Stillblade’s Stone is a Combat Tarstone looted from a chest inside the Citadel Annex beacon in the Faded Citadel, and it gives your Primary Weapon a special light combo finisher that deals Break Damage.
Tarstones are how you bolt extra behavior onto your gear in Mortal Shell 2, and Stillblade’s Stone is one of the cleaner Break-focused picks for a melee build. It slots into a Primary Weapon and rewards you for finishing your light strings, which makes it a natural fit if you like cracking an enemy’s poise open before you commit to the big hit. The catch is that it lives inside a short beacon dungeon that’s very easy to leave without the reward.
What Stillblade’s Stone is and which slot it uses
| Detail | Value |
|---|---|
| Type | Combat |
| Compatible | Primary Weapon |
| Effect | Special Light Combo Finisher that deals Break Damage |
| Location | Citadel Annex beacon, Faded Citadel |
This is a Combat-type Tarstone, so it goes on your melee Primary Weapon rather than a sidearm. Its whole identity is the unique Light Combo Finisher it unlocks, and that finisher deals Break Damage — meaning it’s built to feed stagger rather than raw health damage. If your build already leans on breaking guard and cashing in on staggered enemies, it fits straight in; if you’re a pure sidearm or Resolve-tool player, it does nothing for you.
How to get the Stillblade Stone in Mortal Shell 2
Reach the Citadel Annex beacon

Choose Cleanse Beacon
Choose Cleanse Beacon | FightinCowboy/YouTubeSelect Cleanse Beacon to drop into the Hushed Sanctum combat run.
Ride the spider-like creature
Ride the spider-like creature | FightinCowboy/YouTubeFollow the linear path and ride the spider-like creature across the gap partway through.
Defeat the enemy right after
Kill the enemy waiting on the far side to expose the chest.
Loot the chest first
Loot the chest first | FightinCowboy/YouTubeOpen the chest to claim your Level 1 Stillblade’s Stone before you touch the core.
Cleanse the corrupted core
Only now interact with the corrupted crystal core to finish cleansing the beacon and leave.
The dungeon is short, which is exactly why so many players walk out empty-handed — it’s tempting to sprint to the core, cleanse it, and warp away. Do that and you forfeit the stone entirely, forcing a full rerun of the beacon to get another shot at the chest.
Open the chest before you cleanse the corrupted core. Cleansing first and leaving skips the stone and means running the whole beacon again.
What the finisher does and its Break Damage by level
| Level | Break Damage |
|---|---|
| Lv. 1 | 10 |
| Lv. 2 | 15 |
| Lv. 3 | 25 |
Equipped, Stillblade’s Stone extends your light attack string into a dedicated finisher that lands as pure Break Damage, so every completed combo chips away at an enemy’s poise instead of just their health. That makes it a strong engine for stagger-focused melee play, where you’re looking to break guard and then punish, and it slots naturally alongside speed-and-stack picks like Thief’s Stone or a resolve-oriented option like Zealot’s Stone depending on how you build. The Break contribution grows as you level the stone:
An older listing tiers those numbers across different levels, but the 10 / 15 / 25 ladder above is the current post-patch scaling and the one to plan around.
Key A common misread is expecting the stone to level up passively as you play — it won’t. Each Tarstone earns its own experience only while it’s equipped, and it stays parked at Level 1 until you fill that bar and pay Franz. None of this is needed just to add the stone to your collection, so you can grab it now and upgrade later once the Tarforge is unlocked.

Frequently Asked Questions
Do you have to upgrade Stillblade’s Stone for the Stoned trophy?
No. Upgrading only raises the finisher’s Break Damage — it has nothing to do with the Stoned trophy and achievement, which asks you to obtain Tarstones rather than level them. You only need to collect the game’s Tarstones rather than upgrade them, so simply looting Stillblade’s Stone from the Citadel Annex chest is enough to count it toward that total.
