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.
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.
Facilities are constructed by smithwyrms, who become occupied when construction is happening. Only two smithwyrms are initially available. However, more smithwyrms can be purchased in the Castle Grounds screen for 250 
or 250 
each.
