Planet modifiers

Each planet has a small chance of containing a modifier that will affect the colony should the world be colonized. They may be positive, negative or mixed, identified by the color of the modifier's border.

Random anomalies can generate a great variety of planet modifiers but those usually do not have any effects.

Random modifiers

These modifiers can appear at random on any planet outside an empire's home system. Some of them can be removed if the planet is terraformed.

	Modifier	Effects	Spawn chance	Removed by terraforming	Description
	Bleak	−5% Habitability −10% Food from Jobs −2 Max Agriculture Districts	×0 if Tropical ×0 if  Lush	Yes	Life struggles to survive here, and while some clings to a tenacious existence it is anemic and sickly.
	Poor Quality Minerals	−25% Minerals from Jobs −3 Max Mining Districts	×4 if  Low Gravity ×0 if  Carbon World	No	It is unknown if this planet simply formed this way, or if some unknown race once stripped it of its more valuable resources. However, we do know that the minerals present on this planet are of unusally poor quality.
	Tidal Locked	−30% Max Districts	×3 if moon Always present on Proxima Centauri b	No	This world is tidally locked around its star, meaning that one side always has daylight while the other is locked in eternal darkness. If life exists here, it is likely limited to the twilight regions where the two sides meet.
	Weak Magnetic Field	−5% Habitability −5% Pop Growth speed	×2 if  Low Gravity ×0 if  Strong Magnetic Field	No	Although habitable, this world has a weak or non-existent magnetic field that offers little protection against cosmic radiation.
	Hazardous Weather	−10% Habitability −5% Happiness +20% Energy from Jobs +4 Max Generator Districts		Yes	This world suffers from unstable weather patterns, with violent storms frequently appearing out of nowhere to wreak havoc on the surface.
	Hostile Fauna	−10% Habitability −5% Happiness +20% Society From Jobs	×2 if  Lush ×2 if  High Gravity ×0 if  Titanic Life	Yes	This world has evolved extremely Hostile Fauna, and the surface is rife with lethal predators waiting to ambush their next meal. Their biology offers great research opportunities, however.
	High Gravity	+10% Building cost +10% District cost −5% Habitability +2 Max Districts	×2 if  Planet Size > 19 ×0 if  Planet Size < 12 ×0 if  Low Gravity	No	This planet is unusually dense and so has uncomfortably high gravity.
	Low Gravity	−10% Building cost −5% Habitability	×0.5 if  Planet Size >19 ×0 if  High Gravity	No	This planet has an unusually low density and therefore much lower gravity than most planets of comparable size.
	Wild Storms	−5% Habitability −5% Happiness +20% Physics from Jobs		Yes	Spectacular electrical storms wrack this planet's atmosphere on a semi-regular basis.
	Atmospheric Aphrodisiac	+5% Habitability +10% Pop Growth speed −20% Government ethics attraction		Tomb World Machine World Hive world	Something in the air of this planet seems to put people in the mood to reproduce.
	Carbon World	+15% Minerals from Jobs	×0 if not Barren	No	This world has been formed mostly out of carbon, and contains little oxygen.
	Exceptional Quality Minerals	+25% Minerals from Jobs +8 Max Mining Districts	×8 if  High Gravity ×0 if  Carbon World	No	The exceptional quality of the minerals in this planet's crust provides a truly staggering opportunity for mining.
	Extensive Moon System	+10% Minerals from Jobs +1 Max Mining Districts	×0 if not Gas Giant ×0 if no moons	No	This gas giant has an unusually large amount of natural satellites. Hundreds of small moons and moonlets orbit the planet.
	High Quality Minerals	+15% Minerals from Jobs +4 Max Mining Districts	×4 if  High Gravity ×0 if  Carbon World	No	An abundance of high quality minerals in this planet's crust makes mining here a lucrative business.
	Lush	+10% Habitability +20% Food from Jobs +4 Max Agriculture Districts	×3 if Gaia ×2 if  Low Gravity ×0 if  Bleak	Tomb World Machine World Hive world	Life thrives here, the fauna is plentiful and the flora grows rapidly.
	Natural Beauty	+5% Happiness +25% Migration Pull	×3 if Gaia	Tomb World Machine World Hive world	The scenery on this planet is simply beautiful, anyone living on this planet will be constantly finding new wonders to behold.

Terraforming candidates

Terraforming Candidates are modifiers that have a small chance to appear on uninhabitable planets and are always added to worlds ruined by a crisis. The modifiers allow the planet to be terraformed if the  Climate Restoration technology has been researched. They do not appear if the required expansion is not installed. The chance for the a planet to have the modifier is scaled by the Habitable Worlds game setting.

	Modifier	Planet	Chance	Required AP	Description	DLC
	Terraforming Candidate	Barren	1%	—	Though barren and devoid of life, this planet has water in frozen form and may once have been home to a thriving ecosystem. With the right technology, it could be terraformed into a habitable world.
	Frozen Terraforming Candidate	Frozen	1%	Hydrocentric	Though cold to the point of being unable to sustain life, the frozen water on this world could allow us to terraform it into a habitable world, if we can find the right method.
	Toxic Terraforming Candidate	Toxic	15%	Detox	Though the noxious gases on this world make it unfit for life, with enough effort they can be broken down into less lethal compounds, eventually allowing colonization.

Event triggering modifiers

The following random modifiers trigger an event roughly one year after the planet is colonized. The event can only trigger once per colony.

	Modifier	Effects	Spawn chance	Removed by terraforming	Event
	Irradiated	−10% Habitability −20% Happiness −50% Food from Jobs −6 Max Agriculture Districts +2 Max Mining Districts		Yes	Colony gains one of the following: 20% chance Ancient Bombardment Craters planetary feature 20% chance Ancient Battlefield planetary feature 20% chance Irradiated Ruins planetary feature 40% chance Uncertain History modifier
	Unstable Tectonics	−10% Habitability −5% Happiness +20% Engineering from Jobs	×4 if  High Gravity	No	Colony gains  −5% happiness for one year. There is a 66% chance for either the colony to gain a Deep Sinkhole blocker or for the empire to get 100-500  Minerals.
	Asteroid Impacts	−5% Habitability +5% Minerals from Jobs +2 Max Mining Districts		No	Colony gains  −5% happiness for five years as well as either  20 devastation or the Impact Crater planetary feature.
	Atmospheric Hallucinogen	+5% Biological and Lithoid Pop Happiness +10% Physics from Jobs −5% Worker job output		Tomb World  Machine World  Hive world	Empire gains a special project. Finishing it removes the modifier and has a 25% chance to add the Filtered Atmospheric Hallucinogen modifier with  +10% Happiness and +10% Physics from Jobs.
	Asteroid Belt	+10% Minerals from Jobs +3 Max Mining Districts	×0 if moon ×2 if  Low Gravity	No	Colony gains  +10% happiness for five years.
	Strong Magnetic Field	+5% Energy from Jobs +5% Physics from Jobs +2 Max Generator Districts	×2 if  High Gravity ×0 if  Weak Magnetic Field	No	Colony gains either +20% or −10%  Research from Jobs for five years as well as a special project. Finishing the special project adds the Magnetic Miracle modifier.
	Titanic Life	+25% Society from Jobs	×8 if  High Gravity ×0.5 if  Low Gravity ×0 if  Hostile Fauna	No	Empire gains a special project. Finishing it either allows the recruitment of Titanic Beast armies on the planet or have the colony invaded by 3 powerful armies. If the empire is  Xenophobe, it can choose to gain the Delicious Titans modifier instead of the special project.
