Sellia Crystal Tunnel is a minor Elden Ring dungeon found north of the Inner Aeonia Site of Grace in Caelid. The Elden RingΒ Sellia Crystal Tunnel dungeon is quite linear and relatively easy to complete, provided you donβt get ambushed by the mobs youβll find inside. While exploring it, youβll find a large number of Smithing Stones as well as the Faithfulβs Canvas Talisman.
So, in case you need help navigating the Sellia Crystal Tunnel in Elden Ring, weβll tell you everything you need to know about it throughout the following guide.
Where To Find Sellia Crystal Tunnel
On the map below, you can see that in the video game developed by FromSoftware,Β Sellia Crystal Tunnel is located northeast of Abandoned Cave and northwest of Sellia Town of Sorcery, where you complete Gowryβs 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 on the mountainβs wall.

Get inside the dungeon and activate the Sellia Crystal Tunnel Site of Grace.
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 youβll have to climb next. Once you get to the upper tunnel, keep following it (there is only one way forward), and youβll 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 youβre 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, youβll get a Glintstone Scrap. From this roof, check the other hut in the upper section, and inside, youβll find a chest containing three Gravity Stone Chunks and six Gravity Stone Fans.

Next, youβll want to keep following the path that leads up, and here, youβll 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, itβs time to find a way to progress through this dungeon because the tunnel ahead is blocked.
How To Progress Past the Tunnel-Blocked Path
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, youβll need to jump on the shackβs roof 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. Donβt worry if you canβt get to the corpse on the wooden beam because youβll get another chance.
For now, stick to the tunnel ahead, kill the miner, and loot all crystals. Eventually, youβll 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 youβll 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, youβll want to check the small shack thatβs on the left side the moment you cross the planks, and inside, youβll 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, youβll be able to take a shortcut from the Site of Grace. Now, go through the next tunnel, and youβll reach a new cave.
On the ground in front of a shack is another corpse, but be advised that youβll 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, youβll find the Faithfulβs 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, youβll obtain:
- 1 X Somber Smithing Stone [6]
- 5 X Smithing Stone [7]
- 10 X Gravity Stone Chunk
- Somberstone Minerβs Bell Bearing [1]

If you wonder how to use the Somberstone Minerβs Bell Bearing in Elden Ring, the answer is simple. Bring it to the Twin Maiden Husks in Roundtable Hold.
