What is The Undergarden?
2 parts
The Undergarden adds a dark, subterranean dimension that sits deep below the bedrock of the Overworld. The plants down there have adapted to life without sunlight and grow anywhere regardless of light level, and the place is home to strange creatures alongside the invasive Rotspawn, monsters that come from a chaotic, mysterious realm.[1]
It is built as an exploration dimension first: a whole new world to explore, build and survive in, with 15 biomes, over 10 unique entities, over 10 music tracks, 4 special potion effects and 1 dungeon. There are also over 10 advancements to point you in the right direction as you poke around.[1]
The part most players come for is the ores. Undergarden ores have special properties when you turn them into tools and weapons, so a trip down there is an easy way to upgrade your gear early on without touching heavier tech mods.[1]
Getting in
Entry works a bit like the Nether. You craft a Catalyst, build a Nether-portal-shaped frame out of Stone Bricks or Deepslate Bricks, then right-click the inner bottom of the frame with the Catalyst to light it. Bricks derived from the Undergarden itself also work for the frame.[1]
Where it fits in this pack
This pack leans on the Undergarden for its early gear progression. The basic armor quest chapter asks you for Cloggrum Ingot, Froststeel Ingot, Forgotten Ingot, Utherium Crystal and Regalium Crystal, plus full sets of Cloggrum, Froststeel and Utherium armor.[2]
The basic tools chapter accepts Undergarden gear for most of its steps, usually as one option among several mods. A Froststeel Pickaxe or Cloggrum Pickaxe satisfies a quest in "?", the Forgotten Pickaxe covers a quest in "?", and the Utherium Pickaxe works for a quest in "?". On the weapon side, a quest in "?" specifically wants the Utherium Sword, while the Forgotten Sword, Cloggrum Sword and Froststeel Sword each count toward other sword quests.[3]
This pack ships The Undergarden 0.8.22, and the mod is not part of the ATM Star quest path, so treat it as an optional but very convenient gearing detour.[4]
How do you get started with The Undergarden?
5 parts
The Undergarden is a dark, subterranean dimension that sits deep below the Overworld's bedrock, with its own plants, its own mobs and ores that give tools and weapons special properties. Your first job is simply getting there, and then getting a full kit of Undergarden metal so the place stops being dangerous.[1]
Step 1: Get into the dimension
Entry starts with a Catalyst. Once you have one, build a frame the same shape as a Nether portal out of Stone Bricks or Deepslate Bricks, then right-click the inner bottom of the frame with the Catalyst to light it. Bricks made from Undergarden stone work for the frame too, which is handy once you want a return portal on the other side.[1]
Unverified The exact Catalyst recipe used in this pack isn't confirmed by the sources here, so check it in JEI/EMI before you go shopping for ingredients. This site does hold All the Mods 10's own recipes, read from the pack itself: look the item up in the item browser.
Step 2: Smelt Cloggrum
Cloggrum is the starter metal. You'll find Cloggrum ore in both of the dimension's main stones, Depthrock and Shiverstone, and mining it drops Raw Cloggrum that cooks down into Cloggrum Ingots in a furnace or, faster, a blast furnace. Grab a quest in "?" on the way, since it just asks for a Cloggrum Ingot.[2][5]
A blasting version, undergarden:blast_raw_cloggrum, is also available.
The pack also adds Ender IO alloy smelting recipes for the Undergarden ores, so once you have an Alloy Smelter running you can feed it raw ore or the ore blocks directly instead of using a furnace.[5]

Recipe id: enderio:smelting/undergarden/smelt_raw_cloggrum
Step 3: Cloggrum pickaxe, sword and armor
Make the pickaxe and sword before anything else: the pickaxe gets you through the rest of the ores, and the sword is accepted by a quest in "?".[3][5]

Step 4: Froststeel and Utherium
- Froststeel ore shows up in Shiverstone and drops Raw Froststeel, which smelts or blasts into Froststeel Ingot for a quest in "?"; from there you can make the pickaxe, sword and a full armor set for a quest in "?".[2][5]
- Utherium ore in Depthrock and Shiverstone cooks straight into Utherium Crystal for a quest in "?", and Utheric Shards can be crafted up into crystals as well. Utherium weapons deal 1.5x damage to Rotspawn, which is exactly what you want down there.[2][5][6]
- Regalium Crystal comes from Regalium ore in either stone, and completes a quest in "?". If you're running Productive Bees, a centrifuge can also pull Regalium Crystals out of the right honeycomb.[2][5]

Step 5: Upgrade to Forgotten gear
Forgotten Ingots are forged from the nuggets a Forgotten Guardian drops, and they complete a quest in "?". You don't craft Forgotten tools from scratch: you upgrade Cloggrum ones at a smithing table using Smithing Template, which only accepts a Cloggrum weapon or tool in the base slot. That's the payoff for making Cloggrum gear first.[2][5][6]
How does The Undergarden work?
6 parts
Same as in the All the Mods 10 2.6 guide
The Undergarden is a dimension mod rather than a tech mod: there are no machines, no power network and no fluid or item pipes to wire up here. Its systems are a new world to explore, the ores and gear you bring out of it, and a handful of status effects that change how fights play out. The feature list is a whole dimension, over 10 unique entities, 15 biomes, ores with special properties when made into tools and weapons, over 10 music tracks, over 10 advancements, 4 special potion effects and 1 dungeon.[1]
Getting there: the Catalyst and the portal
Everything starts with the Catalyst. In this pack the Catalyst recipe has been changed from the mod default, so check the panel below rather than going from memory or an old video.[1][7]

Changed by the pack
- Craft the Catalyst.[1][7]
- Build a frame in the shape of a Nether portal out of Stone Bricks or Deepslate Bricks.[1]
- Right click the inner bottom of the frame with the Catalyst to light it.[1]
The Undergarden itself sits deep underground, below the bedrock of the Overworld. Its plants have adapted to grow anywhere without light, and the native creatures share the place with the invasive Rotspawn, monsters that come from a separate chaotic realm.[1]
Ores and the gear progression
The core progression loop is ore to gear to better gear. Undergarden ores have special properties once you turn them into tools and weapons, so the metal you pick matters more than a raw stat line would suggest.[1]
Cloggrum is the entry metal and covers the full kit: sword, axe, pickaxe, shovel, hoe, shield, the four armour pieces and decorative blocks. Cloggrum Boots carry their own perk, since Scintling Goo does not slow you down while you are wearing them.[6][7]

Recipe id: undergarden:cloggrum_pickaxe
Cloggrum storage works the way you would expect from a vanilla metal, with recipes both ways between Cloggrum Nugget, Cloggrum Ingot and Block of Cloggrum, so nothing you smelt is ever stuck in the wrong form.[7]
The next tier is Forgotten gear, and it is a smithing upgrade rather than a fresh craft. The Forgotten upgrade template takes a cloggrum weapon or tool in its base slot, and Forgotten Ingots are forged from the nuggets dropped by Forgotten Guardians. Working through it unlocks all 6 Forgotten tools.[6]
The special properties show up as tooltips on the finished gear. Forgotten tools mine Undergarden blocks 1.5x as fast, Forgotten weapons deal 1.5x damage to non-boss Undergarden mobs, and Utherium weapons deal 1.5x damage to Rotspawn. There is also a Cloggrum Battleaxe, which you get from a Forgotten that is carrying one, and it can be upgraded with a Forgotten Ingot like the rest.[6]
Status effects
The mod adds its own effects, and several of them are things monsters and traps will put on you rather than buffs you brew.[1][6]
- Brittleness: the higher the victim's armour value, the more damage they take, and the damage scales with the potion level. Heavy armour is a liability here.[6]
- Virulence: similar to poison, but does more damage at a slower rate.[6]
- Virulent Resistance: grants immunity to Virulence and suppresses its damage.[6]
- Featherweight: the victim receives increased knockback when damaged, scaling with the potion level.[6]
- Chilly: slows the victim down and makes them visually shake.[6]
- Gooey: Scintling Goo is constantly placed under the victim's feet.[6]
The Slingshot
The Slingshot is the mod's ranged system and it runs on ammo you pick up around the dimension. Anything usable in it is labelled as Slingshot ammo on the item tooltip, so you can tell at a glance what is worth carrying. Pebbles are the basic shot, but you can also load Scintling Goo Balls to annoy a target, Rotten Blisterberries, and even a Gronglet.[6]
It has three enchantments of its own. Longevity increases the Slingshot's max durability, Ricochet makes fired projectiles bounce off block surfaces, and Self Sling fires you instead of your ammo, which requires you to be standing on the ground.[6]
Other systems worth knowing
- Stoneborn will trade with you, so they are your in-dimension shop.[6]
- The Shard Torch is a torch that damages Rotspawn in its vicinity, which makes it a defensive block as much as a light source.[6]
- You can create a Forgotten Minion using a Forgotten Block and a Carved Gloomgourd, the same way you would build a golem.[6]
- Gloomgourds grow from seeds you plant, so they are a renewable farm crop.[6]
- Gwiblings are caught with a bucket rather than fought.[6]
- The Catacombs are the dimension's dungeon, and the Forgotten Guardian you need for Forgotten Ingots is the fight that gates the upgrade tier.[1][6]
Crafting odds and ends
Beyond gear, the pack's recipe set covers a full decorative and utility line: brick slabs and stairs, chiseled variants of depthrock, shiverstone and tremblecrust bricks made from their slabs, cloggrum tiles, bars and a lantern, a mogmoss rug, and a depthrock bed. Deepsoil converts both ways between its normal and coarse forms, just like dirt.[7]
Two combat consumables chain into each other: the Blisterbomb is built from Rotten Blisterberry and Twistytwig, and feeding a Blisterbomb into a Gloomgourd gives you a Boomgourd.[7]

How do you progress through The Undergarden?
4 parts
The Undergarden's gear progression in this pack is built around metal tiers, and the pack's quests track each one. They are split between an armor chapter and a tools chapter. The metals you'll meet are Cloggrum, Froststeel, Utherium, Regalium and the Forgotten metal.[2][3]
Getting the materials
Cloggrum and Froststeel both end up as ingots. You can get Cloggrum Ingot from Raw Cloggrum or from the Depthrock and Shiverstone cloggrum ores. You can get Froststeel Ingot from Raw Froststeel or from Shiverstone Froststeel Ore. All of these smelt in a regular furnace, and the mod also gives them blasting recipes.[5]
Utherium and Regalium end up as crystals. Depthrock Utherium Ore and Shiverstone Utherium Ore give you Utherium Crystal. Depthrock Regalium Ore and Shiverstone Regalium Ore give you Regalium Crystal. A Utheric Shard can also be turned into a Utherium Crystal, as shown below.[5]
This pack adds extra Ender IO alloy smelting recipes for the same ore-to-ingot and ore-to-crystal conversions, so you aren't limited to a vanilla furnace if you already have Ender IO machines running. The mod's own furnace and blasting recipes still exist alongside them.[5]
There is also a Productive Bees centrifuge recipe that outputs a Regalium Crystal along with wax, which gives you a non-mining route to that material.[5]

Recipe id: productivebees:centrifuge/undergarden/honeycomb_regalium
Armor quests
The armor chapter asks for each metal as a material first and then as a full set. Each of these quests is satisfied by owning the items.[2]
- Cloggrum: first a quest in "?" asks for a Cloggrum Ingot. Then a quest in "?" asks for the full set: Cloggrum Helmet, Cloggrum Chestplate, Cloggrum Leggings and Cloggrum Boots.[2]
- Froststeel: a quest in "?" asks for a Froststeel Ingot, then a quest in "?" asks for the Froststeel helmet, chestplate, leggings and boots.[2]
- Utherium: a quest in "?" asks for a Utherium Crystal, then a quest in "?" asks for the Utherium helmet, chestplate, leggings and boots.[2]
- Regalium and Forgotten: a quest in "?" asks for a Regalium Crystal and a quest in "?" asks for a Forgotten Ingot. The armor chapter has no set quest for either of these.[2]
The sources don't say in what order the armor quests unlock, so you can plan your own route through them.[2]
Tool quests
The tools chapter is more flexible. Several quests accept a pickaxe or sword from this mod or from other mods.[3]
- a quest in "?" accepts a Froststeel Pickaxe or a Cloggrum Pickaxe, or a pickaxe from Eternal Starlight.[3]
- a quest in "?" accepts a Utherium Pickaxe, or a pickaxe from Eternal Starlight, Aquaculture or Deeper and Darker.[3]
- a quest in "?" accepts a Forgotten Pickaxe or a Deeper and Darker Warden Pickaxe.[3]
- a quest in "?" accepts a Forgotten Sword or a Cloggrum Sword, or a Deeper and Darker Resonarium Sword.[3]
- a quest in "?" accepts a Froststeel Sword or one of several Eternal Starlight swords.[3]
- a quest in "?" specifically asks for a Utherium Sword.[3]
Crafting the tool tiers
The Cloggrum, Froststeel and Utherium pickaxes are all crafted at a crafting table. Here are the in-pack recipes.[5]

How does The Undergarden work with other mods?
3 parts
In this pack the Undergarden connects to other mods through wood processing, through bee recipes that produce its materials, and through quests that accept its tools alongside gear from other mods.[3][5]
Sawing Undergarden logs
The pack adds sawing recipes for Grongle, Smogstem and Wigglewood logs in Mekanism and in Productive Trees. In Mekanism, sawing any of these logs gives you planks and also Sawdust. In the Productive Trees sawmill, you put in Sawdust together with the logs to get the planks. The pack added all of these recipes, they are not the mods' own.[5]

Smogstem Planks and Wigglewood Planks have matching recipes in both machines. Their recipe ids follow the same pattern as the Grongle ones above.[5]
Productive Bees
Productive Bees has centrifuge recipes whose results are Wax plus an Undergarden material. The cloggrum one gives Raw Cloggrum, the forgotten one gives Forgotten Nugget and the froststeel one gives Raw Froststeel. The regalium one gives Regalium Crystal and the utheric one gives Utheric Shard. These are the mod's own recipes, not pack changes.[5]
Centrifuge (productivebees)
Recipe id: productivebees:centrifuge/undergarden/honeycomb_cloggrum
There is also a bee conversion recipe that uses the Undergarden's Music Disc to get the regalium bee. It is also a mod recipe, not a pack change.[5]

Recipe id: productivebees:bee_conversion/undergarden/regalium_bee
Shared tool quests
Several quests in the basic tools chapter accept Undergarden gear or gear from another mod. For example, a quest in "?" takes the Utherium Pickaxe or a pickaxe from Eternal Starlight, Aquaculture or Deeper Darker. a quest in "?" takes the Froststeel Pickaxe or Cloggrum Pickaxe, or an Eternal Starlight pickaxe.[3]
The sword and pickaxe quests work the same way. a quest in "?" accepts the Forgotten Sword or Cloggrum Sword, or a Deeper Darker sword. a quest in "?" accepts the Froststeel Sword or one of several Eternal Starlight swords. a quest in "?" accepts the Forgotten Pickaxe or a Deeper Darker pickaxe.[3]
Which All the Mods 10 quests use The Undergarden?
2 parts
The Undergarden shows up in two quest chapters in this pack: basic_armor and basic_tools. Both are about turning the dimension's metals into gear. None of these quests has a title in the quest files, so I describe each one by what it asks for.[2][3]
Chapter: basic_armor
This chapter is all Undergarden. It pairs materials with armor sets, and the quest files don't show any prerequisites between these quests. That means I can't tell you a fixed order, so work through them in whatever order suits your progress.[2]
- a quest in "?" asks you to obtain a Froststeel Ingot.[2]
- a quest in "?" asks for the full Froststeel set: Froststeel Helmet, Froststeel Chestplate, Froststeel Leggings and Froststeel Boots.[2]
- a quest in "?" asks you to obtain a Cloggrum Ingot.[2]
- a quest in "?" asks for the full Cloggrum set: Cloggrum Helmet, Cloggrum Chestplate, Cloggrum Leggings and Cloggrum Boots.[2]
- a quest in "?" asks you to obtain a Utherium Crystal.[2]
- a quest in "?" asks for the full Utherium set: Utherium Helmet, Utherium Chestplate, Utherium Leggings and Utherium Boots.[2]
- a quest in "?" asks you to obtain a Regalium Crystal.[2]
- a quest in "?" asks you to obtain a Forgotten Ingot.[2]
Chapter: basic_tools
Here Undergarden shares the chapter with other mods. Most of these quests accept any one item from a list, so an Undergarden tool is just one of several ways to finish them. All six quests below unlock after the same earlier quest, so they open up together and you can do them in any order.[3]
- a quest in "?" accepts a pickaxe from one of several mods. The Undergarden option is the Utherium Pickaxe.[3]
- a quest in "?" accepts either the Froststeel Pickaxe or the Cloggrum Pickaxe. Pickaxes from another mod also count.[3]
- a quest in "?" accepts either the Forgotten Sword or the Cloggrum Sword. A sword from another mod also counts.[3]
- a quest in "?" accepts the Froststeel Sword, or swords from another mod.[3]
- a quest in "?" is the only quest here that asks for one specific Undergarden item: the Utherium Sword.[3]
- a quest in "?" accepts the Forgotten Pickaxe, or a pickaxe from another mod.[3]
Which The Undergarden config options matter?
Same as in the All the Mods 10 2.6 guide
Unverified This pack doesn't ship a config file for The Undergarden, so there are no pack-specific values to tune here: nothing has been changed from the mod's own defaults, and there's no file to edit in the pack's config folder.
That means the dimension behaves as the mod ships it: the biomes, mobs, ores and dungeon are all there with no pack-side adjustments you need to know about before you dive in.[1]
What changed in The Undergarden between versions?
2 parts
All the Mods 10 1.15 ships The Undergarden 0.8.22. The mod has been in the pack since All the Mods 10 0.42 or earlier. The notes below come from the mod's own changelogs for its two most recent versions, since I have no pack changelog entries for this mod.[4]
0.8.22 (the version in 1.15)
- Forgotten are now considered undead.[8]
- A special dimension transition screen was added for the Undergarden.[8]
- Undergarden food items were added to the c:foods tag.[8]
- Underbeans, Blisterberries and Ditchbulbs were not growing, and that is now fixed.[8]
0.8.21
- Fixed the Undergarden portal effect messing with other portals.[9]
If you were having trouble getting those three crops to grow on an older pack version, the 0.8.22 fix is the reason it works now.[4][8]
