Cut Lass Location in Grounded 2: Into the Abyss

The Cut Lass is a hidden Masked Stranger sword added in the Into the Abyss update for Grounded 2. It sits at the back of a flooded cave system beneath the sour water pond in the Pergola region, guarded by a poison-heavy swim and one tough scorpion. Reaching it also unlocks a matching recipe at a Forbidden Workbench.

Quick answer: Take a Tier 3 Omni-Clipper and a Tier 3 Omni-Axe to the sour (tang) pond in the Pergola area, dive in and follow the tunnel marked with the purple Masked Stranger symbol, clip the Soggy Roots and Pond Moss blocking the damaged pipe, surface into the cave, kill the O.R.C. Striped Bark Scorpion, then chop the Gloom Shrooms at the back to reveal the Cut Lass.

Gear and mutations to bring

The route punishes two things above all else: bad swim gear and no cutting tools. A Tier 3 Omni-Clipper is mandatory because roots and moss block the only path forward, and a Tier 3 Omni-Axe is what finally opens the chamber. Pack tang resistance and healing before you go, since the sour water drains health quickly.

Item	Why you need it
Tier 3 Omni-Clipper	Cuts the Soggy Roots and Pond Moss blocking the underwater pipe
Tier 3 Omni-Axe	Chops the Gloom Shrooms hiding the final chamber
Koi Scale Greaves (swim speed)	Faster movement through the flooded tunnels
Merteen mutation	Swim speed, longer breath, and water chill reduction
Sour Sensation mutation	Tang reduction and protection inside the sour pond
Healing smoothies / Chrysalis Bandages	Recovers health lost to tang and the scorpion fight
EverChar Torch	Lights the dark tunnels so you can spot the path
Diving gear (optional)	Alternative oxygen source if you are short on swim mutations

Note: The tang water degrades armor durability. Many players strip their armor off before diving to protect it, then re-equip everything the moment they leave the water and before the scorpion fight. If you would rather stay armored, tang-resistant gear such as Rust Beetle armor keeps durability loss down.

How to reach the Cut Lass

Travel to the Pergola area and find the large green sour pond tucked near the Pumpkin Patch wall. This is a pool of tang, not clean water, so treat it as a hazard from the moment you approach.

Remove your armor if you want to avoid durability loss, keep Sour Sensation active, and dive in. Follow the pond down to the bottom to find the submerged tunnel entrance.

Swim down into the cavern and watch for a rock marked with the purple Masked Stranger logo. Keep an eye on your oxygen meter and use a torch or lantern to spot the glowing purple Raw Science ahead, which marks the damaged pipe you need.

Use the Tier 3 Omni-Clipper to cut the Soggy Roots blocking the pipe, then swim into it. There is a small air pocket at the top of the pipe where you can surface and refill oxygen before continuing.

Dive down again and clear the second set of Soggy Roots and the Pond Moss with the clipper. Follow the poly pipe out of the liquid until you surface into a dry rocky tunnel.

Re-equip your armor now that you are out of the tang. Enter the cave and fight the O.R.C. Striped Bark Scorpion guarding it, watching for the laser attack that fires from its tail. Keep healing items ready during the trade.

Head to the cluster of Gloom Shrooms at the back of the cave and chop them down with the Tier 3 Omni-Axe. They drop Gloom Chunks and Gloom Sap worth grabbing, and clearing them opens the hidden chamber behind.

Enter the final chamber lit by glowing mushrooms and pick up the Cut Lass from the rock in the center. Collecting it confirms the pickup and unlocks its crafting recipe.

What the Cut Lass does

The Cut Lass is a Tier 4 slashing sword and a Masked Stranger variant of the Toenail Cutlass. Its signature effect is Infection, which slows an enemy’s attack speed and lowers their attack damage. Level it to four on the mighty path to gain Perfect Slash, which raises crit hit chance on perfectly charged sword attacks. That makes it a strong pick for fast, DPS-focused sword play and it pairs well with Toe Biter armor.

Crafting at the Forbidden Workbench

Retrieving the Cut Lass unlocks the Toenail Cutlass recipe, and Masked Stranger weapons like this are built only at a Forbidden Workbench, not a standard crafting bench. You cannot build these workbenches yourself; they appear in certain Ranger outposts. Pine Hill is the reliable spot to remember first, with the Ceremony area as a possible second location.

Material	Quantity
Toenail Cutlass	1
Hyper Beam	1
Gold Foil	2

Once the Cut Lass is in your backpack and the recipe shows up at a Forbidden Workbench, you know the run worked. From there you can enhance the weapon along the mighty path to reach Perfect Slash, and the Gloom Chunks you collected on the way out feed into other Abyss crafting, so hold onto them rather than dropping them at the cave.
