Methodology
What the confidence badges mean
The same figure agrees across two or more independent community databases or guides, with no discrepancy we could find. The strongest agreement we track — still community-sourced, not official.
Matches a widely-used community table, but we have not corroborated it against a second independent source since the last check.
Sourced from a single community database or guide. Treat it as directionally correct but not yet corroborated elsewhere.
Filled in from a pattern in the surrounding data (e.g. extrapolating a cost curve) rather than a figure someone reported. Use with the most caution.
Data pipeline
Numeric tables (costs, times, levels, point rates, dates) are imported from public community datasets and community tables, then merged and cross-checked through our core JSON pipeline. Page copy is written here — we do not paste third-party descriptions, FAQs or lore, and we do not label each table with a single-source attribution line. Open-dataset credit (KingshotPro CC-BY) is the block below, once.
Our sourcing process
- Collect figures from multiple independent community databases and guides.
- Cross-reference for agreement; flag and investigate any discrepancy.
- Assign a confidence badge based on how many independent sources agree.
- Update the "Last checked" date when we recompile a table.
- Recheck against community sources after major patches or new hero generations.
Tables on this site use numbers, names, dates and short labels. Skill blurbs and page copy are written here; we do not paste third-party guides, FAQs or flavor text.
Open datasets
Some numeric tables are cross-checked against open community datasets, including KingshotPro (kingshotpro.com) published under CC-BY-4.0. Attribution is here, not repeated on every table. Page copy, hero summaries and guides remain original to this site.
Construction bonus presets
Named checkboxes on the building planner add extra construction speed and/or cost-down on top of the manual Power Panel fields. They are game facts we cite independently — not copied from another calculator's labels. Check a preset only if that source is not already in your typed Construction speed % / cost-down %. Time uses time ÷ (1 + total speed / 100). Community-cited values below should be checked on your Power Panel before you treat a plan as exact.
| Source | Speed | Cost down | Confidence | Notes |
|---|---|---|---|---|
| Groundworks | 10% | — | Community single | Community-cited assigned-officer bonus. Last checked 2026-08-30. |
| Kingdom vs Kingdom | 5% | — | Community single | Community-cited match-period construction speed. |
| Double Time decree | 20% | — | Community single | Treated as extra additive speed % in the same formula. Confirm against Power Panel if a decree uses a separate multiplier. |
| Saul (max skill) | 15% | 15% | Community single | Community-cited skill range is 3–15% speed and 3–15% construction cost. The toggle uses the max rank. For an exact Saul level, leave Saul unchecked and type Construction speed % and Cost down % from the Power Panel. |
| Gray Wolf (max skill) | 10% | — | Approximate | Wolf boosts construction; the exact Power Panel % is not well corroborated. Prefer typing your panel total if this disagrees. |
How to check construction bonuses on the Power Panel
Open Power Panel, note Construction Speed % and Cost Down % with each source off, then tick Groundworks, KvK, Double Time, Saul and Gray Wolf one at a time and record the delta. These presets are community-cited conveniences, so the rows stay Community single or Approximate — your own Power Panel numbers always win.
Progression plans
The Optimizer hub at /calculators/progression encodes five planner domains in one query string:
?plan=b:…|r:…|w:…|t:…|a:…— building, Academy, War Academy, troops, Alliance Tech row strings. Each segment uses the same encoding as that planner's?p=parameter.?label=— optional title shown on the hub and kept in the share URL.?vs=— a second encoded plan. The table is Plan B minus Plan A (resources and time).- Short path
/p/<encoded>redirects to the hub with?plan=. Optional?inv=food,wood,stone,ironis a read-only stockpile subtracted from combined food/wood/stone/iron. Per-planner inventory still stores in localStorage.
Hub totals re-run the same expand/total functions as the sub-planners at 0% speed and 0% cost-down. Named construction bonuses stay on the building tool. Scenario presets load encoded rows only; they do not add new game numbers.
Known data gaps
- Items catalog: we do not ship an items reference. Only a small slice of item pages are in core JSON, so there is no items planner or reference table until that catalog is added.
- Hero Hall room costs: the community tables we ship have no cost row for Hero Hall rooms, so Town Center chains that need Hero Hall appear as unmet gates instead of priced rows. We will not invent those costs.
- Troop T6+ (including T10/T11) training costs and Barracks/Stable/Range Truegold training multipliers are not in any structured JSON we import. The troop planner stays T1–T5.
- Regular (non-Truegold) building event points are not in the building JSON. KvK City Construction uses 2,000 points per Truegold building upgrade only.
- Kingdom timeline dates: Nexus snapshots list stage types, not a predicted calendar. We will not invent match dates.
- No weekly auto-commit data Action. Refresh is: update
src/data/core/JSON, bumpmanifest.lastChecked, add a changelog line, deploy.
Frequently asked questions
From multiple independently-maintained community databases, wikis and guides, compiled and cross-checked into the tables you see here. Numeric tables are also checked against open datasets such as KingshotPro (CC-BY-4.0) — see Open datasets below. We do not copy third-party guides or flavor text. Nothing here is official or checked in-game by us.
