Understanding the AndesiteDrop Datapack for Skyblock Modpacks
Minecraft’s modding scene constantly evolves, and skyblock challenges remain one of the most beloved ways to test your creativity and survival skills. When you combine a skyblock map with the engineering depth of the Create mod, resource generation becomes a puzzle. The AndesiteDrop datapack steps in to solve a specific, early-game bottleneck: obtaining andesite without relying on traditional sieving methods. Originally designed for the SkyCreblock modpack, this lightweight datapack tweaks a few core mechanics to keep progression smooth and intentional.
What Exactly Does AndesiteDrop Change?
At its heart, AndesiteDrop modifies the loot table of cobblestone. In a standard Minecraft world, mining cobblestone never yields andesite. This datapack introduces a 5% chance for andesite to drop alongside cobblestone when you break the block with a pickaxe. That small percentage might seem insignificant, but in a skyblock setting where every resource is precious, it becomes a reliable, passive source of andesite over time.
Why is andesite so critical? In modpacks featuring the Create mod, andesite is the foundational material for crafting andesite alloy, which is then used to build shafts, cogwheels, and other mechanical components. Without a steady supply, your entire tech tree grinds to a halt. The datapack ensures you are not forced to wait for rare sieving drops or explore nonexistent caves.
The Sieving Overhaul: Ex Deorum Compatibility
Many skyblock modpacks rely on Ex Deorum (a modern fork of Ex Nihilo) for sieving materials from gravel, sand, or dust. Normally, sieving can produce andesite, but AndesiteDrop deliberately removes andesite from all sieving outputs. This design choice pushes players toward the new cobblestone-mining mechanic as the sole method of obtaining the block. It creates a more active gameplay loop: you must build a cobblestone generator, mine it repeatedly, and slowly accumulate andesite, rather than passively waiting for a sieve to finish.
This change also balances the early game. Sieving becomes focused on other ores and resources, while andesite becomes a reward for manual labor. The datapack integrates seamlessly with Ex Deorum’s configuration, so you won’t need to edit any JSON files yourself. Just drop the datapack into your world’s datapacks folder, and the sieving tables are automatically adjusted.
Why SkyCreblock Needed This Custom Solution
The SkyCreblock modpack is built around a skyblock world where doInsomnia is set to false, meaning phantoms won’t spawn and insomnia mechanics are disabled. World generation is set to produce a classic void skyblock map, leaving you with a tiny starting island and a tree. In this environment, every crafting ingredient must be obtainable through renewable means. The pack author realized that relying on Ex Deorum sieves for andesite created an inconsistent experience—sometimes you’d get it quickly, other times you’d be stuck for hours.
By shifting andesite acquisition to cobblestone mining with a fixed drop chance, the progression becomes predictable. You can calculate roughly how much cobblestone you need to break to get enough andesite for your first Create contraptions. It also encourages building an early-game cobblestone generator, which is a classic skyblock staple anyway.
Installing the AndesiteDrop Datapack
Adding this datapack to your game is straightforward. Download the AndesiteDrop.zip file and place it into the datapacks folder inside your Minecraft world save. If you’re creating a new world, you can do this before first launch. For an existing world, just drop it in and run the /reload command. The changes take effect immediately—no need to restart the server or client.
If you prefer a more streamlined approach to mod and datapack management, using a dedicated launcher can simplify the process significantly. For instance, the foxygame.net launcher lets you browse and install datapacks and mods directly from its built-in menu, automatically placing files in the correct directories so you can jump into your skyblock adventure without digging through folder structures. It’s a modern, flexible tool that keeps your Minecraft setup organized and up to date.
Fine-Tuning the Experience
While AndesiteDrop is designed to work out of the box, you can tweak the drop chance if you’re comfortable editing loot tables. The 5% value is stored in the datapack’s cobblestone.json loot table. Changing the weight or adding conditions can adjust how frequently andesite appears. However, for most players, the default balance is spot-on—enough to keep you moving forward without flooding your inventory.
Remember that the datapack only affects regular cobblestone. Stone, cobbled deepslate, and other variants remain untouched. This specificity prevents unintended side effects in other parts of the modpack. If you’re using a cobblestone generator that produces stone instead of cobblestone (like one using a silk touch pickaxe), you won’t get andesite drops—so stick to a standard generator design.
Is AndesiteDrop Right for Your Modpack?
Even if you aren’t playing SkyCreblock, this datapack can be a valuable addition to any skyblock or custom modpack that uses Create and Ex Deorum. The core idea—bypassing RNG-heavy sieving for a critical resource—can be applied to other materials too. It demonstrates how small loot table modifications can dramatically improve game flow without requiring heavy scripting or new blocks.
For modpack developers, AndesiteDrop serves as a clean example of how to solve progression deadlocks. By isolating a single resource and giving it a clear, active acquisition method, you respect the player’s time while maintaining challenge. The removal of sieving drops also shows how to nudge players toward intended gameplay loops without outright disabling mod features.
Final Thoughts
The AndesiteDrop datapack may seem like a tiny tweak, but in the context of a skyblock world powered by Create, it’s a game-changer. It transforms the early-game grind from a frustrating wait into a tangible goal: mine cobblestone, collect andesite, build your first machines. The integration with Ex Deorum sieving and the SkyCreblock modpack’s custom settings proves that thoughtful datapack design can elevate the entire player experience. Whether you’re a modpack author or a player looking to smooth out your skyblock journey, this datapack is worth adding to your world’s datapack folder—and with tools like the foxygame.net launcher, getting it set up is easier than ever.
