Thievery Formulas

Thieves Per Acre

The ratio of your TPA to your opponent's TPA will determine the success rate of your conducted thievery ops.

Raw TPA

Raw TPA = Number of Thieves / Acres

Mod TPA

Modified TPA = Raw TPA * Invisibility * Crime Science * Racial Mod * Thieves Dens Bonus * Honor Bonus * Ritual Bonus

Modifier Type	Active	Otherwise
Invisibility	1.1	1
Thievery Science	Check your science page

Stealth

The amount of stealth you use depend on what thievery operation you use and your relations with the opposing kingdom:

• Sabotage Operations (without relations) - 3%
• Sabotage Operations (Hostile or higher relations) - 2%
• Espionage Operations - 2% (excluding Spy on Throne, which is 1%)
• Failed attempts use 50% more stealth.

You need at least 10% stealth to be able to send your thieves out.

If you log on to find your stealth being much lower than you expected, someone has probably cast Expose Thieves on you. The spell will reduce your amount of stealth to 80% of what you had.

Stealth increases with 3% every hour (excluding personality or racial bonuses).

Thieves to Send

Optimal Thieves to Send = (Opponents' Resources * Max % Of Total) / Gains Per Thief / Racial Mod

• Opponents' Resources can be found by using the Spy on Throne thievery op.
• Max % of Total and Gains per Thief are given by the table below.

Thievery Yield

Thievery Yield = Thieves Sent * Relative Size * Gains Per Thief * (1 - Resources Lost) * Racial Mod


Relative Size = MIN ( Target Networth / Self Networth , Self Networth / Target Networth) + War Bonus

• Gains Per Thief is given by the table below.
• Resources Lost is given by the table below.
• Thievery Yield is reduced by up to 75% by watch towers.
