The Spirecrafts form a Minor Faction. They were introduced in the Light of the Spire expansion.

While more powerful than Starships, spirecrafts are below Golems, however they compensate by being far more versatile, plentiful and easier to acquire.


This minor faction has three different difficulties. If multiple difficulties are activated, the harder takes precedence.

The EASY version of this minor faction simply gives you the spirecrafts with nothing in the way of benefit to the AI. Consequently, your adjusted scored is also halved.

The MODERATE version of this minor faction gives you the spirecrafts at a vastly higher energy cost and without the ability to repair them (though the Martyr and Shield Bearer cannot be repaired on easy or hard either).

The HARD version of this minor faction gives you the spirecrafts at their base energy requirements with no repair restrictions. However, whether or not you choose to capture any spirecraft, the AI periodically launches large exogalactic strikeforces against you -- so you're highly advised to get some golems in order to survive.

Please note: the only thing that changes with intensity for Spirecraft (Hard) is the strength of the exogalactic strikeforces, and cranking this up high could result in an extremely difficult and/or annoying scenario.


These Spirecrafts can be produced from asteroids seeded around the galaxy via a Spire Mining Ship. When selected, a Spire miner can build mining enclosures upon asteroids, consuming it in the process. The enclosure must be built by supplying it with Metal and transform into spirecrafts upon completion.

There are different enclosures per asteroid type producing different quantities and Mark levels of different spirecrafts. Each asteroid kind can create almost all kinds of spirecrafts, but the mark of the produced spirecrafts depends on the rarity of the asteroid.

Players do not need to own the system the asteroid is located in order to mine it.


The asteroids are here ordered by crescent rarity and power.

Reptite Asteroid
Pysite Asteroid
Xampite Asteroid
Ebonite Asteroid
Adamantite Asteroid
Titanite Asteroid


Spirecraft Shield Bearer
This Spirecraft projects a powerful force field around it to protect itself and any allied ships. Any ships within the shield do not suffer any damage reduction to their attacks.
Spirecraft Ram
A specalized ship designed to destroy high health targets. Will ram itself into a single target, causing extreme damage, but also destroying itself.
Spirecraft Martyr
This Spirecraft has no guns, but instead has a large array of tractor beams. When this craft is destroyed all enemy ships within its tractor beam range will take massive damage.
Spirecraft Attritioner
While this ship has poor weapons, it makes up by dealing high attrition damage to all enemy ships in the system every second. However this ship will alert every single ship on the planet who will all attack.
Spirecraft Scout
Unique scouts that are perma-cloaked. However they move very slowly and will quickly lose health on a AI held planet that is a mark level above them. Better served as a recon unit to free up dedicated scouts than as a dedicated scout.
Spirecraft Translocator
Excellent all-around ship with translocating railguns.
Spirecraft Penetrator
Perma-cloaked ship that houses a extremely powerful cannon. The ship must be ordered to fire manually, and when it does it is unable to fire for thirty minutes.
Spirecraft Implosion Artillery
Long range artillery Spirecraft that deals damage to targets based on their remaining health, deals best damage against fully healed targets.
Spirecraft Siege Tower
A slow moving, low range, mobile battlestation. Can take a lot of damage and dish it out.
Spirecraft Jumpship
A expensive, small capacity, transport ship that can rapidly teleport through wormholes and systems. Suffers no attrition damage when out of supply, but the ship will rapidly expire within twenty seconds on a planet with a higher mark than the ship.
