A screenshot of the Workshop in actioon.

The Forbidden Workshop is a campaign feature available only to the Clan Skryre faction. The player can spend Food and Warp-Fuel to buy upgrades and abilities for certain Skaven units, unlock campaign-only Regiments of Renown, or construct Doom Rockets.

How it works

The Forbidden Workshop is accessed while viewing the campaign map, using a button in the bottom right of the UI.

The Clan Skryre player can pay varying amounts of Food and Warp-Fuel to obtain new abilities and buffs for Ratling Gun Weapons Teams, Warplock Jezzails, Warpfire Thrower Weapons Teams, Doom-Flayers, Doomwheels, and Skaven characters mounted on the latter two war machines (see: Doom-flayer (mount) and Doomwheel (mount)). Doom Rockets can be built and also upgraded in various ways. In addition, while upgrading units, special banners and equipment will be unlocked.

The upgrades are separated into four tiers that are unlocked when a set of conditions have been met for each one.
