Looking for the Sword Of Light in Elden Ring: Shadow Of The Erdtree? With the addition of the Shadow Of The Erdtree expansion, From Software's gargantuan Elden Ring now has over 400 weapons to choose from. Truly a mind-boggling arsenal. But the Sword Of Light and its sister sword, the Sword Of Darkness, are unique even among unique weapons, because they are twins that transform into one another at will. And both are first transformed from a third weapon, the Stone-Sheathed Sword.

It's a confusing little puzzle which requires you to seek out the three Altars Of Light And Dark strewn about the Land Of Shadow. In this guide, we'll break it all down so you can easily find the Stone-Sheathed Sword, and understand where to go in order to transform it into the powerful Sword Of Light and Sword Of Darkness weapons.

In this guide:

Where to find Stone-Sheathed Sword (All Altar locations)

Before you can get either the Sword Of Light or the Sword Of Darkness in Elden Ring, you first need the Stone-Sheathed Sword. There are three possible locations where the Stone-Sheathed Sword can appear, and it will always appear at the first location you look.

To get the Stone-Sheathed Sword, you need to visit one of the following three Altar locations:

  1. Inside the Fog Rift Catacombs in the Gravesite Plain.
  2. Inside the Ruins Of Unte in Scadu Altus.
  3. At the end of the invisible bridge in the Ancient Ruins Of Rauh.

1. Fog Rift Catacombs Altar location

The easiest Altar to reach at the start of the DLC is in the Fog Rift Catacombs. To reach these Catacombs, cross the Ensis Greatbridge and then follow the path northwest from the Castle Front Site Of Grace. At the far north end of the path is the entrance to the Fog Rift Catacombs.

Inside the Catacombs, follow the path until you reach a long room with three sets of spike traps descending from the ceiling. Proceed to the platform at the end of the room where the mage is standing, then stand on the very edge to bait the traps into descending again. When they come down, you'll see a little cubbyhole you can jump into, which transports you up to a higher platform when the trap ascends back up to the ceiling.

Jump off onto this ledge (and pick up the Blinkbolt Ash Of War while you're here), then turn around and perform the same baiting trick to jump on top of the spike platform. Once you're on top, run over to the far right corner of the room, and you'll see a final platform that you can jump down into once the spike traps have ascended back to the ceiling. Inside this secret area is an Altar Of Light And Dark which you can loot to obtain the Stone-Sheathed Sword.

2. Ruins Of Unte Altar location

The second Altar where you can loot the Stone-Sheathed Sword is located inside the Ruins Of Unte in Scadu Altus. To reach the Ruins Of Unte, you need to pass through the main gate of the Shadow Keep, beyond the Golden Hippopotamus boss. Once you're on the ramparts outside, stop at the bottom of the stairs guarded by the Fire Knight which lead up to the Specimen Storehouse.

Near to this staircase, next to the boats guarded by Vulgar Militiamen, there is a ladder that leads down to a small waterfall. Pass through the waterfall and follow the path, and you'll end up in a room with the "Domain Of Dragons" Painting.

Hit the wall on your right in this room, and another secret passage will be revealed. This passage leads you to a stone coffin that you can interact with to get inside and transport your character to the Castle Watering Hole in Scadu Altus below the Shadow Keep. Right in front of the Castle Watering Hole Site Of Grace, you'll find the Ruins Of Unte.

To get inside the Ruins Of Unte, lob a Hefty Furnace Pot inside the basket of the dead Furnace Golem blocking the entrance. Inside the Ruins and slightly to the right, you'll find an Altar Of Light And Dark where you can obtain the Stone-Sheathed Sword.

3. Ancient Ruins Of Rauh Altar location

The final location of an Altar where you can get the Stone-Sheathed Sword is located in the Ancient Ruins Of Rauh, a sub-region of Rauh Base which you can only access via the Shadow Keep. To reach it, you'll need to head through the Living Jar area beneath the Specimen Storehouse, and use the long bridge heading west out of the Shadow Keep to reach the Ancient Ruins Of Rauh.

After that, progress through the ruins and beyond the Furnace Golem to reach the "Rauh Ancient Ruins, West" Site Of Grace. From here, head southwest into the nearby ruins and go up the stairs. Exit into the garden to the north, and cross the garden to enter the rotted area of the ruins, guarded by Kindred Of Rot.

Head straight forward through the rot area, then turn right, and head straight on again, out into the outdoor ledge. You'll see at your feet one end of a broken bridge, and in the distance, the other end of the bridge connects to a tower. As it turns out, the bridge isn't broken; it's just invisible. Ride straight across it and you'll reach the third and final Altar Of Light And Dark where you can find the Stone-Sheathed Sword.


How to get the Sword Of Light

Once you have the Stone-Sheathed Sword, you can transform it into the Sword Of Light, a much more powerful unique version of the sword with a powerful and unique area-of-effect Holy damage skill simply called "Light".

To get the Sword Of Light, you must take the Stone-Sheathed Sword to an unused Altar Of Light And Dark, and interact with the Altar. You cannot use the Altar where you first found the Stone-Sheathed Sword; you need to use one of the other two Altars. So if you found the Stone-Sheathed Sword in the Fog Rift Catacombs, you can only get the Sword Of Light from the Ruins Of Unte or the Ancient Ruins Of Rauh.

Once you've found an unused Altar Of Light And Dark, walk up to it and interact with it while the Stone-Sheathed Sword is in your possession. You'll get a prompt that reads: "Raise the Stone-Sheathed Sword to the light?". Click "YES", and the Stone-Sheathed Sword will transform into the Sword Of Light.


How to get the Sword Of Darkness

You might think that the Sword Of Light is the Stone-Sheathed Sword's final form, but there is in fact one more form after that: the Sword Of Darkness. The Sword Of Darkness is very similar to the Sword Of Light, with the same scaling, attacks, and Holy Damage. Where it differs is its unique skill, "Darkness", which spews forth clouds of damage-dealing darkness as opposed to rays of holy damage conjured by "Light".

To get the Sword Of Darkness, you must take the Sword Of Light to the final unused Altar Of Light And Dark in the Land Of Shadow. To recap, the three Altar locations are:

  • In the Fog Rift Catacombs.
  • In the Ruins Of Unte.
  • In the Ancient Ruins Of Rauh.

You will already have used two of these Altars to unlock the Sword Of Light. To get the Sword Of Darkness, find the final Altar and interact with it to "Raise the Sword Of Light to the dark", transforming it into the Sword Of Darkness.

Afterwards, you can change the Sword Of Darkness back into the Sword Of Light at any time, simply by revisiting the Altar that you used to get the Sword Of Light in the first place. You can also change the Sword Of Light back into the Sword Of Darkness at any time by interacting with the final Altar again. This way, you can keep switching between the two powerful versions of the sword to best fit your needs.

That concludes this guide on the Stone-Sheathed Sword, the Sword Of Light, and the Sword Of Darkness in Elden Ring: Shadow Of The Erdtree.
