Hissho Leader

Heroes are powerful characters that provide great bonuses to your planetary Systems and Fleets. Heroes must be recruited and then attached to a fleet or system. While active, Heroes will gain XP, allowing them to access Abilities that improve their bonuses each time they level up to max level 20 (25 in Disharmony).

Every Hero has two Classes out of the five total (Commander, Corporate, Adventurer, Pilot and Administrator), which determine the Hero's starting attributes and their access to special abilities. The five attributes (Melee, Offense, Defense, Labor and Wit) give bonuses to FIDS 1025fidsSmall.png production or combat actions. Heroes accumulate XP every turn they are attached to a Fleet or System and even more when they engage in battle. Every time the Hero levels up, you can unlock one Ability for that Hero.

There is a limit on how many Heroes can be used by an empire at any time, the so called "Academy Cap", which can be increased by researching the tier 7 technology Futuristic Game Theory (+2 Academy Cap) and tier 9 technology Perfect Forecasting (+3 Academy Cap) on the Diplomacy & Trading Technology Tree. There is a Dust 1004moneySmall.png cost to recruit a Hero as well as a 1004moneySmall.png upkeep that must be paid each turn.

Recruitment and Expelling[]

Heroes are recruited out of a Recruitment Pool, that initially consists of 3 randomly chosen Heroes for the faction. Every 50 turns, another Hero is added to that pool. This interval can be influenced by Research.

The 1004moneySmall.png cost for recruiting Heroes depends on the number of Heroes you already have in your service.

No. Heroes 0 1 2 3 4 5 6 7 8 9 10
Hiring Cost (1004moneySmall.png) 20 80 140 200 260 320 380 440 500 560 620

The upkeep cost of Heroes is equal to twice their level. When you fire ("expel") a Hero, they become available to every Empire still in the game (this implies that the initial Hero pool is not shared between the different Empires).

Heroes can gain experience and level up. Each level gives 1 ability point, which can be spent to unlock Abilities. XP requirements are as follows:

Level Total XP XP from previous
1 0 -
2 10 10
3 20 10
4 40 20
5 80 40
6 120 40
7 160 40
8 200 40
9 250 50
10 300 50
11 360 60
12 420 60
13 500 80
14 600 100
15 700 100
16 800 100
17 900 100
18 1000 100
19 1100 100
20 1200 100

The XML suggests the following values for XP gain; however, there appear to be some hidden modifiers:

Source XP
Assigned (per turn) 1
Completed construction 1
Won battle 20
Drew battle 10
Lost battle 5
Injured enemy Hero 20

In reality, Battles vary greatly in the number of XP they award, and depend on the ships destroyed. In addition, the construction XP bonus is related to the resource cost of the improvement. An exploitation gives 3 XP, for example. 


There are 5 different stats that give bonuses to the Star System or Fleet the Hero is assigned to. All stat bonuses are per point (for example, a Hero with a Labor of 5 would give bonuses of +10% Food 1001foodSmall.png and a +10% Industry 1002industrySmall.png).

  • +5 Defense on Star System
  • +5% Defense on Star System
  • +10% Invasion Military power on Fleet
  • +4% min Damage on Fleet Weapons
  • +4% max Damage on Fleet Weapons
  • +4% Intercept Evasion on Fleet Weapons
  • +4% Military power on Fleet Weapons
  • +4% Interception Accuracy (Flak)
  • +4% Absorption (Beam)
  • +4% Deflection (Kinetic) per turn
  • +4% Military power on Fleet Defenses


Main Article: Abilities

Abilities are traits of Heroes that change the attributes for a hero, allowing the hero to benefit the system or fleet they are located in.


A Hero attached to a Fleet who is defeated in Combat becomes injured. A Hero attached to a Star System is injured when the system is lost. Injured Heroes can not be used until they are healed. You can pay 1004moneySmall.png to heal the Hero. This 1004moneySmall.png cost is reduced each turn. The 1004moneySmall.png cost will decrease to 0, and you can start using the hero again.

Some effects reduce the 1004moneySmall.png cost to heal your Heroes, including the Hero Ability Hardy Constitution, as well as your racial picks. 


Horatio - Administrator Commander Hero

One of the traits of Horatio is "Cloning", which gives the ability to copy an existing Hero. The copy has the same Abilities, attributes and the same XP as the original. It is possible to clone a clone but clones count towards your Academy Cap. The 1004moneySmall.png cost for cloning is the same as for hiring a Hero.

Hero Capacity (Academy Points Cap)[]

There is a limit to the number of heroes you have under you command at any given point in time. As you research further into the tech trees additional heroes can be hired from the academy.

Technology Unlocks (research cost) Hero Limit Turns / New Hero XP Bonuses
Starting 3 50 0
Improved Fleet Management (300) -5 turns +20%
Futuristic Game Theory (7,500) +2 -10 turns
Maximized Exploitation (14,000) -5 turns +50%
Perfect Forecasting (25,000) +3 -10 turns
