Teching is the term used for researching Technological Advancements in order to gain any number of bonuses that affect your Dominion. Teching is often used for Converting strategies although can it also be utilized well by Explorers, and occasionally by Attackers. By building Schools, your Dominion will produce Research Points which can be traded in for a new tech once you have enough points. Teching is a slow strategy that enables your Dominion to have increased efficiency later in the round. It is very difficult to keep up with the top players if you decide to tech but by the end of the round, you should be able to grow more effectively than other Dominions around you that have not teched. An important thing to note is that most techers will only research a handful of Techs and will then R/R their Schools to another building (often Diamond Mines or Homes).

Currently, every Dominion receives 750 Research Points daily, provided that they always take a daily platinum bonus. As such, they will receive a 'free' tech on days 13, 26, and 39 even if no Schools are built and no attacking is done.

A Dominion's accumulated Techs can be viewed by casting Vision on someone.

Race Selection

Any race can be used to Tech although it is generally more efficient Races that will benefit most from Teching. Some recommended races are:

Building Selection

Teching requires the construction of Schools. Schools produce research points based on their total percentage of land:

Schools produces 25 research points each hour per 1% owned, up to a maximum of 750 at 30% owned (limit 1 per acre).

Schools generate an additional 125 research points per 1% owned when invading targets at least 75% of your size, up to a maximum of 2500 at 20% owned (limit 5 per acre).

General Information

Teching is a slow strategy, aimed to generate benefit later compared to equivalent non-teching strategies. A common use is to aim for a lot of mid to late-game efficiency when percentage-based bonuses have their greatest effects, e.g. +5 % platinum produced often peaks around conversion for a Converter, while -7.5 % platinum exploration cost amounts to a significant amount of extra platinum late in the round for explorers. For this reason, teching can be very useful for players who do not have much time to invest into the game early in the round, but wish to compete later on. New or inexperienced players may also benefit from teching. Also note that for multiple techs with the same bonus it is additive when it stacks i.e.: picking the tech Midas's Bargain gives you a +2.5% platinum production, whereas Midas's Fountain gives a bonus of +5% platinum production. Therefore when you unlock both of these then your total bonus is 2.5% + 5% = 7.5%.

Pros

  • Great efficiency can be enjoyed late round
  • Allows less experienced players to compete effectively late round

Cons

  • Slow; Techers make very little impact throughout the round, often coming up from below for Attacking or Converting strategies.
  • Planning required; having a broad idea of how many / which techs you desire and when to stop building schools or destroy them is very helpful.

Recommendations

  • Great for Converters and slower styles.
  • Inexperienced players

Formulas

Tech Cost

In order to unlock a tech other than one of the three entry points, at least one of its connecting techs in the tree must already be acquired.

The cost of each tech is determined by

 9500 + (100 * CurrentTechs)

where CurrentTechs is the number of techs the dominion has already acquired. In other words, the cost of each new tech is 100 more research points than the previous tech's cost.

Invasion RPs

The number of research points (RP) gained during a successful invasion is based on the day of the round, the attacker’s percentage of schools, the relative size of the target, and any wonder or racial bonuses.

If the target is less than 60% the size of the attacker, no research points are gained.

 Final RPt < 60% = 0

If the target is 60% or greater, first the base RP gain is calculated as

 BaseRP = Max (1000, DayOfRound / 0.03)


When the target is greater than or equal to 60% and less than 75%, the base RP gain is halved.

 RP60% ≤ t < 75% = BaseRP * 0.5
 FinalRP60% ≤ t < 75% = RP60% ≤ t < 75% * (1 + WonderBonusPercentage) * (1 + RacialBonusPercentage)


When the target is greater than or equal to 75%, the attacker's schools are taken into account before wonder and racial bonuses. The following two formulas provide starting values:

 BaseSchoolBonus = (125 * Min (SchoolPercentage, SchoolPercentageCap)) * 100

where SchoolPercentage is the attacker's percentage and SchoolPercentageCap is 20%.

 SchoolModifier = 1 – Min (0.75, Max (0, NumberOfRecentInvasions – 2) * 0.15)

where NumberOfRecentInvasions is the number of times the target has been invaded in the last 72 hours, excluding when the target overwhelmed the attacker.


The research points gained in the invasion is limited to 5x the attacker's land size and then added to the base production.

 RPt ≥ 75% = BaseRP + Min (BaseSchoolBonus * SchoolModifier), (AttackersLand * 5))
 FinalRPt ≥ 75% = RPt ≥ 75% * (1 + WonderBonusPercentage) * (1 + RacialBonusPercentage)


FinalRP60% ≤ t < 75% and FinalRPt >= 75% are rounded to the nearest whole number and will return with the slowest unit sent on the invasion.
