Trinkets & Artifacts — Quick Reference
The mods that fill your Curios slots (the extra ring/necklace/belt/charm slots in your inventory). Tutorial with tactics: the Trinkets, Artifacts & Relics guide.
The treasure
Artifacts — unique found-never-crafted wearables (night vision goggles, running shoes, digging claws, cloud in a bottle…) hidden in world loot — and guarded by Mimics, the chests that bite back. → CurseForge — the page lists every artifact and its effect
More Artifacts — extends the pool with additional artifact items in the same spirit. → CurseForge
Celestial Artifacts / Grim’s Artifacts — two more artifact packs seeded through dungeon and boss loot. → Celestial Artifacts
Artifact Crafting — adds recipes to target specific artifacts instead of praying to loot tables. JEI an artifact to see if it’s craftable.
Relics — the leveling trinkets — covered in the Magic reference (they’re as much spellcraft as treasure).
Wearable utility
Radiant Gear + Curious Lanterns — wear a lantern on your belt: permanent light with both hands free. The single biggest quality-of-life trinket in the pack. → Radiant Gear · Curious Lanterns
Under the hood
Curios / Accessories / A Little More Curios — the slot frameworks plus a few extra slots for the pack. Infrastructure, not content. → Curios on CurseForge
