What is The Undergarden?
2 parts
The Undergarden adds a dark underground dimension that sits deep below the Overworld's bedrock. Plants there have adapted to the darkness and grow anywhere, with no light needed. The locals are strange creatures, and they are plagued by the Rotspawn, invasive monsters from a chaotic, mysterious realm. If you enjoy exploring a whole new world, building in it and surviving whatever lives there, this mod is for you.[1]
- 15 biomes to explore, plus 1 dungeon.[1]
- Over 10 unique entities and over 10 music tracks.[1]
- Ores with special properties when you turn them into tools and weapons.[1]
- 4 special potion effects, and over 10 advancements to guide you along the way.[1]
Getting there
Your ticket in is the Catalyst. Build a frame shaped like a Nether portal from Stone Bricks or Deepslate Bricks, then right-click the inner bottom of the frame with the Catalyst to light it. Once you've been down there, bricks made from Undergarden materials work for the frame too.[1]
In the pack, the Undergarden quest chapter starts with a quest in "?", which asks you to get the Catalyst. That makes it the natural first goal.[2]
Where it fits in All the Mods 10
All the Mods 10 4.5 ships The Undergarden 0.9.3 for Minecraft 1.21.1.[3]
The pack's Undergarden chapter works like a tour of the dimension. It has quests for the local food and plants, such as Underbeans, Blisterberry and Gloomgourd, plus saplings, mushrooms and the Slingshot. It also covers the four metals: Cloggrum Ingot, Froststeel Ingot, Utherium Crystal and Forgotten Ingot, each followed by quests for its tools or armor.[2]
Those materials also count toward the pack's general progression. The basic armor chapter includes quests for Cloggrum, Froststeel and Utherium armor sets. It also asks for Regalium Crystal and the Undergarden ingots and crystals.[4]
In the basic tools chapter, Undergarden gear is one option among several mods. For example, a quest in "?" accepts a Froststeel or Cloggrum pickaxe, and a quest in "?" accepts a Forgotten or Cloggrum sword. So a trip underground can knock out several of those quests at once.[5]
How do you get started with The Undergarden?
4 parts
The Undergarden is a dark world deep below the bedrock of the Overworld. Its plants grow without light, and it is overrun by hostile monsters called Rotspawn. Your first job is getting there, and that starts with one item: the Catalyst. The Undergarden quest chapter has a quest for it, a quest in "?".[1][2]
Step 1: Craft the Catalyst and open the portal
This pack changed the Catalyst recipe, so don't follow the mod's default recipe from outside guides. Use the in-pack version below.[6]

Recipe changed by this pack
- Build a frame shaped like a Nether portal out of Stone Bricks or Deepslate Bricks. Bricks made from Undergarden stone also work.[1]
- Right-click the inner bottom of the frame with the Catalyst to light the portal.[1]
Step 2: Cloggrum, your first metal
Once you're through, mine your first Undergarden ore. The Cloggrum Ingot quest, a quest in "?", leads to the quests for the tools, the armor, and the battleaxe and shield. In this pack, the smelting and blasting recipes for cloggrum ore and raw cloggrum are changed, so they accept any item with the matching cloggrum tag.[2][6][7]
Smelting
- any cloggrum raw material
Recipe id: undergarden:smelt_raw_cloggrum
Recipe changed by this pack
Make the Cloggrum tools first for the a quest in "?" quest. The pack changed their recipes too, so check the in-pack versions below. Keep your Cloggrum tools and weapons, because they are the base for the later Forgotten upgrades.[2][6][7]

Next, make the full Cloggrum armor set for a quest in "?". Cloggrum Boots are worth wearing early, because Scintling Goo won't slow you down while you have them on.[2][7]

Recipe id: undergarden:cloggrum_helmet
The pack also adds its own recipe for the Cloggrum Shield, which counts for a quest in "?". You can't craft the Cloggrum Battleaxe from that quest. You get it from a Forgotten that is carrying one.[2][6][7]

Step 3: A Slingshot and some bombs
The Slingshot gives you a ranged option early on, and it has its own quest, a quest in "?". It fires pebbles, and you can also load it with Rotten Blisterberries and Gronglets. This pack adds a second way to make it: cut Wigglewood logs or wood in a sawmill.[2][6][7]

Where to go next
- Utherium: collect Utherium Crystal for a quest in "?", which leads to the Utherium tools and armor. Utherium weapons deal 1.5x damage to Rotspawn.[2][7]
- Froststeel: the Froststeel Ingot quest, a quest in "?", leads to a Froststeel tool quest and a Froststeel armor quest.[2]
- Forgotten metal: forge a Forgotten Ingot from the nuggets a Forgotten Guardian drops. Then use it with a Smithing Template to upgrade your Cloggrum gear. Forgotten tools mine Undergarden blocks 1.5x as fast, and Forgotten weapons deal 1.5x damage to non-boss Undergarden mobs.[6][7]
- Food: the chapter also has a quest for Underbeans, a quest in "?". You pick them from Underbean Bushes.[2][7]
How does The Undergarden work?
5 parts
Same as in the All the Mods 10 8.1 guide
Here's the honest picture first: the sources I have for The Undergarden don't describe any machines, multiblocks, power, fluids or automation. This mod is about a dimension to explore, so its systems are the portal, the gear progression, the slingshot and the status effects. Those are what this section covers.[1][8]
Getting in: the Catalyst and the portal
The Undergarden is a dark world deep below the bedrock of the Overworld. To get in, you first craft a Catalyst. Here's the in-pack recipe:[1][9]
Crafting Shaped
| any gold ingot | any iron ingot | any gold ingot |
| any iron ingot | any diamond gem | any iron ingot |
| any gold ingot | any iron ingot | any gold ingot |
Recipe id: undergarden:catalyst
Next, build a frame in the shape of a Nether portal out of Stone Bricks or Deepslate Bricks. Bricks derived from the Undergarden work too. Then right-click the inner bottom of the frame with the Catalyst to activate the portal.[1]
Cloggrum and Forgotten gear
The pack has changed a lot of the Cloggrum recipes: the axe, hoe, bars, block, block-to-ingot, ingot-to-nugget, helmet, chestplate, boots and lantern all show up as changed by the pack. The Cloggrum Bucket is the exception and stays as the mod made it. The sources don't say exactly what changed, so check the recipe viewer for the real in-pack versions.[9]
Crafting Shaped
4 × any cloggrum ingot
Recipe id: undergarden:cloggrum_boots
This recipe is changed by the pack. The boots also stop Scintling Goo from slowing you down while worn.
The next step up is Forgotten gear. You forge a Forgotten Ingot from a Forgotten Guardian's nuggets, then use it to upgrade Cloggrum tools and weapons. The smithing template slot takes a Cloggrum weapon or tool. There are 6 Forgotten tools to collect in total.[8]
- Forgotten tools mine Undergarden blocks 1.5x as fast.[8]
- Forgotten weapons deal 1.5x damage to non-boss Undergarden mobs.[8]
- Utherium weapons deal 1.5x damage to Rotspawn.[8]
The Slingshot
The Slingshot fires pebbles, and items with the Slingshot ammo tooltip can be loaded into it. The advancements mention Scintling Goo Balls, Gronglets and Rotten Blisterberries as things you can shoot. These enchantments are specific to it:[8]
- Longevity increases the Slingshot's max durability.[8]
- Ricochet makes projectiles bounce off block surfaces.[8]
- Self Sling makes the Slingshot fire you instead of ammo, and you have to be on the ground.[8]
Explosives from the gourd patch
The pack has recipes for the Blisterbomb and the Boomgourd, which builds on the Blisterbomb. Here are both in-pack recipes:[9]

Rotspawn, infection and status effects
The Undergarden is plagued by Rotspawn, monsters that come from a chaotic, mysterious realm. You can also contract the Utheric Infection, and the game warns you not to let it get out of control. A Shard Torch damages Rotspawn near it.[1][8]
- Purity reduces the amount of Utheric Infection an entity has per second, and the amount removed scales with potion level.[8]
- Virulence is similar to poison but does more damage at a slower rate. Virulent Resistance suppresses it and grants immunity.[8]
- Brittleness makes the victim take more damage the higher their armor value is, scaling with potion level.[8]
- Chilly slows the victim down and makes them visually shake.[8]
- Featherweight gives a damaged victim increased knockback, scaling with potion level.[8]
- Gooey constantly places Scintling Goo under the victim's feet.[8]
How do you progress through The Undergarden?
7 parts
The Undergarden has its own quest chapter in this pack, and it's the best map of the mod's gear tiers. Each material gets a quest for its base item: Cloggrum, Froststeel, Utherium, Forgotten metal and Regalium. Finishing a material's quest unlocks follow-up quests for that material's tool set and armor set.[2]
The Catalyst
The chapter includes a quest for the Catalyst, a quest in "?". This pack changed the Catalyst recipe to use common tags, so any diamond, gold ingot and iron ingot that share those tags will work.[2][6]
Crafting Shaped
| any gold ingot | any iron ingot | any gold ingot |

Pack-modified recipe
Unverified What the Catalyst does, and whether it gates the rest of the chapter, isn't covered by the quest data here.
Cloggrum
Cloggrum is your first real metal. Grab a Cloggrum Ingot for a quest in "?" by smelting or blasting Cloggrum ore or raw Cloggrum. That quest unlocks a quest in "?" for the full tool set, a quest in "?" for the armor, and a quest in "?" for the Cloggrum Battleaxe and Cloggrum Shield.[2][6]
This pack changed the Cloggrum tool, armor and storage block recipes to accept any item tagged as a Cloggrum ingot. The pack also added its own recipe for the Cloggrum Shield.[6]

Froststeel
a quest in "?" asks for a Froststeel Ingot. You can smelt or blast Raw Froststeel or Shiverstone Froststeel Ore to get one. From there, a quest in "?" covers the tools and a quest in "?" covers the armor. These use the mod's standard recipes.[2][6]

Recipe id: undergarden:froststeel_pickaxe
Utherium
a quest in "?" needs a Utherium Crystal. You can get one by smelting or blasting Utherium items, or by converting a Utheric Cluster with the Undergarden's infuser conversion. This quest unlocks a quest in "?" for tools and a quest in "?" for armor.[2][6]
This pack changed the Utherium tool, armor and block recipes to use the common Utherium gem tag instead of the mod's own item.[6]
Crafting Shaped
| any utherium gem |

Recipe id: undergarden:utherium_sword
Forgotten metal
a quest in "?" asks for a Forgotten Ingot, and you can also craft one from Forgotten Nugget. It unlocks a quest in "?" for tools and a quest in "?" for the Forgotten Battleaxe. Forgotten gear isn't crafted from scratch. Instead, you upgrade Cloggrum gear in a smithing table with a Forgotten Ingot and a Smithing Template.[2][6]
Unverified Where Forgotten Ingots and the upgrade Smithing Template are found isn't covered by these sources.
Regalium and Ancient armor
a quest in "?" asks for a Regalium Crystal. You get it by smelting or blasting Regalium ore, and this pack changed those recipes to accept any tagged Regalium ore. If you run Productive Bees, a centrifuge recipe also produces Regalium Crystals.[2][6]
The chapter also has a quest in "?", which asks for the Ancient Helmet, Ancient Chestplate and Ancient Leggings.[2]
Unverified How to obtain the Ancient armor isn't covered by these sources.
Other chapters
The Undergarden's materials also appear in the pack's general chapters. The basic armor chapter repeats the ingot, crystal and armor-set quests for Cloggrum, Froststeel, Utherium, Forgotten metal and Regalium.[4]
- a quest in "?" accepts a Froststeel or Cloggrum pickaxe, among pickaxes from other mods.[5]
- a quest in "?" accepts a Utherium pickaxe as one of its options.[5]
- a quest in "?" accepts a Forgotten pickaxe or a Warden pickaxe.[5]
- a quest in "?" accepts a Forgotten or Cloggrum sword, a quest in "?" accepts a Froststeel sword, and a quest in "?" asks for a Utherium sword.[5]
- The building tips chapter has a quest in "?", which accepts any of the Undergarden storage blocks.[10]
Unverified The sources don't give stats or mining levels, so the exact power order of these tiers can't be confirmed here.
How does The Undergarden work with other mods?
3 parts
The Undergarden's links to the rest of this pack come in three flavours: the pack adds sawing recipes for its woods, BiblioCraft furniture comes in Undergarden wood types, and several quest chapters outside the Undergarden chapter use its metals, tools and armor. Here's what connects to what.[4][5][6][10]
Sawing Undergarden wood
The pack adds Mekanism sawing recipes for all four Undergarden woods. They turn Ancient Root and the Grongle, Smogstem and Wigglewood logs into Ancient Root Planks, Grongle Planks, Smogstem Planks and Wigglewood Planks. Each recipe also gives you Mekanism's Sawdust as a second output.[6]
Sawing (mekanism)
- any grongle log
Recipe id: allthemods:mekanism/sawing/undergarden/grongle_planks
The Ancient Root, Smogstem and Wigglewood versions work the same way.
The pack also adds Productive Trees sawmill recipes that produce the same four plank types. These recipes involve Productive Trees' own Sawdust, so check the recipe view to see exactly how they are set up.[6]
Sawmill (productivetrees)
2× Sawdust
- any wigglewood log
Recipe id: allthemods:productivetrees/sawing/undergarden/wigglewood_planks
BiblioCraft furniture
If you like decorating, Grongle, Smogstem and Wigglewood slabs are used in BiblioCraft furniture recipes. These are the mod's own recipes, not pack additions. You can make display cases, seats and several seat backs: small, flat, raised, tall and fancy. They come in colored variants, including black, blue and brown, such as the Blue Smogstem Display Case or the Brown Grongle Seat.[6]

Quests in other chapters
The Undergarden has its own quest chapter, but its gear also appears in the pack's general chapters. In the basic armor chapter, quests ask for the Cloggrum Ingot, Froststeel Ingot, Forgotten Ingot, Utherium Crystal and Regalium Crystal. Other quests in that chapter ask for the full Cloggrum, Froststeel and Utherium armor sets.[4]
The basic tools chapter is where Undergarden gear competes with other mods. Several quests accept any one of a group of tools, so an Undergarden tool can stand in for one from Deeper Darker, Eternal Starlight or Aquaculture.[5]
- a quest in "?" accepts the Utherium Pickaxe or a pickaxe from Eternal Starlight, Aquaculture or Deeper Darker.[5]
- a quest in "?" accepts the Froststeel Pickaxe, the Cloggrum Pickaxe or one of two Eternal Starlight pickaxes.[5]
- a quest in "?" accepts the Forgotten Sword, the Cloggrum Sword or a Deeper Darker sword.[5]
- a quest in "?" accepts the Froststeel Sword or one of several Eternal Starlight swords.[5]
- a quest in "?" accepts the Forgotten Pickaxe or a Deeper Darker pickaxe.[5]
- a quest in "?" wants the Utherium Sword specifically.[5]
In the building tips chapter, a quest in "?" accepts any one of the Undergarden metal blocks, including the Block of Cloggrum, Block of Froststeel and Block of Utherium. A single storage block is enough to tick it off.[10]
Which All the Mods 10 quests use The Undergarden?
3 parts
The Undergarden has its own quest chapter in this pack, and its items also appear in the armor, tools and building chapters. Most of these quests are simple collection tasks: grab the item, tick the quest. Here's what each chapter asks for and how the quests unlock.[2][4][5][10]
The Undergarden chapter
The chapter starts with a quest in "?", which asks for a Catalyst and has no prerequisite. Almost every other quest here unlocks after the same earlier quest, so once that's done you can work through the chapter in any order you like.[2]
A big part of the chapter is exploring and gathering. Each of these quests asks for a single item you'll pick up while wandering the dimension:[2]
- Food and plants: Underbeans for a quest in "?", Blisterberry for a quest in "?", Droopfruit for a quest in "?", Glitterkelp for a quest in "?" and Gloomgourd for a quest in "?".[2]
- Mushrooms: Veiled Mushroom for a quest in "?", Indigo Mushroom for a quest in "?", Blood Mushroom for a quest in "?" and Ink Mushroom for a quest in "?".[2]
- Saplings: Grongle Sapling for a quest in "?", Wigglewood Sapling for a quest in "?" and Smogstem Sapling for a quest in "?".[2]
- Gadgets and combat: a Slingshot for a quest in "?", a Gronglet for a quest in "?", and both a Blisterbomb and a Boomgourd for a quest in "?".[2]
Metals and gear
The materials quests are where the chapter branches out. Getting the base material unlocks follow-up quests for the gear made from it, so collect the ingot or crystal first.[2]
- Cloggrum: a quest in "?" asks for a Cloggrum Ingot and unlocks a quest in "?" (full Cloggrum armor), a quest in "?" (pickaxe, axe, shovel, hoe and sword) and a quest in "?" (Cloggrum Battleaxe and Cloggrum Shield).[2]
- Froststeel: a quest in "?" asks for a Froststeel Ingot and unlocks a quest in "?" (full Froststeel armor) and a quest in "?" (the Froststeel tool set and sword).[2]
- Utherium: a quest in "?" asks for a Utherium Crystal and unlocks a quest in "?" (full Utherium armor) and a quest in "?" (the Utherium tool set and sword).[2]
- Forgotten metal: a quest in "?" asks for a Forgotten Ingot and unlocks a quest in "?" (the Forgotten tool set and sword) and a quest in "?" (Forgotten Battleaxe).[2]
- Regalium: a quest in "?" just asks for a Regalium Crystal.[2]
There's also a quest in "?", which wants the Ancient Helmet, Ancient Chestplate and Ancient Leggings. This one needs two earlier quests completed before it opens up, so expect it later than the rest.[2]
Other chapters
The basic_armor chapter repeats the Undergarden materials and armor sets as standalone quests: a quest in "?" for a Cloggrum Ingot, a quest in "?" for a Froststeel Ingot, a quest in "?" for a Utherium Crystal, a quest in "?" for a Forgotten Ingot and a quest in "?" for a Regalium Crystal. Full armor sets are covered by a quest in "?" (Cloggrum), a quest in "?" (Froststeel) and a quest in "?" (Utherium).[4]
In the basic_tools chapter, several quests accept Undergarden gear as one of a few options, so it's a handy shortcut if you're already kitted out. a quest in "?" takes a Froststeel or Cloggrum pickaxe, a quest in "?" takes a Utherium pickaxe, a quest in "?" takes a Forgotten pickaxe, a quest in "?" takes a Forgotten or Cloggrum sword and a quest in "?" takes a Froststeel sword. a quest in "?" specifically wants the Utherium Sword.[5]
Finally, the building_tips chapter has a quest in "?", which accepts any one of the metal blocks: Block of Cloggrum, Block of Regalium, Block of Froststeel, Block of Forgotten Metal or Block of Utherium.[10]
Unverified The shared quest that unlocks most of the Undergarden chapter isn't identified in the quest data available here, so it's not confirmed whether it's the Catalyst quest or something else.
What changed in The Undergarden between versions?
The sources I have only cover a few pack releases, so this is a short history. The Undergarden has been part of All the Mods 10 since version 2.2 or earlier, and All the Mods 10 4.5 ships version 0.9.3 of the mod.[3]
- All the Mods 10 4.0: The Undergarden was updated from 0.8.22 to 0.9.1.[11]
- All the Mods 10 4.1: The Undergarden was updated from 0.9.1 to 0.9.3.[12]
- All the Mods 10 4.5: still on 0.9.3, so there has been no Undergarden update since 4.1 in the sources I have.[3][12]
Unverified What actually changed inside the mod between 0.8.22, 0.9.1 and 0.9.3 is unverified. The pack changelogs only list the version numbers, and there are no stored changelogs for the shipped jars, so I can't tell you about new content, fixes or balance changes.
