The below tables list Faction upgrades, intended mostly for Mercenary Builds, and listed by Tier (as we are limited to 4 upgrades per tier). These tables are sortable by "What it does" and "What it is based on". The "type" and "based on" inputs are simplified, they do not differentiate between building types. Also, for better sortability, they have also been reinterpreted: there is no plural form and "Building production" is listed as "Production from Buildings P(B); "Click Reward" > "Production from the clicks" P(click), so they can be sorted under "P".
Most upgrades do not have individual pages, but a few especially important or historical ones may have additional notes.
