Elden Ring Altus Tunnel Location Guide: How To Complete

Elden Ring Altus Tunnel is a side dungeon found in the Altus Plateau region and the home of the two bosses: Crystalian (Spear) and Crystalian (Ringblade).

Altus Tunnel is worth a visit for its loot, which includes Arteria Leaf, Rune Arc, Arsenal Charm +1, Somberstone Miner’s Bell Bearing [2], and many other items.

The Perfumer’s Grotto dungeon may be seen from the Altus Tunnel, and while they appear to be connected, they are not.

Throughout this guide, we will show you where to find the Altus Tunnel and walk you through it so you don’t miss any items.

Altus Tunnel can be found directly south of the Minor Erdtree in the Altus Plateau region.

Once inside, take the lift down to the tunnel and rest at the Site of Grace.

As you leave the Site of Grace, you will encounter two enemies inside in the first room on the right, one Sorcerer Miner and one Scavenger.

After defeating them, open the chest to receive a Rune Arc and gather the Smithing Stone [5] behind the barrels on the west side of the room.

In the next area, you will encounter a Sorcerer seated on the left side of the room near several bags.

The room on the right has many Crystal Snails, a body that holds 8 x Crystal Dart, and a large amount of Cracked Crystal tucked further back.

After this, you will enter the mining area of the tunnels, where miners are extracting crystals from the walls.

Elden Ring Altus Tunnel Location Mining Cave

There are a good number of Smithing Stones and Cracked Crystal deposits here.

Before going deeper into the cave, take your time collecting them all.

Also, this area contains a variety of enemies, so fight them slowly to avoid being cornered and swarmed.

After killing all the Marionette Gargoyles and the Scavengers on the first floor, make your way up the wooden stairs and onto the platform.

Eventually, you will come to a dead-end, and a corpse can be found nearby.

Loot it to collect 2 x Arteria Leaf.

Find your way back down, take the tunnel to the south, and you will enter a large cavern.

Turn right and defeat all the Crystal Snails you encounter. When you’ve finished dealing with them, loot the nearby corpse to get a Golden Rune [7].

Drop down from the ledge to the branch below and defeat all the Crystal Snails.

At the end of the platform, behind the Crystal Snail and the wooden slats, you will notice a corpse hanging on the edge of the wooden platform. Loot it to receive 6 x Glintstone Scrap.

Now, climb to the very top, and you will find a corpse holding the Arsenal Charm +1.

Pick it up, drop down on the platform, and return to the mining cave.

Taking the tunnel to the east will lead you to a room full of Crystal Snails; kill them all.

Open the double doors beyond the room to enter the bosses’ chamber.

Here you will have to face both Crystalian Spear and Crystalian Ringblade bosses.

The Crystalian bosses take less damage from all attacks until their poise is broken.

Use a spirit summon to draw one of the bosses’ attention, allowing you to take them down one at a time.

It’s better to begin with the Ringblade Crystalian.

After defeating both bosses, you will receive 9000 Runes and the Somberstone Miner’s Bell Bearing [2].
