BlazeandCave's Advancements Pack

by BlazeandCave

Adds over 900 new advancements organized in custom tabs covering exploration, farming, combat, building, and more. The most popular advancement pack.

Overview

BlazeandCave's Advancements Pack is the most widely used advancement expansion for Java Edition, adding more than 900 custom advancements spread across dedicated tabs for mining, building, farming, combat, the Nether, the End, and beyond. Goals range from gentle early tasks to brutal long-term grinds, and many hand out reward items on completion. Because the advancement tree is so large, a world may show a short load pause the first time the pack initializes. It turns an ordinary survival run into a structured checklist that can occupy hundreds of hours.

Best for completionist survival players and long-running SMP communities who want hundreds of structured goals and rewards layered on top of vanilla. It comes from BlazeandCave, sits in the Challenge category, and is rated a simple, drop-in pack to run. Everything happens through vanilla data pack functions, so no mod loader such as Fabric or Forge is required to use it on Minecraft 1.20 through 1.21.4.

How It Works

Under the hood, BlazeandCave's Advancements Pack relies on plain data pack mechanics rather than any client mod. Here is what happens in-game once it is loaded:

1Hundreds of advancement JSON files define triggers, criteria, and parent links across many custom tabs.
2Completing an advancement fires a reward function that grants items, experience, or trophies.
3Tiered advancements gate harder objectives behind earlier ones to form long progression chains.
4Custom criteria watch events like blocks mined, mobs killed, and biomes entered to fire automatically.

Supported Versions

1.201.20.11.20.41.211.21.4

Compatibility

Compatible with most data packs. Large advancement tree may cause initial lag.

Compatible with most other data packs since it mainly adds advancement and function files rather than overriding vanilla recipes.
The large advancement tree can cause a brief load hitch when a world first applies the pack.
Its optional resource pack is purely cosmetic and is not required for any advancement to be earned.

BlazeandCave's offers an optional companion resource pack that adds custom advancement icons and sounds, and the data pack works fully without it though the visuals look plainer.

How to Install

BlazeandCave's Advancements Pack installs as a standard Java Edition data pack and runs on both singleplayer worlds and multiplayer servers. Recent 1.21 releases bumped the data pack format, so keep the pack's pack.mcmeta in step with your server version.

1.Download the BlazeandCave's Advancements Pack pack as a .zip and keep it zipped.
2.Open the target world folder — a singleplayer save under .minecraft/saves, or the world folder on your server.
3.Drop the .zip into that world's datapacks folder, creating the folder if it does not exist.
4.Load the world (or run /reload if it is already open) and run /datapack list to confirm it is enabled.

The pack is built for Minecraft 1.20 through 1.21.4, so it loads on vanilla Java without Fabric, Forge or any other mod loader. Place the pack in the datapacks folder and reload; for the intended custom advancement icons and sounds, also install its optional companion resource pack.
