Ultimate 2025 Chasm Fossil Hunt Guide: Primogems & Sumeru Secrets!

OMG fellow Travelers! Just spent my whole weekend digging into the Paleontological Investigation in The Chasm quest again – seriously, this hidden gem in the Underground Mines is STILL one of the most rewarding (and kinda sus) world quests in 2025! Low-key forgot how fun fossil hunting could be until I dusted off my Kamera gadget. If you haven't done this yet, you're missing out on primo Primogems and that sweet, sweet Academia Letter for Sumeru! Let's get into it, no cap. 😎

Starting Your Dino Detective Arc 🕵️♂️

First things first – you gotta find my man Khedive chillin' at the Underground Mines base camp. Don't even need the quest active! Just snap a pic of ANY Strange Rock Fossil (they glow like crazy, can't miss 'em) and show it to him. Bro gets hyped AF and reveals they're legit fossils! Your mission? Track down all five. Pro Tip: Finish the "The Chasm Delvers" questline first to unlock the whole map, and max out your Lumenstone Adjuvant – trust me, the Dark Mud areas are still a pain in 2025 without it!

Fossil Locations: The Ultimate Treasure Map 🗺️

Alright, buckle up! Here's the 411 on all five fossil spots, updated for 2025 traversal:

1. Fossil #1 - Ad-Hoc Main Tunnel:

   • Teleport to the waypoint RIGHT of the tunnel.

   • Head south across the bridge.

   • Watch out! Treasure Hoarders guard it on a wooden dock. SMH, they still tryna steal fossils?

2. Fossil #2 - North of Main Mining Area:

   • Go north from the mining area teleport.

   • Follow platforms up and over the small lake. Easy peasy!

   

3. Fossil #3 - Underground Waterway (The Tricky One!):

   • Teleport to Underground Waterway.

   • Head UP towards the waterfall section.

   • Secret Sauce: Activate the Anemo totem! Ride the wind current all the way UP to a hidden rock platform at the cavern's peak. Took me 3 tries, ngl. 😅

4. Fossil #4 - Left Tunnel in The Glowing Narrows:

   • Find the tunnel to the LEFT in Glowing Narrows.

   • Go ALL the way to the end, past any Lumenstone Ore spots. It's tucked away!

5. Fossil #5 - South of Underground Waterway:

   • Follow the stream SOUTH from the Waterway teleport.

   • You'll find Hilichurls having a dance party (💃) right in front of the fossil wall. Cringe but harmless!

Reporting Back & Getting That BAG 💰

Once you've got all five pics (flex that Kamera skill!), bounce back to Khedive. Here's where it gets juicy:

BIG BONUS ALERT! 🚨 If you're a completionist like me and already smashed the "Mycological Investigation" and "Hydrological Investigation" quests (which you totally should, they're fire), Khedive drops the Academia Recommendation Letter. This ain't just some dusty old paper in 2025! It's your VIP pass for smoother sailing and extra lore crumbs in Sumeru – trust, it opens doors you didn't even know existed. Absolute game-changer!

Final Pro Tips for 2025 Hunters:

• Kamera Ready: ALWAYS have it equipped! The glow makes spotting fossils easier, quest or not.

• Map is Key: Seriously, finish "The Chasm Delvers" first. Navigating blind? Big yikes.

• Lumenstone MVP: Level 6+ Adjuvant makes Dark Mud a joke. Don't skip!

• Combo Quest: Do ALL three "Investigation" quests for the full reward stack. Efficiency is king!

So yeah, that's the fossil tea! This quest is low-effort, high-reward – perfect for grinding those Primogems and prepping for deeper Sumeru adventures. Go grab those fossils, claim your loot, and tell Khedive I sent ya! Happy hunting, Travelers! ✌️
