Smithy research
Permanently sharpen your troops — +5% attack and defense per research level.
The Smithy system lets you upgrade each troop type up to research level 3. Research happens in the unit's own training building: infantry in the Barracks, cavalry in the Stable, and so on. Each level permanently adds +5% to that unit's attack AND defense stats — for that village.
How the cost works
Research is instant — there's no timer to wait out. The cost is the sink: each level is a hefty multiple of the unit's recruit cost, and higher levels demand a more developed training building.
level N cost = 10 × N × unit recruit costRequires the unit's training building at level 3 × N.
Costs per unit
| Level | Bonus | Cost | Building required |
|---|---|---|---|
| 1 | +5% | 10 × 1 × recruit cost | 3 |
| 2 | +10% | 10 × 2 × recruit cost | 6 |
| 3 | +15% | 10 × 3 × recruit cost | 9 |
Where it pays off
- Research applies per village — a new conquest starts back at level 0.
- Bonuses apply to units from that village wherever they fight, at home or abroad.
- It compounds with everything else: a wall behind researched defenders is far more than the sum of its parts.
Research the units you actually mass, not everything. Level 1 on your two workhorse units beats level 3 on a unit you field twenty of — the +5% only matters multiplied across a real army.
