Naval Bases provide bonuses to a Clan and its members, depending on which structures the Clan has built. There are a variety of structures available, including options for increasing the experience gains in ships of each nation, reducing the service costs of specific ship classes, and providing a discount on purchase costs of specific ship tiers. Each of these structures is purchased using Oil.
• Each victory in Clan Battles will add 30 Oil () to the Clan's stockpile. The maximum that can be earned is 90 Oil () per member per day.
While any member can view the list of structures and their bonuses, only clan members given the role of "Builder" can build structures. Ten (10) types of structures are ultimately planned, with five (5) available in the first version. Each structure type modifies one in-game parameter. Structures are marked with special flags in order to indicate which ship type a certain structure type affects. The Clan's "Builder" opens flags by spending Oil. Opened flags make the structure's features available for the group of ships indicated on the flag, and a structure's current flags are indicated on its icon.
