Altus Tunnel Location Elden Ring Entrance And Dungeon Rewards
The Altus Tunnel is a critical mid-game side dungeon located within the heart of the Altus Plateau in Elden Ring. Exploring this subterranean mine offers adventurers valuable weapon upgrade materials, crafting supplies, and unique key items. Understanding how to find the entrance and defeat the bosses inside will ensure a smooth journey through this region.
Finding the Altus Tunnel Entrance
To reach the Altus Tunnel location, players must travel directly south from the Minor Erdtree positioned in the central Altus Plateau. The cavern entrance is situated at the base of a cliff face directly across from the Perfumer's Grotto ravine. Navigating the surrounding terrain requires caution as hostile foes patrol the pathways leading toward the cave.
Unlike certain other dungeons in the area, accessing this cavern does not require any Stonesword Keys to unseal. Players can freely step past the entrance threshold and rest at the Site of Grace inside to set a convenient checkpoint. Setting this point of rest makes repeated attempts through the mine much easier.
Navigating the Dungeon Hazards and Enemies
Inside the Altus Tunnel, players face a challenging mix of Glintstone Miners, Marionette Soldiers, and Crystal Snails. The miners actively dig for resources, but they will aggressively attack intruders using heavy pickaxes and fire attacks. Ranged attackers like Marionette Soldiers overhead can easily overwhelm unprepared adventurers.
Caution is advised when traversing the timber scaffolding and narrow ledges within the mine chambers. Striking the crystal miners with blunt or strike-type weapons proves most effective for breaking their tough defense. Taking down enemies methodically allows players to safely loot all the mining nodes scattered around.
Valuable Items and Key Upgrade Materials
The main reason Tarnished explore this dungeon is to gather high-tier weapon reinforcement items. Scattered throughout the mine shafts are numerous nodes yielding Smithing Stone [5] and Somber Smithing Stone [5]. These materials allow players to significantly boost their weapon scaling before taking on major regional bosses.
In addition to raw smithing materials, players can discover essential key loot hidden within storage huts. Defeating the enemies guarding the lower chambers grants access to the Somberstone Miner's Bell Bearing [2]. Handing this bell bearing to the Twin Maiden Husks in Roundtable Hold permanently unlocks purchasing Somber Smithing Stones.
Boss Encounter and Final Rewards
At the deepest point of the tunnel lies a mist door guarding a boss arena housing two Crystalian bosses. One Crystalian wields a spear while the second uses a ringblade to attack from medium range. Using strike weapons or heavy poise-breaking attacks is essential to shatter their outer crystal armor.
Defeating the dual Crystalian encounter rewards players with extra runes and completes the dungeon objectives. Clearing the boss room ensures you have fully emptied the location of its most valuable resources. Completing the run prepares your character with upgraded gear ready for the challenges of Leyndell.
