Sellia Crystal Tunnel: Walkthrough

Begin by heading up to and activating the Site of Grace, this mining tunnel has its fair share of deadly surprises. You'll be subjected to one of this cave's favourite tricks right out the gate – presenting you with a branching path with one such path leading nowhere. That's the case in the Site of Grace chamber, so continue up the ladder and into the open chamber ahead without fear that you're missing out.

Things can get dicey in this area real fast, so think twice before swinging away at the miners right in front of you. Your first priority here should be to climb up the rocks onto the wooden shed and take out the insectoid enemy. If you don't do so right away, its ranged attacks will melt right through your health. As soon as you take it out, ascend further up the rocks and onto another wooden shed to take out yet another insect enemy.

Now there's only one insect enemy left in this area – one overlooking the cave from a wooden scaffold up above. Head up there and take it out to officially alleviate yourself of the headaches their nasty ranged attacks can cause. This chamber is now yours for exploring.

Grab some of the yellow Smithing Stones [5] along the cave walls whenever you see them, and enter the wooden building you initially ran on top of to find a Golden Rune [5]. Feel free to start sweeping the ground floor, taking the crystal miners out one at a time, and grabbing the Cracked Crystals they're mining. The miners usually won’t pay much mind to you unless you grab their ore in front of them, so take advantage by starting each one off with a backstab if you plan on engaging.

After looting the chamber to your liking, it’s time to progress over some rubble. Jump on one of the easily accessible wooden building roofs, then over to a scaffold, then finally over a caved-in wooden building’s entrance. If you time your jump just right, you can make it to the beam with the corpse holding an item, but don’t fret if you miss as there’s an easier way to get it up ahead.

Enter the next chamber prepared to engage an enemy mage who awaits you on the right. Take him out, continue up another ladder, and circle around the wooden platform to snag a Somber Smithing Stone [4]. The next encounter in the section of the cave chamber is a little tricky. Another insectoid sits atop the wooden building waiting to strike, while a mage is positioned directly around the building’s right corner.

The safest strategy is to sprint into the building to prevent the insectoid’s projectiles from hitting you, take out the mage, bait out the insect enemy to eliminate it next, and finally loot the spoils from the chest which contains the Rock Blaster spell. Up here is a much better angle to drop down onto the beam with the corpse we mentioned earlier which holds a Cuckoo Glintstone.

Keep an eye out for more yellow Smithing Stones [5] along the walls and silver Somber Smithing Stones [4] as you ascend the next short wooden ladder and take out the two crystal soldiers who are sitting here. Grab a Golden Rune [4] from the corpse and be sure to kick down the ladder next to it for a nice little shortcut back up here in the future. It'll prove especially useful for multiple attempts against the Fallingstar Beast at the end of this tunnel.

Continue onward underneath the wooden archway, but don’t fall for the shiny item bait as another insectoid is waiting to pounce on you off to the left. Take it out and grab the Somber Smithing Stone [4] off the wall before grabbing the Dragonwound Grease from the corpse. Next up are a couple more insect enemies that should still be unaware of your presence. Take advantage of this with a charged heavy attack which should give you the advantage. With them both defeated, you’re free to grab the Faithful’s Canvas Talisman off the corpse.

The following chamber is the last one before the boss fight. Make sure you’re healed up prior to opening the wooden doors. Although there’s a branching path in front of the boss doors, yet again it leads nowhere. Take a deep breath, open those double doors, and continue onto one of the tougher optional bosses in Elden Ring.
