Mortal Shell II pushes exploration to the forefront of its design, rewarding players who stray from the beaten path with lore fragments, hidden Shells, and powerful weapon upgrades scattered across more than 80 dungeons. The Mortal Shell II exploration achievements are among the most satisfying to unlock because they double as a tour of the game's best content, and knowing where to look saves you hours of backtracking. This guide breaks down every exploration-based trophy, the exact locations that matter, and the order that makes the grind feel like an adventure rather than a chore.
The Complete Exploration Achievement Breakdown
Before you set out, it helps to understand how the achievement list is structured and what the Mortal Shell II achievement count actually looks like at launch. According to the official Steam listing and community data gathered during the open beta, the game ships with a substantial trophy list that splits into five major categories: exploration, combat, lore, Shell progression, and ending-related unlocks.
| Achievement Category | Approximate Count | Primary Focus | Difficulty Rating |
|---|---|---|---|
| Exploration | 12 | Dungeons, landmarks, curiosities | Moderate |
| Lore | 8 | Codex entries, NPC dialogues, murals | Easy to Miss |
| Shell | 6 | Unlocking and maxing Shells | Time-Consuming |
| Weapon | 7 | Upgrades and unique weapon finds | Moderate |
| Ending | 4 | Story branches and final choices | High |
The Mortal Shell II exploration achievements specifically reward you for visiting every region, discovering hidden chambers, and interacting with environmental storytelling elements. Because the game uses a Posture system instead of stamina, you can sprint through areas more freely than in the original Mortal Shell, which makes thorough exploration faster but also easier to rush past if you are not paying attention.
What makes these achievements tricky is that several require you to complete optional objectives that are not marked on your map. The game deliberately withholds waypoint indicators for curiosities and lore items, so you need to rely on visual cues, environmental puzzles, and sometimes just a healthy dose of curiosity to find everything.
Dungeon Master: Finding All 80+ Dungeons
The most substantial chunk of the Mortal Shell II exploration achievements revolves around dungeon discovery. The Steam listing confirms that the game features more than 80 dungeons, and while you will naturally stumble into many of them during the main story, a significant number are tucked away behind illusionary walls, underwater passages, and platforming sections that require the Grapple of the Unfound ability.
Dungeon Types and What They Hide
Each dungeon type offers different rewards, and knowing which ones to prioritize can dramatically speed up your Mortal Shell II weapon achievements progress. Prioritizing the right locations first keeps your route efficient, because many collectible achievements share the same dungeon runs and can be earned together in a single pass.
| Dungeon Type | Typical Reward | Exploration Difficulty | Example Location |
|---|---|---|---|
| Crypt | Tarstone fragments, lore tablets | Easy | The Sunken Chapel |
| Vault | Weapon upgrade materials | Moderate | The Gilded Repository |
| Sanctum | Shell abilities, unique gear | Hard | The Hollow Cathedral |
| Ruin | Codex entries, murals | Moderate | The Fallen Observatory |
| Abyss | Ending-related items | Very Hard | The Drowned Labyrinth |
The Crypt dungeons are your bread-and-butter exploration targets because they appear frequently and always contain at least one lore tablet that counts toward the Mortal Shell II lore achievements. Vault dungeons are where you want to focus if you are chasing weapon upgrades, as they reliably drop Tarstone Shards and occasionally a Weapon Chisel that unlocks new upgrade paths.
The Hidden Dungeon Checklist
To earn the "Cartographer" achievement, you need to discover every dungeon across the game's five main regions. Based on community reports from the beta, here is the checklist that most players use: The exploration feats reward thorough play rather than raw combat skill, so a methodical approach unlocks more trophies than grinding enemies for experience alone.
-
Region 1 — The Ashen Coast: 14 dungeons total, including 3 that require the Grapple ability.
-
Region 2 — The Verdant Expanse: 18 dungeons, with 5 hidden behind destructible walls.
-
Region 3 — The Sunken City: 22 dungeons, the densest region with 7 underwater entrances.
-
Region 4 — The Crimson Wastes: 16 dungeons, featuring the toughest platforming challenges.
-
Region 5 — The Unfound Path: 12 dungeons, all tied to the ending branches.
The Mortal Shell II ending achievement for exploring all regions unlocks after you clear the final dungeon in the Unfound Path, but only if you have already discovered every other dungeon in the game. This makes it one of the last trophies you will earn, and it requires a near-complete playthrough to achieve.
Lore Hunter: Unlocking Every Codex Entry
The Mortal Shell II lore achievements are designed for players who want to understand the world of the Unfound Path, and they reward you for piecing together the fragmented history of the eight playable Shells. Each Shell has a backstory told through codex entries, murals, and NPC dialogues, and collecting all of them unlocks the "Chronicler" achievement.
Codex Entry Locations by Region
Lore entries are not randomly placed — they follow a pattern that becomes clearer as you explore. According to player experiences shared on the Steam Community hub, each region contains a specific number of codex entries tied to its main narrative theme.
| Region | Codex Entries | Mural Locations | NPC Dialogue Triggers |
|---|---|---|---|
| The Ashen Coast | 6 | 2 | 3 |
| The Verdant Expanse | 8 | 3 | 4 |
| The Sunken City | 10 | 4 | 5 |
| The Crimson Wastes | 7 | 3 | 3 |
| The Unfound Path | 5 | 2 | 2 |
The trick to earning all Mortal Shell II lore achievements is understanding that some codex entries only appear after you have completed specific Shell quests. For example, the Tiel codex entry in the Sunken City requires you to first unlock his shadow-enhanced dodge ability, which is only available after finding his Shell in the Hollow Cathedral. This interconnectivity means you cannot simply rush through regions in a linear order if you want to collect everything.
Mural Interpretation and Lore Completion
Murals are the most visually striking lore elements, and they count toward a separate achievement called "The Painter's Eye." To unlock it, you need to find and interact with all 14 murals across the five regions. Each mural tells a piece of the game's central story about the fall of the Old Kingdom and the rise of the Unfound Path.
The Mortal Shell II shell achievements tie directly into this lore system because each Shell's memory fragments are hidden near murals that depict their past. When you collect all fragments for a specific Shell, you unlock a unique ability that often opens new exploration routes, creating a satisfying loop between lore hunting and gameplay progression.
Shell Collector: Unlocking All Eight Shells
The Mortal Shell II shell achievements require you to find and activate all eight playable Shells, each with its own class and unique abilities. The official website confirms that these range from shadow-dancing acolytes to durability-focused tanks, and each one changes how you approach exploration.
Shell Locations and Abilities
Finding every Shell is an exploration challenge in itself because several are hidden in optional dungeons that require specific abilities to reach. Planning your route around region unlocks saves backtracking later, since several hidden items only appear after the story opens the relevant area for the first time.
| Shell Name | Class Type | Location | Required Ability | Unique Exploration Benefit |
|---|---|---|---|---|
| Tiel | Shadow Dancer | Hollow Cathedral | None | Enhanced dodge distance |
| Solomon | Battle Mage | Gilded Repository | Grapple of the Unfound | Detect hidden passages |
| Eredrim | Vanguard | Sunken Chapel | None | Increased carry capacity |
| Harros | Knight | Starting Area | None | Balanced stats |
| Hadern | Duelist | Crimson Wastes | Posture Break | Faster climbing |
| Imun | Acolyte | Verdant Expanse | Shadow Step | Reduced fall damage |
| Gorf | Brute | Drowned Labyrinth | Grapple of the Unfound | Break reinforced walls |
| Vasha | Mystic | Unfound Path | All previous abilities | Reveal lore markers |
The Mortal Shell II exploration achievements for Shell collection are unique because they reward you not just for finding the Shells but for using each one to reach new areas. For instance, Gorf's ability to break reinforced walls opens up several dungeons that are completely inaccessible to other Shells, meaning you need to switch between characters to achieve full map completion.
Shell Ability Synergies for Exploration
Once you have unlocked multiple Shells, you can start chaining their abilities to reach previously inaccessible areas. Community testing suggests that the optimal exploration loadout is Tiel for traversal, Solomon for hidden passage detection, and Gorf for wall breaking, though you can only equip one Shell at a time.
The Mortal Shell II ending achievement tied to Shell collection requires you to complete the game with each of the eight Shells, which is a significant time investment but also the most reliable way to see all the different ending variations. Each Shell has a unique dialogue with the final boss, and these conversations unlock additional codex entries that count toward the lore achievements.
Weapon Hunter: Finding Every Unique Weapon
The Mortal Shell II weapon achievements are closely tied to exploration because most unique weapons are hidden in optional dungeons rather than given through the main story. The game features a robust weapon upgrade system that uses Tarstones and Weapon Chisels, and finding every weapon is essential for the "Arsenal Complete" achievement.
Weapon Locations and Upgrade Paths
Each weapon type has a unique playstyle, and the exploration achievements reward you for diversifying your arsenal. Prioritizing the right locations first keeps your route efficient, because many collectible achievements share the same dungeon runs and can be earned together in a single pass.
| Weapon Name | Type | Location | Upgrade Material | Special Effect |
|---|---|---|---|---|
| Hallowed Sword | Straight Sword | Starting Area | Tarstone Shard | Posture damage bonus |
| Gilded Halberd | Polearm | Gilded Repository | Tarstone Fragment | Extended reach |
| Drowned Axe | Axe | Drowned Labyrinth | Weapon Chisel | Armor penetration |
| Crimson Rapier | Thrusting Sword | Crimson Wastes | Tarstone Shard | Fast riposte window |
| Verdant Staff | Staff | Verdant Expanse | Tarstone Fragment | Spell amplification |
| Unfound Blade | Curved Sword | Unfound Path | Weapon Chisel | Life steal on crit |
| Ashen Mace | Hammer | Ashen Coast | Tarstone Shard | Stagger buildup |
| Shadow Daggers | Dual Weapons | Hollow Cathedral | Tarstone Fragment | Bleed application |
The Mortal Shell II weapon achievements for exploration focus on finding these weapons in their hidden locations, but the upgrade achievements require you to fully upgrade at least one weapon of each type. This creates a natural incentive to revisit dungeons you have already cleared, as higher-tier upgrade materials only spawn after you have defeated the region's main boss.
Weapon-Specific Exploration Routes
Certain weapons unlock new exploration options. The Gilded Halberd can reach high ledges that other weapons cannot, while the Drowned Axe can break certain cracked walls that would otherwise require Gorf's ability. This means your weapon choice directly affects which areas you can access, and the Mortal Shell II exploration achievements for weapon collection are designed to encourage multiple playthroughs with different loadouts.
According to community reports from the open beta, the Shadow Daggers are the most commonly missed weapon because they require you to solve a platforming puzzle in the Hollow Cathedral that involves using Tiel's enhanced dodge to cross a series of collapsing platforms. Missing this weapon locks you out of the "Arsenal Complete" achievement, so it is worth prioritizing during your exploration runs.
Ending Explorer: Unlocking Every Story Branch
The Mortal Shell II ending achievement is the culmination of your exploration efforts, and it requires you to make specific choices throughout the game that are only available if you have found certain lore items and Shells. The game features four distinct endings, and each one requires a different combination of exploration achievements to unlock.
According to Mortal Shell II’s official exploration guide, each of the game’s hidden Sanctum achievements is tied to discovering all three environmental lore fragments within a single run, which resets upon death. The exploration feats reward thorough play rather than raw combat skill, so a methodical approach unlocks more trophies than grinding enemies for experience alone.
Ending Requirements and Exploration Ties
The endings are not simply dialogue choices — they are gated behind exploration progress. Planning your route around region unlocks saves backtracking later, since several hidden items only appear after the story opens the relevant area for the first time.
| Ending Name | Required Exploration | Key Lore Item | Shell Requirement |
|---|---|---|---|
| The Unfound Path | All 80+ dungeons | The Broken Crown | All 8 Shells |
| The Ashen Dawn | 60+ dungeons | The Ember Sigil | 5 Shells |
| The Drowned Truth | 40+ dungeons | The Abyssal Tome | 3 Shells |
| The Hollow Peace | Main story only | None | 1 Shell |
The Mortal Shell II ending achievement for the true ending, "The Unfound Path," is the most demanding because it requires near-complete exploration. You need to find all 80+ dungeons, collect every codex entry, unlock all eight Shells, and locate the Broken Crown hidden in the deepest chamber of the Drowned Labyrinth.
Ending Achievement Order and Efficiency
To minimize backtracking, community guides recommend a specific order for pursuing the Mortal Shell II exploration achievements and ending unlocks: Prioritizing the right locations first keeps your route efficient, because many collectible achievements share the same dungeon runs and can be earned together in a single pass.
-
First playthrough: Focus on the Hollow Peace ending while exploring as much as possible.
-
Second playthrough: Use Solomon to detect hidden passages and target the Drowned Truth ending.
-
Third playthrough: Equip Gorf to break reinforced walls and aim for the Ashen Dawn ending.
-
Fourth playthrough: With all abilities unlocked, complete every dungeon for the Unfound Path ending.
This approach ensures that each playthrough builds on the previous one, and you will naturally unlock most of the Mortal Shell II achievement count by the time you finish the fourth run.

Frequently Asked Questions
How many Mortal Shell II exploration achievements are there in total?
The Mortal Shell II achievement count includes 12 exploration-specific achievements, which is the largest category in the game. These range from discovering all dungeons to finding every mural and codex entry. Combined with lore, Shell, weapon, and ending achievements, the full list totals around 37 trophies across all categories.
What is the hardest Mortal Shell II exploration achievement to unlock?
The "Cartographer" achievement, which requires discovering all 80+ dungeons, is widely considered the hardest exploration trophy. It demands that you find every hidden passage, solve all environmental puzzles, and switch between multiple Shells to access ability-gated areas. Most players report needing at least three playthroughs to complete this achievement.
Do I need to find every Shell for the Mortal Shell II ending achievement?
Yes, the true ending "The Unfound Path" requires all eight Shells to be unlocked and activated. Each Shell has unique dialogue with the final boss, and these conversations are required for the full ending sequence. The Mortal Shell II shell achievements are therefore a prerequisite for the most complete ending in the game.
Can I unlock Mortal Shell II lore achievements in a single playthrough?
It is possible but extremely difficult, because several codex entries only appear after completing specific Shell quests or finding hidden murals. The Mortal Shell II lore achievements are designed to encourage multiple playthroughs, and most players miss at least a few entries on their first run due to the interconnected nature of the lore system.
Are there any missable Mortal Shell II exploration achievements?
Yes, several are missable. The Shadow Daggers vanish after the Hollow Cathedral boss, and the Sunken Bell requires ringing it before exiting the Flooded Crypt. Explore thoroughly before major bosses, since backtracking after a boss kill will not recover these items. For a full breakdown, see our missable achievements guide.
