Earthbounds | Fabric

Enhance Minecraft's world with the addition of unique vanilla inspired features

Created by Klyser_






- Earthbounds requires Geckolib and Fabric-API

Minecraft: Caves and Cliffs update is known to be the biggest one yet, which added the much awaited cave biomes alongside brand new world generation and a few neat additions such as Copper and Amethyst Geodes.
While it was one of the most hyped updates in the game's history, I believe that it was also lacking in certain aspects. Those aspects being unique cave mobs and features that complement their implementation.

Earthbounds's objective is an ambitious one: add more diversity to Minecraft's underground world both when it comes to gameplay/overall game experience, and give existing ores new, creative purposes. This is achieved by adding new ore-themed purposeful mobs (called Earthen Creatures) and adding more variety to minerals' uses. World generation may also have some additions to accomplish the goal.


Below's a list of the features, which contain detailed spoilers for what the mod adds. Earthbounds has its own Advancements tab which, if you want to play without the use of this page, will aid you throughout your experience.





Pertilyo is a bat-like Earthen made of Copper and Cobwebs. The only place it can be found is in Dripstone Caves, beneath the Deepslate layer of your world.

It is completely neutral, as it will ignore anyone's presence and just go about its day. If there is one thing though that the Pertilyo hates, is torches. When this blind fellow senses a torch, it will fly towards it and proceed with its absorption. Once the torch is absorbed, the copper Earthen will begin producing excess Glow Grease, until it plops it out and drops onto the ground.

You may want to be careful when you travel around Dripstone Caves, since as little as two Pertilyos can quickly get rid of any torches you placed and create a perfect habitat for hostile creatures.

As this lil guy is made of Copper, it can oxidize. Oxidized Pertilyos tend to roost on ceilings more often than its fresh peers, and tend to behave quite strangely when there's a thunderstorm. They will frantically attempt going above ground, to try cleansing themselves of the oxidation. Once they do get above ground, they'll shut down and wait for a lightning to strike them to de-oxidize. Why does this matter to you? Well, if the Pertilyo gets struck by lightning while in its oxidation phase, it will drop a Pertilyo Rod.

Pertilyo Rod

The Pertilyo Rod is a rare item which can be two ways: Either by witnessing a Pertilyo's de-oxidation process, or through crafting with the use of 3 Pertilyo Fragments. These can be found both as a treasure in Abandoned Mineshafts and as a rare drop from Pertilyos. Once the Pertilyo Rod is crafted or obtained, you can craft The Flingshot.

The Flingshot + Shimmer Shell

The Flingshot is a versatile weapon which is created using two copper ingots, two strings, a rabbit hide, an amethyst and a rare Pertilyo Rod. There is a wide selection of ammo it may use, the current list including Glow Grease, Shimmer Shells and Flinging Potions. To use a Flingshot, hold it in your preferred hand and hold your desired ammo in your other hand. A Flingshot may be repaired at an Anvil using Copper Ingots.
Shimmer Shells are the most valuable ammo Flingshots may use: they are small explosive shells, which go off shortly after touching the ground. These are particularly effective against Earthen creatures.

Copper Bucks, Madder Bucks


Copper Bucks and Madder Bucks are two other types of ammo designed for the Flingshot.
The Copper Buck is a simple damaging Buck, effective against Earthen mobs. With a bit of luck, these can bounce off multiple creatures and deal a hefty amount of damage.
The Madder Buck is a small shell that upon impact, sprays mobs in an area with the "Rubia" effect. You can read more about it in the "Fossilized Rubro" section.

Flinging Potions

Flinging potions are potions which can be flung using a Flingshot. They behave similarly to Throwing Potions, and they are made by adding Amethyst Dust to a brewed potion.


The Flingshot has four unique enchantments which can be found:
- Precision (I-V): Improves the Flingshot's Accuracy
- Force (I-III): Makes the Flingshot's shots travel further
- Automation: Makes the Flingshot shoot automatically when fully drawn
- Versatility: Allows the Flingshot to fling item drops

Glow Grease

When exploring Dripstone Caves, you may come across splashes of Glow Grease. This is a special type of block, which makes any surface slippery. It also has an additional property: it emits light! 
Finding these usually means a Pertilyo was or is nearby.

Fun fact: Amethyst dust can be used or put in a dispenser to create a cloud of shiny particles!





Rubro is a neutral feline-like Earthen made of Redstone and Stone/Deepslate. It can sometimes be found near Redstone Ore veins and deposits underground.

Rubros tend to look for Redstone Ore to scrape with their claws, in order to charge themselves. Charged Rubros develop an innate sense of smell, meaning they will kill any foreign creature that's not made of Redstone. Additionally, they can tell if you've recently mined Redstone, meaning that no matter what you do they will try taking it off you through their hostility.

A hostile Rubro will quickly pounce at you, followed by them hitting you where your shield can't reach with its tail (They tend to aim at your feet - this means you might be able to avoid this attack by jumping at the right time). 


Rubros are completely neutral to players who are holding Redstone in either hand. Think of it as some "sign of peace", which however is broken if you even dare touching their precious ore.

Bottled Rubia

Lastly, right-clicking on a Powered up Rubro with a glass bottle allows to collect its rage and power, filling the container with Rubia.
Bottled Rubia can be tossed like a Bottle o' Enchanting, and any entity hit by the contents will attract Rubros and Fossilized Rubros attention.

Fun fact: Rubros despise witches! They can't stand the waste of Redstone they go through when making potions.

Fossilized Rubro

Fossilized Rubros are tameable Rubros, though they cannot be found naturally around the world.
Fossilized Rubros behave quite differently compared to their peers: they do not know how to dig up Redstone independently, requiring you to feed it to them for them to fully grow to their adult form. Alongside that, they are not aggressive and can be "deactivated" with a simple right click.

Though a Fossilized Rubro does not spontaneously attack things, it will become extremely aggressive towards anything with the new Rubia effect. Additionally though, Rubros are passive unless charged with Redstone (similarly to how normal Rubros behave). These little guys are powerful, and take 60% reduced damage from most sources.

Fossilized Rubros come in 12 variants, 6 being Stone variants and 6 being Deepslate variants.

Redstone Fossils
Redstone Fossils are new rare ore that can be found underground, at roughly the same depth as Redstone. When these are broken, they drop both their corresponding mineral (Gilded Redstone Fossil will drop Raw Gold for example), and Primordial Redstone.
Primordial Redstone is a new, powerless and ancient variant to Redstone that Rubros go crazy for. It can be used both to heavily power up a Rubro, and to heal it in case its withstood heavy damage. 
Default Redstone and Deepslate Redstone Fossils are common, while all other variants are 5 times more rare. Good luck finding your favorite one underground! And also, make sure to keep a Crumble III pickaxe with you to break the Fossil for a surprise ;).

Helpful tip: Fossils make creaking sounds when placed. You can use these creeks to help yourself finding them.


Rubia is a new status effect, which attracts the hostile attention of both Rubros and Fossilized Rubros. The only way to apply the effect is through a Madder Buck (scroll up to the Flingshot section for more information).

Fun fact: Even Fossilized Rubros despise witches! They will pounce them as soon as they lay eyes on them.


ezgif 3 289017ac18

Carboranea is a passive spider-like Earthen made of Coal and Diorite. They are quite rare, and can be found exclusively in their Coal Dens, above ground in Savanna and Mountain biomes.

They are simple creatures who like staying warm. This means that they will follow other warm-blooded creatures like yourself. They do that until they find a source of heat stronger than your body, in which case they will stay near it until they decide they are warm enough.

When particularly hot however, they tend to cool down by releasing small Coal Chunks, which are extremely hot and will harm anyone who touches them.

These hot coal chunks are way more useful than you may think: furnaces quickly pick up adjacent chunks of coal, and will use them as fuel.  With some effort, an automated system to provide furnaces with infinite fuel can be created thanks to Carboraneas. 

A Carboranea can also be fed with Blaze Powder, and may mate if it and its partner are hot enough. Though, it's been observed that they can do so only once every three days for some reason.

Fun fact: Carboraneas really love lava: as soon as they find some, they will dive in straight away. 

Lastly, Earthbounds (so far) adds one last feature: a new Pickaxe Enchantment "Crumble (I-V)".
When a pickaxe with this Enchantment is used to break a block, its drop may change. For example, breaking Stone Bricks with a Crumble Pickaxe will drop Cracked Stone Bricks. Try breaking Amethyst Clusters with a Crumble pickaxe! ;)
Additionally, a Crumble Pickaxe will deal additional damage to Earthen creatures (similarly to how Smite does for undead creatures).
Each level of Crumble will increase the damage dealt per hit, and will increase the likelihood of finding special drops when mining specific blocks.

Fun fact: A pickaxe enchanted with "Crumble" won't break any blocks in Creative Mode



Origin: Rubian

Earthbounds has an included Origins addon which adds a new Origin: Rubian!
It's an advanced Origin which can be very effective at exploring caves and in PvP. You can read more about it HERE


Got any questions?

Q: I found a weird ore underground which just drops itself... What's that about?
A: That... You will find out soon ;)

Q: Rubros keep killing me any time I reach the Deepslate layer of the world... What should I do?
A: Rubros do not like other beings that dig Redstone or who smell like.. themselves. Hold some Redstone in your hand and you will probably be fine... Just hope that they don't notice if you mined Redstone Ore in the past 5 minutes or so :/

Q: Why can't I block Rubro's attacks with a shield?
A: You can only block a Rubro's pounce. Its "spin attack" can be avoided by jumping when their tail is about to hit you.

Q: Why isn't the Carboranea I found producing any coal chunks?
A: It probably means its environment is not warm enough. Provide it with heat-providing blocks and it will begin heating up. Keep in mind though that in colder biomes, the Carboranea will take longer to reach critical temperatures!

Q: Does Earthbounds work in multiplayer?
A: Yeah, the mod works great in multiplayer.

Q: Can you make a <1.18 version?
A: No. That would require a LOT of time and effort since I am alone developing the mod. I'd rather focus on expanding the mod further for the current version.


Q: ...Forge?
A: Maybe. Once this update has become stable, I will start a mod rewrite in MojMaps, which will bring us one step closer to a Forge release.

Q: Can I include Earthbounds in X modpack?
A: Of course! Make sure though to credit me, similarly to how you'd credit other mod creators in the modpack.

Q: Can I make a video on Earthbounds?
A: Yup, make sure to credit the author (me) appropriately though! And maybe shoot me a DM with the link so I can take a look :)
