Sellia Crystal Tunnel - Elden Ring Guide - IGN (2024)

Sellia Crystal Tunnel is one of the Minor Dungeons found in the Caelid Region in Elden Ring. It is an optional dungeon that is home to a few treasure items and a miniboss Foe. This page contains information on the location, walkthrough, and guide to traverse this dungeon, locate all of its treasure, and tips to defeat the enemies within.

How to Get to Sellia Crystal Tunnel

You can actually reach this Dungeon very early in the game, despite being in Caelid. If you open the chest in Dragon-Burnt Ruins in Lake Agheel, Limgrave, you'll be teleported partway into this dungeon.

You can also naturally find this Dungeon by heading diagonally northwest from Sellia, Town of Sorcery. The entrance to the cave will be visible thanks to a brazier outside, and is buried in the cliff face relatively close to the westernmost walls of Sellia.

Through a short tunnel, you'll emerge into a cave with a Site of Grace.

Sellia Crystal Tunnel Walkthrough

To the left of the Site of Grace is a corpse in the corner that holds... . After climbing the ladder to the right of the room, you'll head up a slope into a large cavern with Crystal Miners and 2 Lesser Kindred of Rot. There are dozens of Cracked Crystal deposits to gather in this room, as well as some Smithing Stone (5) deposits along the left-hand side of the room. In the wooden shack down to the left, a corpse holds a Golden Rune (5).

Continuing up the slope curving around to the right, you can loop into another wooden shack (the one you teleport into should you get here via Dragon-Burnt Ruins) and a chest is in the corner that contains... At the top of the slope, there is another Crystal Miner to the right and a Lesser Kindred of Rot on the wooden platform to the left. There is a corpse on the edge of this wooden platform that holds a Rune Arc.

You can then drop off the edge of this wooden platform and take out the Crystal Miner on the wooden platform one level down, then drop down on top of the first wooden shack to loot a corpse holding Glintstone Scrap x6.

Back at the top of the slope, grab the Cracked Crystal and Smithing Stone (5) deposits where the Crystal Miner was, then turn around to look back down the slope. You'll note you can perform a running jump onto the higher wooden shacks roof, then across to another wooden platform on the opposite side of the room which allows you to bypass the debris blocking the path to the east.

Upon doing so, you can jump across the top of the debris to reach the corpse draped over the pole and receive a Cuckoo Glintstone. Progressing up this new slope, you'll face a Crystal Miner. At the top, you'll open out into a room with a ladder to the right. Head up it and do a 180-degree turn to cross over a wooden plank and loot a sitting corpse holding a Somber Smithing Stone (4).

Proceeding into the next room, you'll be above the initial cave room. A Lesser Kindred of Rot will be on the roof across the room, as well as a Crystal Miner to the right. Cross over and defeat them to head into the shack and grab the Rock Blaster spell from the chest inside. There are two Smithing Stone (5) deposits in the northeast corner of the cave. Looping around the left side of the shack, you can climb the ladder at the end of the walkway to face off against two Crystal Miners, and grab the Golden Rune (4) on the corpse sitting on the ledge. Be sure to kick the ladder directly in front of the corpse to allow a shortcut should you need it. In the northwest corner is a Somber Smithing Stone (5) deposit.

Continue through the tunnel nearby to reach a new cave. In the alcove to the left of the corpse on the floor that you'll be able to spot from a distance is a Lesser Kindred of Rot waiting to ambush you, so be ready for it to jump out. The aforementioned corpse holds Dragonwound Grease. In the alcove the Kindred of Rot came from is a Somber Smithing Stone (4) deposit. Up the steps to the right of the corpse are two more Lesser Kindred of Rot, which you can sneak up to one of and get the drop on. The corpse that the Kindred of Rot were praying in front of holds the Faithful's Canvas Talisman. To the left is a Smithing Stone (5) deposit.

Head down the tunnel to the west and open the wooden double doors to face a boss.

Boss Fight - Fallingstar Beast

A bull-type animal with mandibles and a tail, this creature is covered in crystals that act as a protective armor. Because of the size of the Beast and the limited size of the arena, you'll need to do some smart maneuvering and dodging to stay on top of the situation.

The main attacks that the Beast performs are swiping its head back and forth, and an attack where it opens up its mandibles to bite at you. A key one to avoid is the charge attack, where the Beast essentially revs up and charges in a straight line across the arena three times, changing directions at the end of each of the charges. You'll need to be careful timing your rolls, as too early or too late and the Beast will steer into you during the charge.

The other key attack to avoid is the Beast's gravitational moves, to either create a radius around itself causing things to levitate, or using the gravity to summon rock shards from the ground that can pierce you and/or send you flying into the air. Both of these gravitational attacks are telegraphed as the Beast conjures purple lightning around its mandibles, or the sparks appearing on the ground to signal the radius.

Upon defeating the Fallingstar Beast, you'll earn Gravity Stone Chunk x4, a Somber Smithing Stone (6), Smithing Stone (7) x5, and the Somberstone Miner's Bell Bearing 1.
