Lithoid Necrophage with Aquatics! – Stellaris 1 -

This is really just an excuse for me to make a necrophage guide. The main species doesn’t need aqautic since they aren’t working worker jobs. Prepatents use aquatic though.


Hello! I’m Apollo. I’m here with a year 30 Necrophage rush build. I know I’m about 4 updates to late. But with the new Aquatics update I wanted to make a Lithoid Aquatic Necrophage build. But aquatic on the primary species isn’t the best.
Hopefully by the end of this week I’ll have a YouTube video on this build. When I finish it, it will be posted here and here. – [] 

The Main Idea

When the Dev Diary #229 was released. I got super excited for the release, now it’s here!
In my speculative theory crafting video I mentioned Lithoid Aquatic Necrophage, but I now realize it’s not the most viable. So I thought I’d just salvage what I had and make a Lithoid Necrophage build.
Necrophage Has always been a very powerful rush build. One of the main things is it’s colonies. Since you don’t need to make a colony ship or wait for the colony to develop to get them. It’s great for the early game. (I recognize culture shock, but there are ways around it.)
In general, This is just my take on a Necrophage build in 3.2 Herbert. Many different things from previous Necrophage builds. Mainly, Masterful crafters. This is an amazing civic. The Building slots, Even more CGs, trade value, And as a cherry on top a little bit of research.

The Build

Lithoid Necrophage with Aquatics! - Stellaris - The Build - A62E7B6FA
The build doesn’t differ to much from other Lithoid Necrophage builds. But there are some differences.
Primary species traits:
Lithoid, When converting pops on other planets. Habitability can be a ma*sive issue, and since
Necrophages don’t grow. Lithoid is a natural bonus. Also your leaders effective life span is 150-180
Necrophage, this is just apart of the origin. In general the trait is meh, but everything that comes
with the origin is amazing. Specialist pop output and reduced upkeep is really good, but no pop
growth makes this trait, in general, meh.

Intelligent. Since we want to tech rush cruisers by year 26, getting as much tech as we can is
Volatile exrections, Access to the damage and clear blocker cost edict. and little bit more EC early
game. This is definitely worth it.
Natural engineers, Since we want to tech rush cruisers by year 26, getting as much tech as we can
is crucial. Yes I copy and pasted, what are you going to do about it?
Unruly, Free pick lul.
Fleeting, Once again, free pick lul.
Prepatent species traits:
Industrious, Minerals is one of the jobs they will be working a lot, so yeah more minerals.
Aquatic, since they will be on Chattel slavery, they will be working exclusively worker jobs. This
a 10% To all of that, And since we won’t be moving them to other planets. This is just amazing for
only 1 trait point.
Charismatic, Necrophytes produce so much amenities that this is worth more than ingenious.
Non-Adaptive. Since they will be on our capital, this virtually gives no downsides.
Fleeting, Once again, free pick lul. No slaves can be leaders, so yeah free pick lul.
Necrophage, the crux of this build. The colonies, population manipulation (for rush builds.)
Specialist pop output, 2 starting species. Necrophage Will most likely always be an A – S tier
Starting system:
Sol system. Finding your guaranteed habitable worlds the earliest is crucial. Getting culture shock
over with the earliest is great. The planet size is fine, (Why paradox does hydrocentric need the
primary species to have aquatic.)
Militarist, Claim influence cost, no retreat and that ship fire rate is worth it.
Xenophobe, Purging, Star base influence cost, and Pop growth speed is worth it.
Materialist, Academic privilege Is by far the best living standards with slaves. +400% specialist
political power, 10% research from jobs. Is WAY better than utopian living standards.
Oligarchic for meritocracy and more influence, (Oligarchic is the best authority if you have a choice
between all of them)
Meritocracy, 10% specialist pop output. Unity, Research, alloys. The most important resources in
any game.
Masterful crafters, CG’s are a big part of this game, important for upkeeping Academic privilege.
The engineering rearch gained is on par with natural engineers, the trade value is nice. The
building slots are amazing.
Yikes that was long. But yeah this is the build.


1st Jan 2200
Disable the bureaucratic center, reduce clerks to the lowest possible.
Sell all food and CGs, buy minerals for a research lab.
Change policy to isolationist and civilian economy. We don’t need like any alloys early game, making CGs and selling them is very profitable.
S*rip your ships, Dismantle the crew quarters, and make a science ship. When your ships are done downgrading, disband them, we won’t use them and the upkeep can be removed.
Change your primary species’ living standards to academic privilege.
Change your prepatents’ slavery type to chattel slavery.
This is the tech priority for the first tech choice.
– Nanomechanics
– Geothermal fracking
– Build speed
– Biodiversity studies
– Planetary Unification
– Hydroponics farming
– Quantum Theory
– Global Energy Management
– Field Modulation
From here It’s just economy techs, don’t bother with military tech until you get cruisers.
So, let’s explain the starting system. Having Sol system is a trade off, A guaranteed 18 size planet but we do know exactly where our guaranteed habitable worlds are. Send your first science ship to these systems. These systems are Alpha centauri and Sirius. These systems will, if you have sol system. Will always have your guaranteed habitable worlds. Also send your construction ship there.

The circled systems have distinct stars, even if you don’t have sensors.
These systems will have your guaranteed habitable worlds.

1st Feb 2200
Set up a monthly transaction of selling all CG’s and Food you make monthly.
Make 2 armies when you have 200 minerals, (don’t buy them)
The second science ship you make will a*sist research on your capital.


Unity Isn’t complicated. Just Prosperity Into supremacy.
Building and district upkeep
Specialist pop output
Building cost
Clerk from habitation districts
Lithoid Necrophage with Aquatics! - Stellaris - Unity - 472E6B2EC
Technological ascendancy, This should always be your first ascension perk in 90% of games.
Ship upkeep and naval cap
Ship Build cost and speed
Ship fire rate
Command limit
Damage vs starbase

One vision, This is generally a good 2nd one if you can’t get an acension path progress. If you can go for an ascension path perk, do so. If not one vision.
One vision is good for economy, the amenities usage can free up some jobs. Governing ethics will generally make your pops happier thus increasing stability by around 3 – 5.
Mastery of nature is another, Since our planet is really small at the start. A few more districts can help. Only downside is the 200 influence cost, Influence will be used for claims, less claims is less space.

Capital world

Your capital world is the most important a*set to any rush build. Your capital will produce Tech, alloys, CGs, the likes. First the build order, the build order is really long. If and when you can buy minerals to keep the build order going!
Build order:
Research lab, open slot.
Research lab, replace bureaucratic center.
Research lab, replace commercial zone.
Industrial district.
Research lab, open slot.
Sprawling slums.

At this point if you ever get Neural implants. You want to make a city district and make a slave
processing plant. If not continue with this build order.
City district.
Research lab, open slot.
Activate volatile land clearance and attempt to get a environmental engineer.
Lithoid monoliths x2.
Industrial district.
Lithoid monoliths x2.
Industrial district.
Any blocker.
Industrial district.
Alloy mega forge, open slot.
Any blocker
Mining district
When your last industrial district finishes, change your prepatents’ slavery type to indentured servitude.
Job priority.
This is a bit complex, but if done correctly can significantly increase consistent efficiency, and I’m all about consistent efficiency.
Pre indentured is a point where you only want to focus on research and building an empire, marked around the end of your build order.
Post indentured is the point where you want to start to expand alloy production.
Prepatents pre-indentured. From top (highest priority) to lowest (lowest priority).
Mining jobs
Post Indentured
Worker jobs stay the same
The Necrophages pre indentured
At some point you wont have enough necrophages for all specialist jobs pre-indentured. Start limiting the lowest priority so the will work more important jobs.
At the start you will won’t have enough specialist jobs, so some of them will work worker jobs, use the prepatent pre-indentured worker priority.
Post indentured

Colonies are the second most important a*set in this build. After stellar culture shock, your colonies will produce alloys, tech, minerals. The strategy can differ based on the amount of pops already there.
For all colonies as soon as you get them change them to indentured servitude then social welfare.
Build order.
Admin center, Employ only 1 per planet until sprawl goes over cap
Replace agri district with mining district
At 7 pops make a industrial district, Don’t employ the metallurgist.
At 8 pops make a Mining district
At 9 pops move 1 Necrophage pop from your capital and upgrade the capital building
At 10 pops Make a research lab x2
Industrial district at 12
Industrial district at 14
Industrial district at 16
Chamber of elevation
After your prepatents are indentured and stellar culture shock goes away. Do this to transition into an alloy economy:
Change to militarized economy
Change planet designation to forge world
Disable all research labs and replace one of them with an alloy mega forge
And of course employ all metallurgists
Post indentured priority
Researchers (If you’ve maxed out metallurgists enable research labs until you have all pops employed)

Misc preparations

With around 500 research in year 15, getting cruisers shouldn’t be hard even without tech b lining.
If you have trouble with finding cruisers, check out my rogue rush guide and go to the section where I talk about tech b lining.
The techs we want are:
Reactor 3
Plasma 1
Kinetic gun 2
Shields 2
Fire control systems
Getting these techs by year 26 shouldn’t be to much of a problem but here a few more techs to improve the ships if you happen to get those early.
Improved cruiser hulls
Kinetic gun 3 or 4
Sensor 2 or 3 maybe even 4
Combat computer 2
Plasma 2
If you are unlucky enough to not get star holds, worry not! Just make 3 starbases and use them
along with your capital one for shipyards, don’t forget fleet academy.
Once your done making your first batch of fleets, make 2 of them into economy stations to collect
trade And make food with hydroponics bay.
Last few things:
Don’t forget No retreat or damage edicts
Unyielding admiral is another
Retired Fleet officer governor for build cost

War >:)

So, now we have the tech, shipyards, alloy production, fleet power boosters, and plenty of other preparations. But now, WE HUNGER. First, ship design. As always if you happen to get crystal hull plating, go for it. but otherwise this is what you need at the minimum.
Lithoid Necrophage with Aquatics! - Stellaris - War >:) - E1E1963F0
Make 2 fleets of 20 cruisers in the fleet manager. Find unyielding admirals. Start making the cruisers around year 26 so they are ready by 30.
Here’s a little trick, whenever you’re about to finish a ship, move it to the back of the queue. This will significantly decrease upkeep while building. This cans save hundreds of alloys and thousands of EC.
Also don’t forget armies, you only need like 300 army strength max
First, make sure you’re on supremacist and your rivaling them.
Claim all of there planets and any entrances to there empire. This will prevent other empires from stealing territory.
Actual WAR >:)
Make sure your fleets are in the system bordering the empire you are going to war with. Also make sure that in the system the fleets are right next to the hyperlane ready to jump.
If you’re fighting a player, keep the fleets together and wait until you fight and win to split them up.
If you’re fighting an AI, use 1 fleet to go around caping all of the systems and 1 to destory there fleets
Even after Herbet the AI can still be really weak.

After war

Once you’ve won the war, close borders to any empire that once border the empire you just destroyed. make science and construction ships, and claim whats yours!
Necro purge all of the enemies’ former pops and use your new found power to either tech rush for a megastructure in year 70 or conquer the rest of the galaxy.

Wrapping up

Over all, this is really just a necrophage in 3.2 build. It’s a little tough to follow but shouldn’t take to much trial and error to get it right. In general this is a very powerful build and can be used in most multi player games.
Hope you enjoyed and conquer many galaxies with this build. I’ve been Apollo, and goodbye!
