Espionage is when you send your spies to take actions against a target in so-called spy-ops.
Spy-ops to obtain information about other dominions. Each info-op takes 2% spy strength.
|Barracks Spy (BS)||Gives an overview of the target's army and see units home defending (turtling), units out on attack and units in training.||Barracks Spies are important to attacking. They can also be used in place of Clear Sight if the target has impenetrable wizards.
It is important to know that all numbers except units in training are only 85% accurate (15% inaccurate) and that subsequent BS, even during the same hour, will return different numbers.
|Castle Spy (Ca, CS)||Reveals the target's castle.||Bonus from Masonries is included and does not need to be calculated manually.|
|Survey Dominion (SD)||Reveals the target's buildings.||Surveys also reveal incoming buildings and barren land. Surveys do not show of what land types the barren land consists.|
|Land Spy (LS)||Reveals the target's land types.||Only useful when calculating DP of Gnome, Sylvan, and Icekin when an SD shows barren land, so that you can assess how much of that barren land is the land type the race's units rely on for DP.|
Spy-ops to steal resources from other dominions. You can only steal from dominions which are the same size as you or larger. It costs 5% spy strength per resource theft op.
|Steal Platinum||Steals platinum from the target.||Platinum theft is limited to 2% of the target's platinum per op.
Platinum theft is also limited to 75% of your own raw platinum production.
Each spy can at most carry 45 platinum.
In order to count towards Spy Success and the Platinum Thievery rankings, 5000 platinum per op is required.
Note that Forest Havens may reduce the amount of stealable platinum.
|Steal Lumber||Steals lumber from the target.||Lumber theft is limited to 5% of the target's lumber per op.
Lumber theft is also limited to 75% of your own lumber production.
Each spy can at most carry 50 lumber.
In order to count towards Spy Success and the Lumber Thievery rankings, 2000 lumber per grab is required.
|Steal Mana||Steals mana from the target.||Mana theft is limited to 3% of the target's mana per op.
Mana theft is also limited to 56% of your own mana production.
Each spy can at most carry 50 mana.
In order to count towards Spy Success and the Mana Thievery rankings, 1000 mana per op is required.
|Steal Food||Steals food from the target.||Food theft is limited to 2% of the target's food per op.
In order to count towards Spy Success and the Food Thievery rankings, 2000 food per op is required.
|Steal Ore||Steals ore from the target.||Ore theft is limited to 5% of the target's ore per op.
Ore theft is also limited to 68% of your own ore production.
Each spy can at most carry 50 ore.
In order to count towards Spy Success and the Ore Thievery rankings, 2000 ore per op is required.
|Steal Gems||Steals gems from the target.||Gem theft is limited to 2% of the target's gems per op.
Each spy can at most carry 50 gems.
In order to count towards Spy Success and the Ore Thievery rankings, 500 gems per op is required.
Offensive spy-ops to cause damage to other dominions. They cost 5% spy strength per op.
|Assassinate Draftees||Kills some of the target's draftees.||The amount of draftees killed depends on yours and the target's Spy Ratios.
In order to count towards Spy Success and the Military Assassin rankings, 50 draftees per grab must be killed.
In case of mutual war, 50 draftees must be killed in order to gain prestige.
|Assassinate Wizards||Kills some of the target's wizards.||This operation kills wizards but not ArchMages, Dark Elf Adepts or Sylvan Dryads. The amount of wizards killed depends on the involved parties' SPA and the target's wizards. Only available during war.|
|Magic Snare||Reduces the Wizard Strength of the target.||This op can be devastating if highly concentrated, preventing the target from casting spells. On average, the target loses 2-3% Wizard Strength per successful op. Only available during war.|
|Sabotage Boats||Sinks some of the target's boats.||The amount of boats sunk depends on how many boats are protected by docks, the involved parties' Spy Ratio and how many boats the target has. It is uncommon for one dominion to be able to sink another dominion to a point where the target cannot send out his forces anymore. On average, 2-3% unprotected boats per grab are sunk. It is common practice to cast Great Flood on targeted dominions to slow their boat regrowth. Only available during war.|
The spy ratio or Spies Per Acre (SPA) is a significant factor in the success of spy-ops. If your SPA is higher than that of your target, you are more likely to succeed with spy-ops against them.
For other races, an SPA of 0.4 to 0.8 is usually sufficient to be consistently overall successful with info-ops.
Spy strength is another contributing factor in spy-ops success. It starts out at 100% and decreases with every op performed.
Spy strength refreshes by 4% per hour.
The chance of success is determined through one of two formula. See Ops Formula.
