Not to be confused with the Under-City building.

Under-Cities are a special settlement type available to Skaven factions which can be established secretly underneath settlements owned by other factions. They are similar to the Pirate Coves of the Vampire Coast.

Under-Cities were added in the Doomsayers Update, due to popular community demand.

How they work[]

  • Under-Cities can be established by choosing the Expand Under-Empire settlement option after defeating a settlement's garrison.
  • Additionally, Warlock Engineers can establish Under-Cities as a hero action, without needing a battle. There will be a 10-turn cooldown before any engineer can perform this action again, and the gold cost will increase with each under-city established in this manner. This includes the under-city with Warlock Laboratory established by a DOOOOM! Engineer.
  • Under-Cities will be destroyed by razing the settlement entirely.
  • Under-Cities have their own buildings available for construction, separate to regular Skaven buildings. See Buildings section below.
  • Under-Cities have no garrison.

Discoverability[]

  • Under-Cities and the buildings they construct are invisible to all other factions as long as they are not discovered.
  • Most buildings in an Under-City increase the discoverability rating. Buildings in the Concealment chain decrease discoverability.
  • Certain heroes have the Discover Under-city passive ability, which will increase discoverability when such heroes are present in the region. Conversely, the under-city owner can deploy warlock engineers, which have the Conceal Under-city passive ability, in the region to decrease discoverability.
  • The higher the discoverability, the more likely the Under-City is to be discovered.
  • The under-city will be discovered when discoverability reaches 100. The settlement owner can then spend gold to destroy the under-city.
