Improvement Point

From FinalEscapeWiki

Each dwelling or faction HQ has a maximum amount of storage capacity, which can be further increased through the use of special dwelling upgrade items. Each dwelling or HQ upgrade item requires a certain number of improvement points in order to be added to a building. The current number of available improvements points for a dwelling can be viewed on the Dwellings page. The current number of points for a faction headquarters is listed on the HQ page.

Adding Modular Shelving or Advanced Shelving to a dwelling costs 1 Improvement Point each and add storage to a dwelling.
