Upgrading your weapons is the fastest way to boost damage and survive the harsh encounters in Elden Ring. To push your standard weapons from +15 to +18, you need Smithing Stone [6].

Whether you need a quick pickup for a specific build or want an unlimited supply to test multiple weapons, here is every reliable way to farm and buy Smithing Stone [6].

What Does the Number [6] Mean?

In Elden Ring, standard weapons require Smithing Stones to level up, categorized into tiers from [1] through [8]. Each tier corresponds to a specific upgrade threshold:

• Smithing Stone [1]–[5]: Upgrades weapons from +0 to +15
• Smithing Stone [6]: Upgrades weapons from +15 to +18
• Smithing Stone [7]–[8]: Upgrades weapons from +18 to +24

When you see Smithing Stone [6], it refers to the tier required to push mid-to-late-game weapons through the +15 to +18 damage threshold. You will need a total of 12 Smithing Stones [6] to upgrade a single weapon through this range (2 for +16, 4 for +17, and 6 for +18).

Best Early Pickup Spot: Altus Tunnel

If you just reached the Altus Plateau and need upgrade materials fast, Altus Tunnel is your best destination.

• Location: Directly south of the Minor Erdtree in the Altus Plateau.
• Farming Method: Explore the tunnel walls and mine the glowing yellow crystal deposits. You can pick up several guaranteed Smithing Stone [6] nodes without fighting the boss.
• Tip: Bring a strike-weapon (like a mace or club) or two-hand your weapon to break through the miner enemies easily.

Guaranteed Overworld Pickups

If you prefer looting corpses and clearing out key regions, focus on these mid-to-late-game areas:

• Leyndell, Royal Capital: Search the outer courtyards, rooftops, and lower sewer walkways. Multiple corpses hold single and bundled Smithing Stones [6].
• Mt. Gelmir & Volcano Manor: Search the craggy cliffs leading up to Volcano Manor and the lava pools inside the manor complex.
• Subterranean Shunning-Grounds: Check the dark tunnels beneath Leyndell for drops on corpses near the Omen enemies.

How to Unlock Unlimited Smithing Stone [6]

To purchase infinite Smithing Stone [6], you need to locate the Smithing-Stone Miner’s Bell Bearing [3].

1. Travel to Mountaintops of the Giants
2. Locate the Zamor Ruins (near the Grand Lift of Rold)
3. Enter the underground stairwell in the ruins
4. Open the chest to retrieve Smithing-Stone Miner's Bell Bearing [3]
5. Hand the Bell Bearing to the Twin Maiden Husks at Roundtable Hold

Once unlocked, the Twin Maiden Husks will sell Smithing Stone [5] and [6] infinitely for 6,000 Runes each.
