Sophisticated Backpacks in All the Mons

Sophisticated Backpacks adds upgradable backpacks that can use filters to add nifty features. You can wear a backpack in your Curios Back slot, and you can dye it. This pack includes version 3.26.1 of the mod, and everything here is about that version.^[1][2]

Where it sits in the quest book

The pack's quest book puts the mod in the chapter "Basic Storage", in the "Storage" group. It is chapter 30 of 70 in the book and has 89 quests. The chapter intro says you'll find all of the basic ways to store items without needing power. The entry quest is "Sophisticated Backpacks" quest, and it asks you for a Backpack. In the chapter it is listed right after the "Sophisticated Storage" quest quest, and the sources show no prerequisite for it.^[2]

Everything else in the mod branches off from that quest:^[2]

• The backpack tiers form a chain: "Copper Backpack" quest, then "Iron Backpack" quest, "Gold Backpack" quest, "Diamond Backpack" quest and finally "Netherite Backpack" quest.^[2]
• a quest in "Basic Storage" also follows the main backpack quest. The quest book says you will need these to make backpack upgrades, and the individual upgrade quests come after it.^[2]
• The advanced upgrades follow their basic versions. For example, "Advanced Filter Upgrade" quest comes after a quest in "Basic Storage".^[2]
• The stack upgrades run from "Stack Upgrade Tier 1" quest through "Stack Upgrade Tier 2" quest and "Stack Upgrade Tier 3" quest to "Stack Upgrade Tier 4" quest. The quest book says they increase stack size in the backpack by 2, 4, 8 and 16.^[2]
• "Experience Pump Upgrade" quest comes after "Advanced Pump Upgrade" quest.^[2]

The chapter has more quests than the ones covered here. The rest are in the quest book, so check there for the full list.^[2]

Welcome to Sophisticated Backpacks! In this pack the whole mod is laid out in the Basic Storage quest chapter, and it starts with the quest "Sophisticated Backpacks" quest. Here is the order I'd go in.^[2]

Make your first backpack

Start with the plain Backpack. It's the first quest in the chapter, and the Copper Backpack and Upgrade Base quests both come after it. The pack changes this recipe from the mod's default, so use the one below.^[2][3]

Recipe id: sophisticatedbackpacks:backpack

Once you have it, you can wear it in your Curios Back slot, and you can dye it. The quest describes these as upgradable backpacks that can use filters to add nifty features.^[2]

Get the Upgrade Base

Next, grab the Upgrade Base. The quest says you need it to make backpack upgrades, and many of the upgrade recipes in the pack use it, so you'll want a few.^[2][3]

Pick your first upgrades

With an Upgrade Base in hand, these are good early picks. Each one has its own quest in the chapter.^[2]

• Crafting Upgrade adds a Crafting Table screen to the backpack.^[2]
• Deposit Upgrade lets you Shift-Right Click an inventory to empty your backpack into it.^[2]
• Filter Upgrade adds a filter for items being pumped in or out of the backpack.^[2]
• Stack Upgrade Tier 1 increases stack size in the backpack by 2. Tiers 2, 3 and 4 raise it by 4, 8 and 16, and the quests follow on from one tier to the next.^[2]

The pack changes these three recipes from the mod's defaults. Here they are as they work in this pack:^[3]

Tier up the backpack itself

The quest chain goes Copper, Iron, Gold, Diamond, then Netherite. The Copper Backpack is the first step, and you make it from your plain backpack.^[2][3]

Sophisticated Backpacks is built around one item with a lot of moving parts: the backpack holds your items, and upgrades in its upgrade slots add behaviour like smelting, magnets, tanks and mob catching. Everything below comes from this pack's server config and recipe list, so these are the values you will actually see in game.^[3][4][5]

Backpack tiers

The tier of the backpack decides how many item slots and how many upgrade slots you get. All of these match the mod's own defaults in this pack, so nothing here has been nerfed or buffed.^[5]

• Leather: 27 inventory slots and 1 upgrade slot (server.leatherBackpack.inventorySlotCount, server.leatherBackpack.upgradeSlotCount).^[5]
• Copper: 45 inventory slots and 1 upgrade slot (server.copperBackpack.inventorySlotCount, server.copperBackpack.upgradeSlotCount).^[5]
• Iron: 54 inventory slots and 2 upgrade slots (server.ironBackpack.inventorySlotCount, server.ironBackpack.upgradeSlotCount).^[5]
• Gold: 81 inventory slots and 3 upgrade slots (server.goldBackpack.inventorySlotCount, server.goldBackpack.upgradeSlotCount).^[5]
• Diamond: 108 inventory slots and 5 upgrade slots (server.diamondBackpack.inventorySlotCount, server.diamondBackpack.upgradeSlotCount).^[5]
• Netherite: 120 inventory slots and 7 upgrade slots (server.netheriteBackpack.inventorySlotCount, server.netheriteBackpack.upgradeSlotCount).^[5]

The pack changes the recipes for the backpack tiers, and they are shown below for the Backpack, the Copper Backpack and the Netherite Backpack. The Diamond Backpack is the tier just below the Netherite one.^[3][5]

Smithing Backpack Upgrade (sophisticatedbackpacks)

This one is a smithing recipe that the pack has changed.

Upgrades and their limits

Upgrades start from an Upgrade Base, and the pack changes that recipe too. The Filter Upgrade is a simple example built on top of it.^[3]

Recipe id: sophisticatedbackpacks:filter_upgrade

The pack limits how many copies of some upgrades a backpack can hold. The limit list allows 3 stack upgrades, 1 from the furnace_upgrades group and 1 from the jukebox_upgrades group per backpack (server.maxUpgradesPerStorage).^[5]

The mod's own messages also say there can only be one Everlasting Upgrade, one Inception Upgrade, one Tool Swapper Upgrade and one Mob Catcher Upgrade per backpack.^[4]

Stack upgrades will not make everything stack. The pack lists items that stay unstackable even with a stack upgrade, including the Immersive Engineering toolbox, the Supplementaries quiver, bundles and every colour of shulker box (server.stackUpgrade.nonStackableItems).^[5]

Filters

Most upgrades use filter slots to decide which items they touch. Here are the filter slot counts in this pack.^[5]

• The Filter Upgrade has 9 filter slots, shown 3 to a row (server.filterUpgrade.filterSlots, server.filterUpgrade.slotsInRow).^[5]
• The Advanced Filter Upgrade has 16 filter slots, shown 4 to a row (server.advancedFilterUpgrade.filterSlots, server.advancedFilterUpgrade.slotsInRow).^[5]
• The Refill Upgrade has 6 filter slots (server.refillUpgrade.filterSlots).^[5]
• The Advanced Refill Upgrade has 12 filter slots (server.advancedRefillUpgrade.filterSlots).^[5]
• The Alchemy Upgrade has 4 filter slots (server.alchemyUpgrade.filterSlots).^[5]
• The Advanced Alchemy Upgrade has 8 filter slots (server.advancedAlchemyUpgrade.filterSlots).^[5]
• The Tool Swapper Upgrade has 8 filter slots (server.toolSwapperUpgrade.filterSlots).^[5]

The void upgrades are set so they can always void, not only on overflow (server.voidUpgrade.voidAlwaysEnabled and server.advancedVoidUpgrade.voidAlwaysEnabled are both true). So be careful what you put in their filters.^[5]

Pickup, magnets and moving items around

The Magnet Upgrade pulls in items within 3 blocks (server.magnetUpgrade.magnetRange).^[5]

The Advanced Magnet Upgrade reaches 5 blocks (server.advancedMagnetUpgrade.magnetRange).^[5]

Deposit and Restock move stacks between the backpack and a nearby inventory, and the game tells you how many stacks moved or that nothing could be moved. If a chest or machine should be left alone, the pack has block lists for that, server.noInteractionBlocks and server.noConnectionBlocks, and both are empty here. Connections to backpacks are also allowed (server.allBlockConnectionsDisallowed is false).^[4][5]

Active upgrades like magnets, pickup, cooking and feeding work in any backpack in your inventory, not only the worn one, because server.nerfs.onlyWornBackpackTriggersUpgrades is false.^[5]

Cooking upgrades

The smelting upgrade has a speed multiplier of 1 (server.smeltingUpgrade.smeltingSpeedMultiplier) and a fuel efficiency multiplier of 1 (server.smeltingUpgrade.fuelEfficiencyMultiplier), which means vanilla furnace speed and fuel use. The smoking, blasting and auto versions are set to the same multipliers in this pack.^[5]

The auto versions also have input and fuel filter slots. The Auto-smelting Upgrade has 8 input filter slots (server.autoSmeltingUpgrade.inputFilterSlots).^[5]

It has 4 fuel filter slots (server.autoSmeltingUpgrade.fuelFilterSlots).^[5]

The pack lets you turn an Auto-smelting Upgrade into an Auto-smoking Upgrade with a recipe instead of crafting from scratch.^[3]

Fluids and energy

The tank upgrade holds 4,000 mB per row of backpack slots (server.tankUpgrade.capacityPerSlotRow).^[5]

Its transfer rate is 20 mB per operation as a base (server.tankUpgrade.maxInputOutput), and that, like the capacity, is multiplied by the number of rows and the stack multiplier.^[5]

Fluid containers in tank slots are filled and drained one bucket's worth at a time, with a cooldown value of 20 between actions (server.tankUpgrade.autoFillDrainContainerCooldown).^[5]

The battery upgrade works the same way for energy: it holds 10,000 FE per row of slots (server.batteryUpgrade.energyPerSlotRow).^[5]

Its base transfer is 20 FE per operation (server.batteryUpgrade.maxInputOutput).^[5]

The pump upgrade has 4 fluid filter slots (server.pumpUpgrade.filterSlots).^[5]

Its base rate is 20 mB per operation (server.pumpUpgrade.maxInputOutput).^[5]

The stack multiplier ratio for the tank (server.tankUpgrade.stackMultiplierRatio), battery (server.batteryUpgrade.stackMultiplierRatio) and pump (server.pumpUpgrade.stackMultiplierRatio) is left at 1 in this pack, so stack upgrades boost them as normal.^[5]

The XP Pump can mend items with Mending (server.xpPumpUpgrade.mendingOn is true), using at most 5 experience points per operation (server.xpPumpUpgrade.maxXpPointsPerMending).^[5]

Mob catcher

Every captured mob takes up a block of empty backpack slots. The basic Mob Catcher Upgrade accepts mobs costing up to 18 slots (server.mobCatcherUpgrade.basicMaxSlotCost).^[4][5]

The Advanced one goes up to 72 slots (server.mobCatcherUpgrade.advancedMaxSlotCost). Both are hard limits, not clamps.^[5]

Hostile mobs have a slot cost multiplier of 2 (server.mobCatcherUpgrade.hostileMultiplier), and animals have a multiplier of 1 (server.mobCatcherUpgrade.animalMultiplier). The game also tells you that hostile mobs need the Advanced upgrade.^[4][5]

Some things can never be captured: bosses, players, mobs with passengers or vehicles, and anything on the entity block list (server.mobCatcherUpgrade.entityBlockList). Only the owner can capture a mob, and you must release captured mobs before removing the upgrade.^[4][5]

The Advanced Mob Catcher Upgrade is an upgrade of the Mob Catcher Upgrade in a recipe the pack changes.^[3]

Backpacks inside backpacks, and the carry limit

The Inception Upgrade lets a backpack work with backpacks stored inside it, and it can only go in a top level backpack. In this pack, upgrades in the contained backpacks stay functional and use the inventories of backpacks inside the backpack (server.inceptionUpgrade.upgradesInContainedBackpacksAreFunctional and server.inceptionUpgrade.upgradesUseInventoriesOfBackpacksInBackpack are both true).^[4][5]

The mod can slow you down if you carry too many backpacks, with the limit set to 3 before slowness would apply (server.nerfs.maxNumberOfBackpacks). The slowness switch is off here (server.nerfs.tooManyBackpacksSlowness is false), so the limit does not slow you down.^[5]

Other players can open your worn backpack by right clicking your back, because server.allowOpeningOtherPlayerBackpacks is true. Each backpack also has a setting to turn this off.^[4][5]

The pack walks you through Sophisticated Backpacks in the Basic Storage quest chapter. You start with a plain backpack, move up through the metal tiers one quest at a time, and then branch into upgrades. Every recipe below is the in-pack version, because the pack changes the recipes for this mod's items.^[2][3]

The backpack tiers

The chain starts with the "Sophisticated Backpacks" quest quest, which asks for a plain Backpack. Its text points out that backpacks can go in your Curios Back slot and can be dyed.^[2]

1. Craft the Backpack to finish the first quest.^[2][3]
2. Upgrade it to the Copper Backpack for "Copper Backpack" quest.^[2][3]
3. Move on to the Iron Backpack. "Iron Backpack" quest needs both the first quest and the Copper Backpack quest done.^[2][3]
4. Next is the Gold Backpack ("Gold Backpack" quest), then the Diamond Backpack ("Diamond Backpack" quest).^[2][3]
5. The last step is the Netherite Backpack ("Netherite Backpack" quest), which follows the Diamond Backpack quest.^[2][3]

This one uses a smithing template, the Diamond Backpack and a netherite ingot, not a plain crafting-grid recipe.

So the iron, gold and diamond steps each take the previous backpack plus one material. The Netherite step also needs the netherite upgrade smithing template.^[3]

Stack upgrades

The stack upgrades have their own quest line, and each quest follows the one before it. The quest text gives the boost for each tier.^[2]

• Stack Upgrade Tier 1: increases stack size in the backpack by 2.^[2]
• Stack Upgrade Tier 2: increases stack size by 4.^[2]

Backpack upgrades

Almost every other upgrade quest follows the Upgrade Base quest (a quest in "Basic Storage"), which says you need the base to make backpack upgrades.^[2]

The basic upgrades include the Crafting Upgrade, Smelting Upgrade, Blasting Upgrade, Smoking Upgrade, Stonecutter Upgrade, Jukebox Upgrade, Tank Upgrade and Battery Upgrade. The list also has the Pickup Upgrade, Magnet Upgrade, Feeding Upgrade and Void Upgrade. Other quests cover the Everlasting Upgrade, which makes the backpack unable to die, and the Inception Upgrade, which lets you put a backpack inside a backpack.^[2]

Advanced and automatic upgrades

Many basic upgrades have a follow-up quest with the subtitle "More Filtering Options". It asks for the advanced version, such as the Advanced Filter Upgrade, Advanced Restock Upgrade, Advanced Refill Upgrade, Advanced Void Upgrade and Advanced Feeding upgrade. Each advanced quest unlocks after the basic upgrade it improves. The pack's recipes for these upgrade the basic item rather than starting from the Upgrade Base.^[2][3]

The "Automatic" quests ask for the Auto-smelting Upgrade, Auto-blasting Upgrade and Auto-smoking Upgrade. Each follows its manual counterpart, and each has a recipe that upgrades from that manual upgrade. The Experience Pump Upgrade sits at the end of the pump line, after the Advanced Pump Upgrade quest.^[2][3]

One quest also covers the Chipped workbench upgrades, such as the Chipped: Mason Table Upgrade. Its text says they add crafting screens for the Chipped workbenches to your backpack, and any one of the seven satisfies the quest.^[2]

In this pack, Sophisticated Backpacks connects to other mods through crafting recipes: Chipped, Sawmill and Sophisticated Storage. Every recipe below is marked as changed by the pack, so don't assume you'll see the mod's default recipes.^[3]

Chipped workbench upgrades

There is a Backpack upgrade for each of seven Chipped workbenches. They give you the workbench's crafting screen right inside your Backpack.^[2][3]

• Chipped: Alchemy Bench Upgrade^[3]
• Chipped: Botanist's Workbench Upgrade^[3]
• Chipped: Carpenters Workbench Upgrade^[3]
• Chipped: Glassblower Upgrade^[3]
• Chipped: Loom Table Upgrade^[3]
• Chipped: Mason Table Upgrade^[3]
• Chipped: Tinkering Table Upgrade^[3]

Here is the recipe for the Alchemy Bench version. The other Chipped upgrades are crafted the same way, each with its own Chipped workbench.^[3]

It accepts any of the seven upgrades, and its text says it adds crafting GUIs for Chipped Workbenches to your Backpack.^[2]

Swapping upgrades with Sophisticated Storage

The pack lets you convert upgrades between Sophisticated Backpacks and Sophisticated Storage in both directions. There are 40 recipes for turning a Storage upgrade into the Backpack version, and 40 for turning a Backpack upgrade into the Storage version.^[3]

The conversions cover the Filter, Crafting, Compacting, Feeding, Alchemy, Blasting, Auto-smelting and Auto-smoking upgrades, along with their advanced and Chipped versions, among others. Here is the Filter Upgrade going each way.^[3]

Backpack Filter Upgrade to Storage Filter Upgrade, changed by the pack.

Everything for this mod lives in one quest chapter, Basic Storage. It starts with a single backpack and branches into backpack tiers, basic upgrades, and advanced versions of many of those upgrades. Each quest asks you to obtain one item, except one that accepts any of several.^[2]

Where it starts

The chapter opens with "Sophisticated Backpacks" quest, which asks for a Backpack. Its description says backpacks can use filters for extra features, can be worn in your Curios Back slot, and can be dyed. Two quests unlock from there: the backpack tier line and the upgrade base.^[2]

Backpack tiers

1. "Copper Backpack" quest asks for the Copper Backpack. It unlocks after the first quest.^[2]
2. "Iron Backpack" quest asks for the Iron Backpack. It needs both the first quest and the Copper Backpack quest.^[2]
3. "Gold Backpack" quest asks for the Gold Backpack.^[2]
4. "Diamond Backpack" quest asks for the Diamond Backpack.^[2]
5. "Netherite Backpack" quest asks for the Netherite Backpack.^[2]

The upgrade base and basic upgrades

a quest in "Basic Storage" asks for the Upgrade Base, which the quest says you need to make backpack upgrades. Nearly every basic upgrade quest unlocks after it, so you can do them in any order. They are:^[2]

• Storage and handling: a quest in "Basic Storage" (Deposit Upgrade), a quest in "Basic Storage" (Filter Upgrade), a quest in "Basic Storage" (Void Upgrade) and a quest in "Basic Storage" (Compacting Upgrade, which compacts to the 2x2 recipe).^[2]
• Collecting and restocking: a quest in "Basic Storage" (Pickup Upgrade), a quest in "Basic Storage" (Magnet Upgrade), a quest in "Basic Storage" (Refill Upgrade) and a quest in "Basic Storage" (Restock Upgrade).^[2]
• Player helpers: a quest in "Basic Storage" (Feeding Upgrade), a quest in "Basic Storage" (Tool Swapper Upgrade) and a quest in "Basic Storage" (Everlasting Upgrade, which keeps the backpack from dying).^[2]
• Fluids and power: a quest in "Basic Storage" (Tank Upgrade), a quest in "Basic Storage" (Pump Upgrade) and a quest in "Basic Storage" (Battery Upgrade).^[2]
• Crafting and processing GUIs: a quest in "Basic Storage" (Crafting Upgrade), a quest in "Basic Storage" (Stonecutter Upgrade), a quest in "Basic Storage" (Smelting Upgrade), a quest in "Basic Storage" (Blasting Upgrade) and a quest in "Basic Storage" (Smoking Upgrade).^[2]
• Extras: a quest in "Basic Storage" (Jukebox Upgrade) and a quest in "Basic Storage" (Inception Upgrade, which lets you put a backpack inside a backpack).^[2]
• a quest in "Basic Storage" accepts any one of the seven Chipped workbench upgrades, such as Chipped: Mason Table Upgrade or Chipped: Loom Table Upgrade.^[2]

Stack upgrades

The stack upgrades are a separate chain. "Stack Upgrade Tier 1" quest unlocks after the upgrade base and increases stack size in the backpack by 2. Then comes "Stack Upgrade Tier 2" quest (4), "Stack Upgrade Tier 3" quest (8) and "Stack Upgrade Tier 4" quest (16), each unlocking after the previous tier.^[2]

Advanced and automatic upgrades

Most basic upgrades have a follow-up quest titled "More Filtering Options" that unlocks after its basic version. These ask for the advanced item:^[2]

• "Advanced Filter Upgrade" quest for the Advanced Filter Upgrade^[2]
• "Advanced Void Upgrade" quest for the Advanced Void Upgrade^[2]
• "Advanced Deposit Upgrade" quest for the Advanced Deposit Upgrade^[2]
• "Advanced Pickup Upgrade" quest for the Advanced Pickup Upgrade^[2]
• "Advanced Magnet Upgrade" quest for the Advanced Magnet Upgrade^[2]
• "Advanced Refill Upgrade" quest for the Advanced Refill Upgrade^[2]
• "Advanced Restock Upgrade" quest for the Advanced Restock Upgrade^[2]
• "Advanced Feeding Upgrade" quest for the Advanced Feeding upgrade^[2]
• "Advanced Tool Swapper Upgrade" quest for the Advanced Tool Swapper Upgrade^[2]
• "Advanced Pump Upgrade" quest for the Advanced Pump Upgrade^[2]
• "Advanced Compacting Upgrade" quest for the Advanced Compacting Upgrade, which compacts to the 3x3 recipe^[2]

The furnace-style upgrades have their own "Automatic" follow-ups: "Auto-Smelting Upgrade" quest (Auto-smelting Upgrade), "Auto-Blasting Upgrade" quest (Auto-blasting Upgrade) and "Auto-Smoking Upgrade" quest (Auto-smoking Upgrade). Each unlocks after its matching basic upgrade.^[2]

The last quest in the chapter is "Experience Pump Upgrade" quest, titled "Storing XP". It asks for the Experience Pump Upgrade and unlocks after the Advanced Pump Upgrade quest. It lets you pump experience between you and the backpack.^[2]

Everything here lives in the server config file for Sophisticated Backpacks. Every option that lists a mod default is set to that default in this pack, so the numbers below are the stock mod values, not pack tweaks.^[5]

Backpack sizes

Each tier has its own inventory and upgrade slot count. These are the values in this pack:^[5]

• Leather: 27 inventory slots and 1 upgrade slot (server.leatherBackpack.inventorySlotCount, server.leatherBackpack.upgradeSlotCount).^[5]
• Copper: 45 inventory slots and 1 upgrade slot (server.copperBackpack.inventorySlotCount, server.copperBackpack.upgradeSlotCount).^[5]
• Iron: 54 inventory slots and 2 upgrade slots (server.ironBackpack.inventorySlotCount, server.ironBackpack.upgradeSlotCount).^[5]
• Gold: 81 inventory slots and 3 upgrade slots (server.goldBackpack.inventorySlotCount, server.goldBackpack.upgradeSlotCount).^[5]
• Diamond: 108 inventory slots and 5 upgrade slots (server.diamondBackpack.inventorySlotCount, server.diamondBackpack.upgradeSlotCount).^[5]
• Netherite: 120 inventory slots and 7 upgrade slots (server.netheriteBackpack.inventorySlotCount, server.netheriteBackpack.upgradeSlotCount).^[5]

Upgrade limits and ranges

server.maxUpgradesPerStorage caps how many of each upgrade type one backpack can hold. This pack allows 3 stack upgrades, 1 furnace-type upgrade and 1 jukebox upgrade per backpack.^[5]

The basic magnet upgrade picks up items within 3 blocks (server.magnetUpgrade.magnetRange). The advanced magnet reaches 5 blocks (server.advancedMagnetUpgrade.magnetRange).^[5]

The tank upgrade holds 4000 mB per row of storage slots (server.tankUpgrade.capacityPerSlotRow).^[5]

The battery upgrade holds 10,000 FE per row of storage slots (server.batteryUpgrade.energyPerSlotRow).^[5]

The plain smelting upgrade runs at the vanilla furnace speed: its speed multiplier is 1 (server.smeltingUpgrade.smeltingSpeedMultiplier) and its fuel efficiency multiplier is 1 (server.smeltingUpgrade.fuelEfficiencyMultiplier).^[5]

Carrying too many backpacks

server.nerfs.tooManyBackpacksSlowness is false here, so carrying a pile of backpacks does not slow you down. The limit setting is 3 (server.nerfs.maxNumberOfBackpacks), but it only matters if someone turns the slowness on.^[5]

server.nerfs.onlyWornBackpackTriggersUpgrades is false, so active upgrades like magnet and pickup are not limited to the backpack you are wearing. server.allowOpeningOtherPlayerBackpacks is true, so on a server you can right-click another player's worn backpack to open it.^[5]

Mobs wearing backpacks

Mobs can spawn wearing a backpack with a chance of 0.01 (server.entityBackpackAdditions.chance). A mob killed by a player drops its backpack with a chance of 0.5 (server.entityBackpackAdditions.backpackDropChance).^[5]

When a mob does spawn with a backpack, the tier is picked by weight, and the cheap tiers are far more common:^[5]

• Leather: weight 625 (server.entityBackpackAdditions.leatherWeight).^[5]
• Copper: weight 250 (server.entityBackpackAdditions.copperWeight).^[5]
• Iron: weight 125 (server.entityBackpackAdditions.ironWeight).^[5]
• Gold: weight 25 (server.entityBackpackAdditions.goldWeight).^[5]
• Diamond: weight 5 (server.entityBackpackAdditions.diamondWeight).^[5]
• Netherite: weight 1 (server.entityBackpackAdditions.netheriteWeight).^[5]

The list in server.entityBackpackAdditions.discBlockList keeps two Botania Gaia records from being played by backpack-wearing mobs. Mobs getting a jukebox upgrade is off anyway, since server.entityBackpackAdditions.playJukebox is false.^[5]
