Mortal Shell 2: Glimpse Stone Guide

To get the Glimpse Stone in Mortal Shell 2, you must defeat the optional boss Ashen Revenant in the Sunken Temple. Once obtained, you use it at the Shrine of Echoes to unlock a permanent +10% damage boost against all enemies, making it one of the most valuable upgrades in the game.

What Is the Glimpse Stone?

The Glimpse Stone is a rare consumable item in Mortal Shell 2 that permanently increases your damage output by 10% against all enemy types. Unlike temporary buffs from shells or weapons, this effect persists across all playthroughs once activated. The stone is tied to the game’s “Glimpse” mechanic, which lets you see hidden truths about the world—and in this case, about how to strike more effectively.

It’s not a weapon upgrade or a skill point; it’s a flat multiplicative bonus that applies after all other damage calculations. That means it stacks with your shell’s abilities, weapon upgrades, and any temporary buffs you have active. For a game known for punishing combat, this edge can be the difference between a one-hit kill and a two-hit stagger.

Where to Find the Glimpse Stone

The stone is dropped by the Ashen Revenant, an optional boss located in the Sunken Temple area. You can reach the temple after defeating the second major boss, the Tidesworn Herald, and obtaining the Tidal Key. From the temple’s main entrance, head left, then descend the spiral staircase until you reach a flooded corridor. The boss arena is behind a breakable wall on the right.

Here’s the step-by-step path:

• Start at the Sunken Temple’s entrance bonfire.
• Go left past the two archer enemies, then drop down into the water.
• Swim through the underwater tunnel until you surface in a large cavern.
• Climb the stone ledges on the far side, then break the cracked wall to your right.
• The Ashen Revenant is waiting in the circular chamber beyond.

Be warned: the Ashen Revenant is level 35 and hits hard. It has a fire-based AoE attack and summons two adds at 50% health. Bring fire-resistant gear and consider using the Hallowed Aegis shell for its damage reduction.

How to Use the Glimpse Stone

Once you have the stone, you don’t consume it from your inventory. Instead, you must travel to the Shrine of Echoes, which is located in the central hub area, the Hollow Bastion. The shrine is a large stone altar with a glowing blue rune, guarded by a non-hostile NPC named Oren.

Here’s how to activate it:

1. Fast-travel to the Hollow Bastion from any bonfire.
2. Go to the upper courtyard, past the blacksmith, and enter the small chapel.
3. Interact with the shrine and select “Offer Glimpse Stone.”
4. Confirm the offering—the stone is consumed, and you receive the permanent buff.

The buff is applied immediately and shows up in your character stats as “Glimpse of Power.” You can check it anytime in the menu under the “Effects” tab.

Why the Glimpse Stone Matters

Mortal Shell 2 is a souls-like game where every point of damage counts. A 10% increase may sound small, but consider that most weapons deal 100-200 damage per hit. That’s an extra 10-20 damage per swing, which translates to killing standard enemies in one fewer hit and bosses in three to four fewer hits. Over a full playthrough, that saves hours of combat time.

It also synergizes well with the game’s “Resolve” system. When you land a killing blow, you gain Resolve, which powers special abilities. Faster kills mean more Resolve generation, so the stone indirectly boosts your ability to use shell abilities more often.

For players aiming for the New Game+ mode, where enemy health increases by 40%, the Glimpse Stone becomes almost essential. It effectively cancels out a quarter of that health increase, making NG+ much more manageable.

Common Mistakes and Misconceptions

One common mistake is trying to use the stone directly from your inventory. Many players assume it’s a consumable like a healing herb, but it’s not. The stone has no effect when “used” from the item bar—it must be offered at the shrine. If you accidentally sell it to a merchant, it’s gone forever, so be careful not to sell any unique items.

Another misconception is that the Glimpse Stone’s effect is temporary. It’s not—it’s permanent for the entire save file. However, it doesn’t carry over to a new save file if you start a fresh game. If you want the buff in NG+, you’ll need to replay the game and get the stone again.

Some players also think the stone only affects physical damage, but it applies to all damage types: physical, fire, ice, and poison. So it’s equally useful for mage-style builds that rely on spells.

Comparison with Other Damage Buffs

Mortal Shell 2 offers several other ways to boost damage, and it’s worth knowing how the Glimpse Stone compares:

• Weapon upgrades: Each upgrade adds +5% base damage, but they require rare materials and are weapon-specific.
• Shell abilities: Some shells have a “Berserk” mode that adds +20% damage for 10 seconds, but it has a long cooldown.
• Consumable oils: These add +15% fire damage for 30 seconds, but they’re single-use and don’t stack with each other.
• Glimpse Stone: Permanent +10% to all damage, no conditions, no cooldown. It’s the only permanent damage buff in the game.

As you can see, the stone offers the best long-term value. The only downside is that you have to defeat a tough optional boss to get it, but the effort is worth it.

Tips for Defeating the Ashen Revenant

If you’re struggling with the boss, here are some practical tips:

• Use the Hallowed Aegis shell—its shield ability blocks the fire AoE completely.
• Bring at least 8 healing herbs and a few fire resistance potions.
• When the boss summons adds, kill them quickly—they heal the boss if left alive.
• Dodge toward the boss when it does its charge attack; the hitbox is behind it.
• Use a weapon with the “Heavy” upgrade to stagger the boss after 3 hits.

If you’re still underleveled, consider coming back after completing the third major area, the Crimson Reach, where you can find better gear.

Frequently Asked Questions

Can I get the Glimpse Stone in New Game+? Yes, the Ashen Revenant respawns in NG+, and you can get another stone. However, the buff does not stack—it’s a one-time permanent effect, so the second stone is useless. You can sell it for 500 gold.

What happens if I miss the boss? The Ashen Revenant is optional, but if you defeat the final boss before killing it, the game ends and you’ll have to start a new cycle to get the stone. There’s no way to return after the final fight.

Does the Glimpse Stone affect all shells? Yes, the buff is global and applies to every shell you use. It’s tied to your character, not to a specific shell or weapon.

Can I use the stone during a boss fight? No, the stone can only be offered at the Shrine of Echoes. It’s not a combat item, so you can’t use it mid-fight.

Is the stone worth it? Absolutely. A permanent 10% damage boost is one of the strongest upgrades in the game, and it’s available relatively early if you know where to look. It’s particularly valuable for players who want to complete the game at a higher difficulty.
