  • Heroes manage your nation, command your fleet and play an integral part in Astronest.
  • Understanding what makes a good hero for a particular role is central to building a powerful nation.
  • There are two major categories of heroes: Planet Ministers and Fleet Heroes.
  • When you appoint one of your heroes as a planet minister, you get bonuses on all the planetary facilities according to the hero's govern stat.
  • You can not participate in a war without an active fleet commander in a ship.
  • The hero's Attack, Defense, and Leadership stat affect the fleet's attack, defense stats and its size.
  • The hero's profession and skill can influence a battle significantly.
  • To start with, you can hire 10 heroes. Crystals are required to increase the limit.
  • Since the 2.9.0 Update there is also a Hero Codex to see the hired Unique and Special Heroes.

Hero Attributes

  • The core attributes heroes have are: Attack, Defense, Govern, Leadership, Skill, Ability, Tron (Support/Battle)
  • Attack: The higher the number the stronger the attack, though many other factors are taken into consideration. The weapon's relevant attributes, the relevant ship type/level/fittings, the player's relevant research enhancement levels, and all relevant attributes from the opponent.
  • Defense: Essentially the higher the number the better the defense points contribute to increased durability.
    As above all the metrics are taken into consideration except in reverse.
  • Govern: A Planet Minister's Govern level effects all the facility outputs, and in essence the higher the Govern attribute is, the better Planet facilities will perform with the exception of Cosment production.
  • Leadership: This is a Fleet attribute which is measured in Energy units to determine how many ships a Fleet Hero can command. 
  • Skill: Rank A and S heroes have special skills that allow the hero to perform special attacks or defense functions.
  • Ability: Rank B, A and S Heroes have additional special capabilities which can be upgraded by Training LDs and Advanced Training LDs.
    Abilities can be upgraded by acquiring Training LDs from Campaign drops, Alien Raids, event packs, the LD shop and returning heroes when not hiring them.
  • Tron: There are two slots available. The top one is for Support Trons and the bottom one is for Battle Trons. Fleet Heroes and Planet Ministers benefit from different aspects of either type of Tron. Trons add to specific attributes such as Attack/Defense/Govern/Leadership, as well as Ability and Skill.
  • Unique Ability: Unique heroes have a second ability, the Unique Ability. Conceptually, the Unique ability will provide buffs to the surrounding fleet or planets, depending if it is a Combat or Govern hero. Unique heroes can be found through the Master Scout. Because Unique heroes cannot be duplicated the duplicates will be automatically converted to LDs.
