Research

The Research Center tech tree: 290 nodes, one per research line, each with its per-level cost, time, and bonus.

Use it to look up what a research costs, what it requires, and what it gives. To draw the tree, see Research tree. To plan a full research path, see the Research calculator.

ResearchNode

queue is main for Growth, Economy, and Battle, and warAcademy for the six T11 and T12 categories, because the game researches the two groups in separate queues.

ResearchLevel

ResearchRequirement

A building entry such as Research Center 7 or War Academy FC 10 round-trips into buildings().find(id)!.levels. An unreleased entry does not resolve against research() by design, so the gap stays visible. No node uses it now.

//   { type: 'research', id: 'indomitable-wall', level: 1 },

Notes

Research costs use the same resources as building costs: Meat, Wood, Coal, Iron, and Steel. The latest T11 and T12 tiers also use Fire Crystal Shard and Refined Fire Crystal.

Bonus values

bonus is an array because a level can grant more than one stat. Most levels grant one stat. 9 nodes have levels with two stats, for example helios-infantry-training.

amount is the bonus that the level adds, not the bonus so far. totalAmount is the bonus up to this level. The amounts 1.25, 1.25, and 1.5 have the totals 1.25, 2.5, and 4.

For T12 nodes, value is the bonus up to the level, not the bonus of the level. exalted-shoulderguard has 3.00%, 6.00%, 9.00%, 12.00%, and 15.00%, so its amount is 3 on every level and its totalAmount is 3, 6, 9, 12, and 15. A Molten II line has 50 levels of 1, and a total of 50 at level 50. The rule for amount and totalAmount is the same for every node, so you can add up amount for any node.

Three bonuses of the Other stat hold unlock text such as Unlock XI Helios Infantry. They have no statKey, amount, unit, or totalAmount.

Stat keys

statKey is the stat name in lowercase kebab case, for example "Infantry Attack" gives infantry-attack. It is the same key in research(), skins(), experts(), vip(), and allianceTech(), so you can add up bonuses from different modules. Two names are written in the singular, so they map to the plural key.

Research time

Every level has researchTimeSeconds. The 15 lines with five levels, for example exalted-blunderbuss, upgrade instantly, so all 75 of their levels have researchTimeSeconds 0. The three Exalted capstones, exalted-infantry, exalted-lancer, and exalted-marksman, are placeholders that unlock once the five lines of the troop type are complete. They take no time.

Corrected spellings

Several prerequisite names resolve only after fixing spelling errors. The package corrects them with an explicit alias list. It does not use fuzzy matching. The node names keep the spelling shown here.

All 50 levels of molten-plating-ii use Infantry Health, as the rest of the Infantry Molten II lines do for their own troop type. The package gives Infirmary Capacity at all three levels of Ward Expansion III, as level 1 does.

Added prerequisites

• Each troop type's 4 tier 2 Molten X I items also require that troop type's Exalted capstone at level 1, next to their War Academy building gate.
• Tool Enhancement I also requires Tooling Up I at level 1, next to Ward Expansion I and Camp Expansion I.
• Each troop type's 4 tier 4 Molten X II items (Molten Blades II and so on) require that troop type's tier 3 node (indomitable-wall, starfire, or meridian-phalanx) at level 1.
• Each troop type's 4 tier 6 Molten X III items require that troop type's Solar Supremacy node at level 15.
