Why You See No New Items or Empty Slots

Players often load into a world with Curios API expecting to craft backpacks, magic rings, or charms right away, only to find nothing new in Creative mode or no slots appearing.

What Curios API Actually Adds

By itself, Curios API works strictly behind the scenes. It does not add any blocks, mobs, or wearable items to Minecraft. Its sole job is to create the extra inventory framework so other mods have a standardized place to put their special gear.

If you run Curios API alone without any companion content mods:

• Searching the Creative inventory will not turn up any new rings, belts, or amulets.
• The extra slot panel may show no active equipment spaces because no installed mod has requested a ring, charm, or back slot yet.

Fixing Missing Slots

1. Check your active mod list from the main menu or your mods folder to confirm you also have a content mod installed that uses accessory slots (such as adventure or magic mods like Ice and Fire).

2. Load into a world and acquire an accessory item from that content mod.

3. Open your survival inventory and click the button next to your character model.

4. Look at the side panel to see the specific slots registered by your other mods, then place your item inside.
