Faction trophies are purely decorative buildings that can be built after reaching a given rank in your Faction and learning the corresponding skill of Local_Leadership at a school of Natural Philosophy.
They are built directly, under the Self / Projects... / Decorative... / House... menu, and only 1 trophy for each level can be built by a player.
Local Leadership 0 (Skill) is required to build a Faction Trophy.
The costs are as follows.
