Leader

Version

This article is considered accurate for the current version (2.3) of the game.

Employed leaders

A leader is a named character that leads a significant part of the Empire, as Governor, Scientist, Admiral or General. The ruler is a specific subtype of Leader and in many cases elected from the existing leaders.

The name of a leader can be changed at any time by clicking on it.

Gaining and losing leaders

All values in this section can be modified by leader traits, edicts, technology, policies, traditions, civics and ruler traits.

Leaders other than Rulers may be dismissed at any time. Dismissal is irreversible.

Leader pool

While some events and diplomatic options may give leaders, the most common way to get leaders is to recruit them from the leader pool. There is one pool for each type of leader, other than Rulers, who cannot be recruited directly. The default size of the pool is 3, but this can be increased by the Meritocracy or Pooled Knowledge civics.

A leader can be recruited from the pool for a base cost of 200 energy credits, modified by the following:

Source	Cost
Eager leader trait	-50%
Newboot leader trait	-50%
Adaptive Bureaucracy technology	-20%
Selected Lineages Leader Enhancement policy	+50%
Capacity Boosters Leader Enhancement policy	+100%

When a leader is recruited, a replacement in the leader pool is generated immediately. Thus, it is possible (though potentially expensive) to "re-roll" leaders in the pool by recruiting and immediately dismissing leaders. Alternatively, leaders in the pool are replaced automatically after 10 years.

Once recruited, leaders can be freely assigned to different posts (for example, moving a governor from one planet to another sector), be left without an assignment, or be dismissed.

Each Leader save for the Ruler has a monthly upkeep of 2 Energy Credits. For every one point of empire size over administrative cap the leader cost and upkeep increase by 1%

Age

Each leader has an age in years, which is between 28 and 50 when they are first generated (18-26 for heirs). Leaders have a base guaranteed lifespan of 80 years. Life expectancy can be improved by picking the traits Enduring or Venerable during species set-up and by researching certain technologies, picking certain traditions; or worsened by picking Fleeting during species set-up. Synthetics and certain other cases can make a leader immortal. Certain event resolution choices can also grant an increase in lifespan for all leaders.

After passing their guaranteed lifespan, leaders have a chance of dying every month. The probability is 0.2% per year that has passed since their guaranteed lifespan. After 20 years past their guaranteed lifespan this increases to 2% per year. The mean lifespan with no modifiers is 88 years, 6 months.

Hovering over a leader's age will show the species' guaranteed lifespan. Leaders that have the Mechanical, Machine and Chosen One will never die from old age. The same is true for rulers with the Hive-Minded trait.

Skill level

The skill level of a leader determines their basic bonuses, which depend on leader type (ruler, governor, etc.). By default, skill ranges from a minimum of 1 to a maximum of 5. The skill cap can be increased to a max level of 10 through certain traits, civics, and the leader enhancement policy.

A leader's skill increases after accumulating a certain number of experience points, shown in the table below. Upon gaining a level, a leader's experience total resets to 0 and they have a chance to gain a leader trait. A leader who has previously gained a trait from leveling cannot get another trait from leveling. Leaders who already have three or more traits and scientists researching technologies cannot gain a leader trait by leveling. The restriction on scientists can be circumvented by assigning them to another task, such as surveying or assisting research, right before they hit the required experience points for the next level.

Level	II	III	IV	V	VI	VII	VIII	IX	X
XP	200	475	825	1250	1750	2325	2975	3700	4500
Trait gain chance (admirals and scientists)	10%	14.3%	21.7%	35.7%
Trait gain chance (generals, governors, and rulers)	20%	27.3%	38.5%	55.6%

Leader classes

Leaders are divided into 5 classes that determines their possible assignments, bonuses, experience sources and available traits.

Class	Bonus per level	Experience gain	Assignment	Notes
Ruler	+5% Edict Duration +3% Monthly Unity	5 per month	Empire	Rulers are assigned from leaders based on an empire's Government type An empire's first ruler can be customized at empire creation but its traits are randomized When a ruler steps down it can be reassigned based on its class but loses all traits
Governor	+2% Resources from Jobs -3 Crime	5 per month when governing	Sectors	Governors can be killed by events if a planet in their sector has the Mob Rule modifier
Scientist	+2% Research Speed +1% Research Assist Output +10% Survey Speed	3.5 per month when leading research 3 per month when assisting research 10 per survey 50 per researched anomaly 100 per completed special project 75 per archaeology site chapter	Research departments Science ships	Research in a department is reduced by -25% if no scientist is assigned to it Science ships cannot perform any function without a scientist (except exploring wormholes) Scientists can gain new traits from anomalies A scientist's level is matched against the level of an anomaly when investigating to determine the time it takes to research it Scientists can die during archaeology site events if their level is too low
Admiral	+3% Fire Rate	5 per month when suppressing piracy 5 per space battle 0.5 per destroyed ship on either side 0.25 per disengaged ship on either side	Military Fleets	New admirals can arise after space battles Admirals can gain new traits based on what the fleet is doing Admirals have a 10% chance to die each time a ship of the largest size in the fleet is destroyed
General	+5% Army Damage	100 per ground battle 0.25 per destroyed army on either side	Planets Transport fleets	Generals have a 5% chance to die each time they lose an army

Leader Traits

Non-Ruler Leaders are generated with one pre-existing trait suitable for their class.

Every time a Leader gains a level, they have a chance to receive an additional trait, unless they:

• are a Scientist leading research.
• already have 3 traits
• have already gained a trait via level-up

Death by accident

While Mechanical and Machine leaders are immortal they can still die by accident, regardless of their age. Every 10 years there is the following chance of a leader suffering an accident and dying:

• 88%: nothing happens
• 2%: Survey Ship scientist dies
• 2%: Engineering Research Leader dies
• 2%: Society Research Leader dies
• 2%: Physics Research Leader dies
• 2%: Admiral commanding a fleet dies
• 2%: Governor governing a sector dies

There are two possible accidents for each leader class, both irreparably damaging it.

Note that this is rolled per empire, not per leader. For a role with exactly one leader, this represents a mean active lifespan of 500 years.

The Self-Preservation Protocols Tradition reduces the weight of accidents by half, reducing the chance for an accident to occur for each role to 1.06% (6.38% total), for a mean active lifespan of 940 years. The Tradition is only available to Machine Intelligence empires.

Unique Leaders

A few leaders can be obtained through events and, unless the empire's main species has traits that give unique bonuses to leader classes, are usually superior to regular leaders.
