Buildings
Nineteen buildings, thirty levels each, all gated by your Castle. Click any of them for its full per-level table — costs, build times, production and power.
Castle
Available from the start
The heart of your kingdom. Every other building is gated by its level, and each upgrade reshapes your city's skyline.
Wall
Available from the start
The kingdom's first line. Second only to the Castle in cost — it gates every siege.
Lumber Yard
Available from the start
Produces Wood, one half of the primary cost pair for every upgrade in the game.
Farm
Available from the start
Produces Wheat — the other half of the primary pair, and the food every army trains on.
Stone Farm
Unlocks at Castle 10
Quarries Stone, which castle upgrades start demanding from level 11.
Mine
Unlocks at Castle 15
Mines Metal, the scarcest building material. Castle upgrades need it from level 16.
Resource Depot
Available from the start
All production deposits here until you collect it. Levels raise the cap.
Barracks
Unlocks at Castle 2
Trains Warriors — the front line that soaks damage for the rest of your march.
Range
Unlocks at Castle 5
Trains Archers. They tear through Mages, but break against a Warrior charge.
Wizard Tower
Unlocks at Castle 10
Trains Mages, who counter Warriors and fall hardest to massed Archers.
Stable
Unlocks at Castle 7
Trains Cargo riders, who carry plunder home from a march.
Rally Hall
Unlocks at Castle 2
Musters your army. Every level raises how many troops may march at once.
Hospital
Unlocks at Castle 7
Wounded troops recover here instead of dying — up to the ward's capacity.
Research Lab
Unlocks at Castle 4
Permanent kingdom research: stronger troops, faster building, lasting boosts.
Hero Hall
Unlocks at Castle 5
Your lord's seat: forge gear, spend talent points, earn lord experience.
Adventurer's Outpost
Unlocks at Castle 6
Sends marches against monster camps for crystals, lord XP and mystery boxes.
Watchtower
Available from the start
Scouts rival castles. Every level sees deeper into their army.
Shield Generator
Available from the start
Raises a barrier over your castle. While it holds, no one can scout or attack you.
Kingdom Bank
Unlocks at Castle 20
Invest resources over time and draw Kingdom Coins back out. An endgame institution.
