Naval Base

Players in a clan pool their Oil to build Structures that benefit all clan members.

Players in a Clan can earn Oil (), a Clan-specific resource to spend on building structures that improve the clan Naval Base and which provide bonuses to Clan members. 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.

Shipyard facilities decrease the credit cost of ships of a particular tier by 10%. Any discounts on purchasing a ship will also apply to their sale; if a player buys and then sells the same ship while the 10% bonus is active, they will save 5% of the initial cost of the ship. If any other discount is active when the bonus is, they are not added together, but the larger one applies.

Future discounts for Tier IX-X ships are planned, but are not available in the current iteration.

Rostral Column

This structure won't currently do anything beyond standing testament to the glory and honor of a Clan that erects and can afford its currently nigh-impossible cost of 9,999,999. In future updates, this structure will receive its own function, and become more affordable.
