The Blood of Dawnwalker: Large Lizard’s Moult Location in Briar Sloughs

The Large Lizard’s Moult is one of four components you need for the Arbiter’s Armour set in A Bulwark Against Darkness. Unlike the other three, it isn’t tied to a quest chain, a merchant, or a boss fight. It sits on the floor of a cave that never appears on your map, in the marshy stretch between Briar Sloughs and Marasg Wealds, and the only way to get it is to walk there.

Quick answer: Travel to the marshland southwest of Marasg Wealds, in the Briar Sloughs region south of the witchcraft vendor. Squeeze through the narrow crack in the rock face, follow the single path inside, and interact with the yellow shed skin to trigger “Pick Up Large Lizard’s Moult.”

Where the cave entrance is in Briar Sloughs

The cave straddles the border between Briar Sloughs and Marasg Wealds, in Vale Sangora. There is no icon for it, no quest marker pointing at it, and no fast-travel point right on top of it. You are looking for a gap in a rock wall surrounded by swamp, with heavy slime trails smeared on the ground leading toward the opening.

Three separate landmarks put you on it, so use whichever you have already unlocked.

Landmark	Direction to the cave
Marasg Wealds	Head southwest into the marshland
Muddy Trail Shrine	Head due east until slime trails appear
Witchcraft vendor (Vera)	Head directly south

Open the map and set your own marker before you set off. The area is flat, wet, and visually repetitive, and it is easy to overshoot the rock face if you are running on the compass alone.

How to get the Large Lizard’s Moult

Ride or run to the marsh between the two regions and look along the rock faces at ground level. The entrance is a vertical crack, not an arch, and it reads as scenery until you are close enough for the interaction prompt to appear.

Squeeze through the gap. Your character will push sideways through the narrow section, which is the confirmation that you found the right spot rather than a decorative rock formation.

Follow the path forward. The interior is dark and linear, with no branching routes or puzzles, so you cannot take a wrong turn. Clear any enemies that block the way as you go.

Continue to the far side of the cave. The moult is a large, pale yellow sheet of shed skin lying on the cave floor at the end of the route, and it stands out clearly against the dark stone.

Interact when the “Pick Up Large Lizard’s Moult” prompt appears. That single interaction is the whole objective. There is no timer, no follow-up fight, and nothing else to collect in the cave.

How to confirm the moult registered

Two things happen the moment you pick it up. The “Find the moult of a large lizard” objective ticks off in your quest log, and you get a “NEW RECIPE UNLOCKED” banner for Fortitude Paste. If you see the recipe banner, the item is yours.

You can also verify it directly. The Large Lizard’s Moult sits in your inventory as a Quest-tier item with an orange background, alongside the other Arbiter components. Its description reads, “It wasn’t easy to kill its previous owner.”

Note: You do not need to have started A Bulwark Against Darkness to grab the moult. The item exists in the world from the beginning, so picking it up early is safe and the objective will already be satisfied when the quest arrives.

Common reasons you can’t find the cave

Almost every failed attempt comes down to the same handful of mistakes.

Waiting for a map icon. The cave is unmarked, so no marker will ever appear over the entrance.
Searching too far north. The location is southwest of Marasg Wealds and south of the witchcraft vendor, not inside the Wealds proper.
Looking for a wide cave mouth. The way in is a narrow crack you squeeze through, close to ground level.
Turning back too early. The moult is on the opposite side of the cave, not near the entrance.

With the moult in hand, only the relic of a saint, the bundle of silk threads, and the flask of quicksilver stand between you and the trip to the uriashi blacksmith. Of the four, this is the one you can clear in a couple of minutes at almost any point in a playthrough, so it is worth detouring for the moment you are anywhere near the Briar Sloughs.
