Espionage

Spy training, missions, detection odds and the limits on theft and sabotage.

Times are game time at world speed 1. On a faster world divide them by its speed.

Spies need rank 5 (Yeoman), the Spycraft research and a Watch House. Each costs 200 gold and 1 peasant and trains in 15m. They walk 9 cells per game hour before research and cards. How it all works is on the Espionage page.

Mission	Cost	Base catch chance	Villages only	Needs war
Infiltrate	150 gold	10%	no	no
Steal research	400 gold	20%	yes	no
Sabotage	300 gold	30%	yes	yes
Watch	200 gold	5%	no	no

Catch chance = base + 4% per spy at home (at most 10 count) + 15% with a Watch House + 10% at a held capital + the target's spyWatch research - the sender's spyStealth research, kept between 2% and 90%. A watching spy rolls again each game hour at 25% of its arrival chance.

Catch chance with no research on either side, by spies at home in the target village:

Mission	Watch House	0 spies	2 spies	5 spies	10 spies
Infiltrate	no	10%	18%	30%	50%
Infiltrate	yes	25%	33%	45%	65%
Steal research	no	20%	28%	40%	60%
Steal research	yes	35%	43%	55%	75%
Sabotage	no	30%	38%	50%	70%
Sabotage	yes	45%	53%	65%	85%
Watch	no	5%	13%	25%	45%
Watch	yes	20%	28%	40%	60%

Research theft takes 25% of the research's full time, at most 3 game hours, then the target is on guard for 24 game hours. Sabotage delays work by 25% of what is left, at most 30 game minutes; a fire takes 40% of the building's base time to rebuild, or 50% of its base cost to repair at once. A watch lasts 1 to 12 game hours.
