Mortal Shell 2 Thief’s Stone Location & Warp Attack Speed Effect
This article explains where to find the Thief’s Stone in Mortal Shell 2 and exactly how its warp attack speed effect works. You’ll get the precise location, the mechanics of the warp attack speed bonus, and practical tips for using it effectively.
Background: The Thief’s Stone in Mortal Shell 2
The Thief’s Stone is a special item in Mortal Shell 2 that modifies your character’s abilities, specifically enhancing the speed of warp attacks. Warp attacks are a unique mechanic in the game where you teleport short distances to strike enemies, often bypassing shields or closing gaps quickly. The Thief’s Stone is one of several ‘Stones’ that players can equip to alter their playstyle, and its primary appeal is the aggressive, high-speed approach it enables.
Unlike other stones that might boost raw damage or defense, the Thief’s Stone focuses on mobility and attack frequency. This makes it a favorite for players who prefer a hit-and-run style or who want to exploit enemy weaknesses with rapid, unpredictable strikes. Understanding where to find it and how its speed boost actually works is key to integrating it into your build.
Exact Location of the Thief’s Stone
The Thief’s Stone is located in the Fallgrimm Outskirts, specifically within the Underground Grotto area. To reach it, you must first progress through the main story until you gain access to the Grotto, which is typically after defeating the first major boss, Grisha, and obtaining the ability to interact with the large, glowing pillars.
Once inside the Grotto, follow these steps:
- From the Grotto’s entrance, head towards the easternmost tunnel, which leads to a large, open cavern filled with toxic pools.
- Navigate carefully across the platforms above the toxic water, avoiding the poison damage and the lurking enemies (typically Grisha variants and Gutter Zombies).
- At the far end of the cavern, you will see a small alcove partially hidden behind a broken pillar. The Thief’s Stone is on a pedestal inside this alcove.
- Interact with the pedestal to claim the stone. Note that there are no traps or enemies guarding it directly, but the journey through the toxic area is the main challenge.
If you have already cleared the area, the stone will still be there, as it is a fixed item that does not respawn or disappear.
How the Warp Attack Speed Effect Works
The Thief’s Stone’s primary effect is a 15% increase to warp attack speed. This means that when you perform a warp attack (by dodging into an enemy and pressing the attack button), the entire animation—including the teleport, the strike, and the recovery—is completed 15% faster than without the stone.
This speed increase is multiplicative, not additive. So if your base warp attack takes 1.0 second, with the Thief’s Stone it takes 0.85 seconds. This reduction applies to all warp attacks, regardless of weapon type, and it stacks with other speed-increasing effects, such as those from certain weapons or consumables.
It’s important to note that the stone does not affect normal attack speed, dodge speed, or movement speed. Its effect is exclusively on the warp attack animation. This makes it ideal for builds that rely heavily on warp attacks as a primary damage source.
Choosing the Right Stone for Your Build
While the Thief’s Stone is excellent for aggressive play, it’s not always the best choice. Here’s how it compares to other common stones:
- Thief’s Stone – Best for players who use warp attacks frequently and want to maximize DPS through speed. It shines with fast weapons like the Hammer and Chisel, where the speed boost allows for multiple warp strikes in quick succession.
- Warrior’s Stone – Increases physical damage by 10%. Better for players who rely on normal attacks and heavy weapons, where a flat damage boost outweighs the speed benefit.
- Mage’s Stone – Boosts resolve gain, which is useful for players who frequently use special abilities. Not directly comparable to the Thief’s Stone, but it’s a good alternative if you prefer a more balanced approach.
When choosing, consider your weapon’s moveset and your personal playstyle. If you find yourself using warp attacks often (for example, to close gaps or to break enemy poise), the Thief’s Stone is a strong pick. If you prefer a more defensive or methodical approach, other stones may serve you better.
Common Mistakes and Misconceptions
One common misconception is that the Thief’s Stone increases all attack speeds. As mentioned, it only affects warp attacks. Players who equip it and expect faster normal swings will be disappointed. Another mistake is assuming the speed boost is additive with other speed modifiers, leading to unrealistic expectations. The multiplicative nature means the actual reduction is slightly less than the sum of individual percentages.
Also, some players believe the stone makes you invulnerable during the warp attack. It does not. While the warp animation has i-frames (invincibility frames) for a brief moment, the speed increase does not extend them. You can still be hit if you time the attack poorly, especially against enemies with wide sweeps.
Tips for Maximizing the Thief’s Stone Effect
To get the most out of the Thief’s Stone, consider these strategies:
- Pair with fast weapons – Weapons like the Hammer and Chisel or the Martyr’s Blade (when upgraded) have quick warp attacks that benefit disproportionately from the speed boost.
- Use the ‘Lunge’ attack – The lunge (dodge + heavy attack) is also considered a warp attack and gets the speed bonus. This is great for closing distance and staggering enemies.
- Combine with stamina regen items – Since you’ll be attacking more frequently, you’ll consume stamina faster. Equip items or use abilities that boost stamina regeneration to sustain your aggression.
- Practice timing – The faster animation can throw off your rhythm. Spend time in the training area to get used to the new timing, especially for parries and dodges that follow a warp attack.
Frequently Asked Questions
Is the Thief’s Stone worth it compared to other stones?
It depends on your build. If you rely on warp attacks, yes. If you use mostly normal attacks, a damage-boosting stone like the Warrior’s Stone is more effective. Consider your weapon and playstyle before equipping it.
Does the Thief’s Stone affect dodge speed?
No, it only affects warp attack speed. Dodging and movement speed are unchanged. This means you won’t become more evasive, only more aggressive in your attacks.
Can I get the Thief’s Stone early in the game?
Yes, you can reach the Fallgrimm Outskirts and the Underground Grotto relatively early, right after defeating the first boss. However, the toxic pools and enemies can be challenging at low levels, so it’s advisable to have a few upgrades first.
Does the speed increase stack with other items?
Yes, it stacks multiplicatively with other speed-increasing effects, such as those from certain consumables or weapon abilities. The total reduction is calculated by multiplying the individual modifiers together.
Is there a downside to using the Thief’s Stone?
The main downside is that it occupies a stone slot that could be used for other bonuses, like damage or defense. Additionally, the faster attack speed can lead to stamina management issues if you’re not careful.
