Mortal Shell 2 Squall Stone Location, Effects, and Sidearm Uses

The item is spelled Squall Stone, not “Squail Stone.” It is a projectile-focused Combat Tarstone found deep inside the sewer dungeon unlocked by the Executioner’s Pulpit Beacon. Follow the route below to reach its chest, then socket it into a compatible sidearm to make landed projectiles spin and continue dealing damage.

How to get Squall Stone in Mortal Shell 2

Cleanse the Executioner’s Pulpit Beacon

Go to the beacon in Prisoners’ Domain near the Tishina’s Confessor fight and cleanse it. This opens the linked Central Sewers below.

Take the elevator down

Ride the elevator beside the beacon down into the Central Sewers. The dungeon opens into a sprawling labyrinth of tunnels.

Push straight ahead through the sewers

Stay on the main path, smash the barriers blocking the route, and clear the enemies waiting in the corridors. Pick up the loot as you move forward.

Work the gate-and-lever rooms

Shoot the target to raise the first gate. Continue through the following rooms and pull each lever to open the next door.

Clear the challenge room

Defeat the tough enemy gauntlet, then press the buttons in the room to reveal the path leading to the chest.

Open the chest in the side chamber

What the Squall Stone does to your sidearm shots

Socket the Squall Stone into a compatible sidearm to make its projectiles spin in place after they hit their target. Instead of landing once and disappearing, each shot lingers for a short window and deals a portion of its original damage. This creates sustained pressure and pairs especially well with sidearms that can put more shots onto one target. The effect improves with each level:

The progression is 3s/8% → 4s/9% → 5s/10%. Rank listings differ on whether the stone ends at three levels or includes a fourth tier. Before spending upgrade materials, check the stone’s compatibility list: the Squall Stone works only with specific Sidearms, not every ranged tool.

Mistakes players make hunting the Squall Stone

The biggest time-sink is searching for “Squail Stone.” The correct name is Squall Stone; no item exists under the misspelled name. Another common mistake is stopping at the surface after cleansing the beacon. The chest is deep inside the Central Sewers dungeon opened by the beacon, not on the platform.

The stone also does not buff melee attacks or every ranged tool; it modifies only its compatible Sidearms. If your stone stops leveling where a guide suggests another rank, it is not bugged—the discrepancy comes from mismatched three-rank and four-rank documentation, not a broken upgrade.

Projectile Tarstones worth grabbing after this

After collecting the Squall Stone, grab the other projectile-focused options: the Splitting Stone and the Myriad Stone. They change the number of projectiles you fire and how those projectiles spread, stacking neatly with Squall Stone’s lingering spin to land more total hits on a target.

Tarforge and Gloom upgrade costs for Combat Tarstones changed in post-launch balance patches, so older prices quoted for leveling the Squall Stone are out of date. Check the current cost in your own Tarforge before planning your upgrades.
