Collections

Collect armor, fish, and any other set of items you describe. Finish the set and the server pays the reward: XP, items, attribute bonuses, status effects, slower hunger, a trophy, or a command.

Open the Codex with K, or craft the book (a book plus an armor stand) and use it. The left page is the list of collections. The right page is the reward and the items still missing.

Collection Stand

Armor collections are filled by displaying the pieces, not by leaving them in a chest.

Craft a Collection Stand from sticks and planks. Place it, then right-click with a helmet, chestplate, leggings, or boots. One piece sits in that slot. Right-click the same height with an empty hand to take it back. The stand is a block, so a room full of them does not add armor-stand entities.

Wolf armor, horse armor, nautilus armor, and the elytra are not accepted.

With the default settings, a piece you have put on a stand stays registered after you take it off. Creative mode does not register anything unless you turn that limit off.

Built-in collections

A new world writes these for you. Armor is collected on a stand. Fish are collected by fishing them up.

Armor

• Leatherworker — leather helmet, tunic, pants, boots
• Scavenger — the four chainmail pieces
• Ironclad — the four iron pieces
• Gilded — the four golden pieces (golden_helmet, golden_chestplate, golden_leggings, golden_boots)
• Gem Knight — the four diamond pieces
• Netherite Knight — the four netherite pieces
• Treasure Hunter — on a normal world, the chainmail chestplate
• Master Collector — every vanilla humanoid armor piece, including the turtle shell. Copper armor is part of this on 1.21.9, 1.21.10, and 1.21.11.

Fishing

• Angler's Log — raw cod, salmon, tropical fish, and pufferfish
• Treasure of the Deep — bow, enchanted book, fishing rod, name tag, nautilus shell, saddle
• Junk Collector — lily pad, bowl, leather, leather boots, rotten flesh, stick, string, potion, bone, ink sac, tripwire hook

If another mod adds armor, it gets its own collection. If another mod adds items to the #minecraft:fishes tag, those fish get one too. The example collections (food, tools, music discs, a mixed armor set) are installed turned off, ready to copy.

Rewards

Each collection lists its rewards in the book.

While a collection is complete, it can grant extra armor or other attributes, a status effect, or hunger that drains more slowly. Those stop if the collection stops being complete.

Once per player, it can grant XP, items, a named trophy, or a command run by the server. The bundled Netherite Knight and Master Collector collections include trophies. Master Collector also shows a title card.

Make your own

Collections live in config/collections/sections/ as JSON. You can list exact items, use a * wildcard, use an item tag, or name an armor set such as minecraft:gold or minecraft:turtle. Choose whether an item counts when it is placed on a stand, present in the inventory, or fished up.

config/collections/settings.json controls creative mode, the blacklist, sort order, and how strict the treasure rule is. Operators reload with /collections reload. /collections progress, /collections find, /collections reset, and /collections blacklist are the other commands. Reload, reset, and blacklist require operator level 2.

A datapack or another mod can ship a collection in data/<namespace>/collections/sections/. The server config overrides it.

Versions

Minecraft 1.21.1 through 1.21.11, on Fabric and NeoForge. Each version has its own Fabric jar and its own NeoForge jar. Use the jar whose name matches the game, for example collections-fabric-1.0.0+1.21.4.jar. Install the same jar on the client and the server.

Fabric also needs Fabric API and Architectury API. NeoForge needs Architectury API. Use the Architectury build for that Minecraft version.

Bugs

Report a bug or request a feature on the CurseForge page. Upload latest.log or the crash report to mclo.gs and include that link. Include the Minecraft version, Fabric or NeoForge, the Collections version from the jar name, other mods or the modpack, what you did, and what you expected.
