Clan Buildings

Clan buildings sit on the World Map inside clan territory and are built and upgraded by clan Leaders and Superiors. They convert city resources into clan resources used to upgrade clan structures and activate bonuses.

Members donate city resources to clan buildings via caravan — there is no tax on donations to clan buildings (unlike the 20% tax on player-to-player resource transfers).

How Donations Work

Tap or click a clan building on the World Map
Send resources via caravan from your city
Resources accumulate automatically in the Clan Capital — no manual collection needed
Each building has six efficiency levels based on how much resource is currently stored — keep buildings stocked for maximum output

Clan University

Converts Silver → Scientific Tractates (Red Books)

Scientific Tractates are required for all Clan Research in the Capital.

Stored Silver	Efficiency

> 4M	Level 2
> 7M	Level 3
> 14M	Level 4
> 30M	Level 5
> 60M	Level 6 (maximum)

Consumption: 300,000 Silver/hour (constant regardless of efficiency level)
Maximum per clan: 3 University buildings
Construction cost: 9M Lumber + 9M Iron + 9M Stone

Keep the University stocked above 60M Silver for maximum Tractate output.
