Altus Tunnel Walkthrough

Take the lift down to the tunnel. There will be a Site of Grace. Leaving the Site of Grace, the first room on the right is a small cavern with 2 enemies within, 1 Sorcerer Miner and 1 Avionette Soldier. The room being small as it is a large AOE attack such as using Cannon of Haima can quickly clear the space safely. The treasure chest within will reward you with a Rune Arc. Moving past this room and following the main tunnel the next space will have a Sorcerer sat on the left side of the room by some sacks. Defeating these enemies will give you a chance to loot a Large Glintstone Scrap.  The room connected on the right has multiple Crystal Snail within as well as a body that will drop Crystal Dart with many Cracked Crystal stored further in the back.

After this first area, you will enter the next section of the tunnels.  You will walk into the main part of the tunnels where miners are working away at the crystals found in the walls. This room has multiple and different kinds of enemies so take the fight slowly to not get surrounded and swarmed. The Avionettes move fast to attack the enemies while the Sorcerers stand afar and on the wooden platforms above the main floor of the tunnel. This room has multiple Smithing Stones for the player to collect both on the ground floor and on the wooden platforms. Notice the Crystals embedded into the rocks as these are also lootable. Loot them to obtain Smithing Stone (5).

As you exit this area, you will enter an open space. Arteria Leaf can be found on a body at the end of the wooden platforms. From this room there is a small tunnel leading to a stone ledge with a connecting wooden balcony area where a crystal snail sits next to a body that can be looted for a Golden Rune (7). If you look up, there will be a Malformed Star that can hurl rocks in your direction. It hangs over giant logs with some lootable items on it. You can choose to clear this enemy with your ranged attacks, but this area is more easily accessed from Perfumer's Grotto.

The image above shows the view of the Altus Tunnel wooden platforms where you are standing from the Perfumer's Grotto. [Elden Ring Map Link

From this area, you can take the largest log up to the higher wooden platform to loot Arsenal Charm +1. Drop back down, move back into the tunnels and take through until you reach the large wooden doors.

The next room of the tunnel is the final room before the boss fight. Many dormant Crystal Snails can be found here before the two large wooden doors that lead to the final room of the tunnel.


BOSS BATTLE: Crystalian Spear  & Crystalian Ringblade

The two bosses are humanoid enemies made of crystal that are not much larger than the player, making the arena quite spacious. The fight can be made much more manageable by using Spirit Ashes to help draw the attention of the bosses as you work on dealing damage to the bosses. A good strategy is to single out and defeat them one at a time.

The Crystalians take reduced damage from all sources until their poise is broken, when they get up you will see that their bodies are visibly cracked and they start to take normal damage. If possible target the Ringblade boss first as they have a more difficult attack pattern to deal with. The Spear user repeatedly hops towards and stabs their spear at the direction of the player ending with a slower large hop giving players lots of time to kite them and an easily timed window to attack them. The Ringblade user is much more mobile and difficult to deal with, attacking from range as well as having a damaging and moving spinning attack. Defeating both bosses will reward the player with the Somberstone Miner's Bell Bearing (2) and 1800 Runes.

      For the crystalline’s flame or the red manes is op. One or two shots and you break their guard once their guard is broken once you can strike them to hell

        For crystalians, either have a striking weapon handy like a mace or hammer, OR you can two hand your preferred weapon, this way your weapon won't bounce, however due to the enemies resistances you'd still be better off using striking

          If you want to kill the centipede dude, use barrage ash of war mixed with poison arrow, take a bit of time and arrow but the dude will eventually die (50 regular arrows, 50 poison, base shorbow).

            I used the Dragonfire incantation on the twin bosses. A little slow so the spear boss creeps up on you but when you pull it off you can deal a big blow to both of them.

              I recommend going to Perfumer's Grotto first next to the big gateway through the outer capital walls. This will allow you to get close to the Malformed Star that you see in the distance from this tunnel and kill it easily so you can easily get to the Arsenal Charm+1.

                Bosses stun locked and staggered easily using Gargoyle Greatsword + Blood Flame. Not sure if weapons mattered.

                  So the sorcerer miner w/ rock bag on bag sitting on the ground beside sacks on the left in the second room leading to the boss (ignoring the deadends) dropped a somber stone 5 first time i killed him.

                      • "From this room there is a small tunnel leading to a stone ledge with a connecting wooden balcony area where a crystal snail stands over a body that can be looted for a Golden Rune." You might want to mention the hanging centipede that slings rocks at you lol

                          Also need to mention, in one of the room with hanging centipede monster, you can climb the root to the top for Arsenal Talisman +1

                            Farmable Somber Smithing stone [4] & [5]:
                            Altus Tunnel Minner (or sorcerer), rarely drops Somber Smithing stone [4] and Somber Smithing stone [5]. There are 2 types of Miner here, I think one of them drop [4] the other one drop [5]. The drop rate is terrible though.

                              Important if you wonder how to reach the rock throwing beast on the ceiling: It´s in a different dungeon called Perfumer's Grotto, you're welcome.

                                Somber Smithing Stone 5 Location: When you go up the wooden staircases in the main room and head towards the dead end with a mage, have a look on the right side, there is one gatherable on the wall.

                                  Any strike-based weapon will do short work of the bosses. With 28 STR and 18 DEX, Grafted Dragon +5 deals around 15% of one's boss full health per 4 strikes combo (without breaking their poise) and around 18%-20% per critical in their back. If you summon something, I suggest you summon one with a shield and focus on the Boss with the Spear as it's the only one who is a real treat to your summon.

                                    The gravity centipede thing on the ceiling can be reached by going in another dungeon - Perfumer's Grotto. Entrance is found on the left cliff wall when facing the road leading up to the double Tree Sentinel fight (road into the capital from the Dectus Lift)

                                      Ash summons are not accessible during this boss fight. Probably just a cut-and-paste paragraph from someone not paying attention.

                                        Guard counter the spear guy and jump attack spam the beyblade guy. You CAN get the arsenal charm +1 from here if you jump down and then run up the tree roots. Kill the moth bat thing with arrows, kukris, or frenzied burst/sorceries. You can’t get to the other side thoufh.

                                          Bosses take very little damage until their poise is broken. take out ring throwing boss first. ez pz after

                                          • Lootable items: Smithing Stone (5) x7, Rune Arc x1, Crystal Dart x8, Arteria Leaf x2, Golden Rune (7) x1, Glintstone Scrap x, and you can farm Cracked Crystals.

                                              The other side that can be seen where you fight the hanging monster is the Perfumer Hideout which can be found just east of the Atlas Highway Junction grace point. The entrance to the cave is north of the bridge/walkway.

                                                Arsenal charm +1 is also in here, it's on the top of a platform after you climb the branch from the place you first see that "gravity fly"

                                                  what about the big monster hanging from the ceiling that you have to kill with arrows? After it dies, how do you get up there?

                                                  • There's likely a way to kill the gravity fly sorcerer thing - if you look, there's a tree branch behind it (not the one you climb on), that has two alcoves. There's a secret wall somewhere, or something...
