Elden Ring Sellia Crystal Tunnel is a minor dungeon found north of the Inner Aeonia Site of Grace in Caelid.
The Elden Ring Sellia Crystal Tunnel dungeon is quite linear and relatively easy to complete, provided you don’t get ambushed by the mobs you’ll find inside.
While exploring it, you’ll find a large number of Smithing Stones as well as the Faithful’s Canvas Talisman.
So, in case you need help navigating the Sellia Crystal Tunnel in Elden Ring, we’ll tell you everything you need to know about it throughout the following guide.
Elden Ring Sellia Crystal Tunnel Location – Where To Find
On the map below, you can see that in the video game developed by FromSoftware, Sellia Crystal Tunnel is located northeast of Abandoned Cave and northwest of Sellia Town of Sorcery, where you complete Gowry’s request.
The entrance to the dungeon is several steps away from the Invisible Teardrop Scarab that drops the Poison Armament Incantation.
You should be able to spot it in the mountain’s wall.
Get inside the dungeon and activate the Sellia Crystal Tunnel Site of Grace.
Sellia Crystal Tunnel Dungeon Guide – How To Navigate
Upon activating the Site of Grace in the same cave, look around to spot a corpse you can loot for some Rot Grease.
You should be able to spot it on the wall that is opposed to a ladder you’ll have to climb next.
Once you get to the upper tunnel, keep following it (there is only one way forward), and you’ll reach a rather large cave with some miners inside.
It is worth pointing out that while the miners are pretty weak, their guards are resilient and fast, capable of inflicting a lot of damage, especially with their range attacks.
So, tread carefully here and dispatch them one by one. Once you clear the ground area, look around for a lot of Cracked Crystals (blue) and Smithing Stones (yellow crystals).
Now, make sure you check the wooden hut on the left side (marked below) and loot the corpse you find here for a Golden Rune.
Also, there is another Smithing Stone behind this hut. Once you’re done clearing the ground, climb the small hill (marked above by the arrow on the right), then turn left to see another corpse.
It is on the roof of the previous building, and if you loot it, you’ll get a Glintstone Scrap.
From this roof, check the other hut in the upper section, and inside, you’ll find a chest containing three Gravity Stone Chunks and six Gravity Stone Fans.
Next, you’ll want to keep following the path that leads up, and here you’ll want to deal with one last guard and loot the corpse at the end of the wooden platform below.
Once you get the Rune Arc from the corpse above, it’s time to find a way to progress through this dungeon because the tunnel ahead is blocked.
Caelid Sellia Crystal Tunnel Blocked Path – How To Progress
To progress through the first cave in Elden Ring Sellia Crystal Tunnel, you have to do a bit of jumping.
Specifically, from the upper section, you’ll need to jump on the roof of the shack on the right side as you face the blocked tunnel. You can see the said roof in my screenshot.
Upon reaching the roof, head left, jump on the wooden platform, and then go over the wooden fence to get inside the next cave.
Don’t worry if you can’t get to the corpse on the wooden beam because you’ll get another chance.
For now, stick to the tunnel ahead, kill the miner and loot all crystals.
Eventually, you’ll reach a smaller cave. Hop on the ladder on the right side, and when you get to the top, turn around to spot another corpse you can loot.
Walk on the wooden beam, get the Somber Smithing Stone from the corpse, then retrace your steps and head inside the next cave.
The moment you cross the wooden planks towards the roofs, turn right, and you’ll spot the corpse hanging on the wooden beam.
Drop on the wooden platform (pictured), loot it to get five Cuckoo Glintstones, drop below and go through the small cave again, returning to the roofs.
Now, you’ll want to check the small shack that’s on the left side the moment you cross the planks, and inside you’ll find a chest containing the Rock Blaster Sorcery.
After getting it, head right, go around the corner, and climb the ladder to the next roof.
Upon dispatching the sleeping miners, loot the corpse at the edge of the roof, then drop the ladder next to it (pictured).
By dropping this ladder, in case you die while fighting the boss, you’ll be able to take a shortcut from the Site of Grace.
Now, go through the next tunnel, and you’ll reach a new cave.
On the ground in front of a shack is another corpse, but be advised that you’ll be ambushed by a guard waiting for you inside the hut on the left as you enter.
After dealing with him, get the Dragonwound Grease from the said corpse, then check the hut where the guard was hiding.
Finally, look for another corpse on the platform where two guards are praying, and on the corpse here, you’ll find the Faithful’s Canvas Talisman.
Get ready to fight the Fallenstar Beast behind the large wooden gate in the next cave upon getting this last item.
The Fallenstar Beast boss has the head of a bull and the tail of a scorpion, and it hits pretty hard. Try to keep a safe distance because it can also levitate you.
After you defeat the Fallenstar Beast in Elden Ring Sellia Crystal Tunnel, you’ll obtain:
- 1 X Somber Smithing Stone 
- 5 X Smithing Stone 
- 10 X Gravity Stone Chunk
- Somberstone Miner’s Bell Bearing 
If you wonder how to use the Somberstone Miner’s Bell Bearing in Elden Ring, the answer is simple. Bring it to the Twin Maiden Husks in Roundtable Hold.
