Industry

Industry is a FIDSI resource used by cities to carry out the production of units, city improvements, expansions, and more.

A few factions have unique interactions with Industry:
 * The Wild Walkers gain +1  on terrain with Forests during Summer due to their "Living Towns" trait.
 * The Morgawr gain +2  on terrain with Sea or Lake and +1  on terrain with River due to their "Hydrophilic" trait.

Production
These are the primary ways to produce additional Industry in a city or across the empire.

Basic Terrain
Of the basic terrain types Forest, Rocks, and Volcanic terrain provide bonuses to Industry, though the amount can vary. For forests the Cold Forest, Crystal Forest, Palm Trees, Taiga, and Temperate Forest all provide 2, while the Enchanted Forest, Mountain Forest, Savanna, and Wetland provide 1. All Rocks except the Crystal Field and Crystal Ice provide 1. For Volcanic terrain, the Ash Drifts, Badlands, and Lava Swirls provide 1, Barren Soil and Basalt Plains provide 2 , and the Scorched Wilds provide 3.

Lava Flows provide +1 on tiles they pass through in addition to the tile's normal output.

Anomalies
Anomalies on a tile provide an additional bonus to its FIDSI output, and there are a number of anomalies that provide a bonus of 2, 4, or 6 on a tile.
 * 2 : Caldera Lake, Dragon Tree, Geothermal Pit, Golden Tree, Igloo Larvae, Lava Geyser, Massive Tree, Ruby Cactus Fields, Steppe Soil, Weaver Worms, and Wizard Stone
 * 4 : Clay, Earth Tower, Geysers, Meteor Fields, and Rumbling Stones
 * 6 : Fumarole, Mineral Rich, Spiral Rock Peel, and Steel Stalks

City Improvements
This list includes any City Improvement that increases a city's Industry output, even indirectly. Some of the improvements listed have additional effects that do not affect Industry production, but for simplicity those effects are not listed.

Expansions
Again, while many of these expansions have other effects, only those affecting Industry production have been listed.

Approval
Approval in a city has an effect on the generated Industry as well.

Heroes
Heroes provide a number of ways to increase the Industry output of a city they are the governor of, whether that be through capacities, skills, or accessories.

Capacities
As an additional note, the Sway of the Master can be equipped on heroes to give them the Slavery capacity.

Accessories
All listed accessories are Tomes.

Empire Plan
Tier 4 of the Science and Industry branch of the Empire Plan grants a bonus of +2 on Districts.

Resource Boosters
A number of Luxury resources (and Strategic resources for the Vaulters and Mezari) can be used to increase empire-wide Industry production.

Stockpiles
Industry Stockpiles can be applied to cities for a lump-sum quantity of Industry at the end of the turn.

Technology
The only technology that increases Industry output directly without the need to build a city improvement is the Era IV technology Endless Alloys, which increases the Industry output of cities by 100%.

Cost Reduction
Aside from simply producing Industry, there are also a number of ways to reduce the cost to produce buildings and units, though these methods often focus on one or the other.

These multipliers stack additively in the vanilla game, so you could reach 100% cost reduction for buildings. With ELCP, the stacking is multiplicative, making 100% cost reduction no longer possible.

Building cost reduction

 * +33% from the level 2 Science and Industry Empire Plan.
 * +12%/+24% from Behemoth Tamer (Wild Walkers hero skill).
 * +5% per pacified Urces village in regions when assimilated (up to 30%).
 * +25% from Wild Walkers quest technology Growing Buildings.
 * +20% for Districts from Industrial Megapole.

Unit cost reduction

 * +12%/+24% from Slave Driver (Necrophages hero skill).
 * +12%/+24% from Game Theory (Roving Clans hero skill).
 * +10%/+25% for naval units from Ship Builder (Morgawr hero skill).
 * +10% for naval units and +1% per Fortress from Naval Architecture Facility.
