that facility to be built.
