This article explains how to find and complete Proxima’s fourth Shell Memory in Mortal Shell 2: The Endeavor, a quest that unlocks the final upgrade for the Proxima shell. You need to locate the memory node in the Sunken Atrium, survive the associated trial, and return to the Shellsmith to claim the reward. Below is a detailed walkthrough, including the exact route, combat tips, and answers to common questions.
Background: What Are Shell Memories?
Shell Memories are special collectibles in Mortal Shell 2: The Endeavor that permanently enhance a shell’s abilities. Each shell (Proxima, Voss, Hadir, and Sol) has four memories scattered across the world. Finding all four for a shell unlocks its ultimate passive ability and a unique cosmetic. For Proxima, the fourth memory is the most difficult to obtain, requiring you to navigate a late-game area and defeat a mini-boss.
Prerequisites and Preparation
Before attempting Proxima’s fourth memory, ensure you meet the following requirements:
- Have completed the main story up to the point where the Sunken Atrium is accessible (after defeating the Abyssal Herald).
- Your Proxima shell should be at least level 3, with the “Resonance” skill unlocked (it helps with the trial).
- Carry at least two healing items (e.g., Royal Jelly) and a weapon with good crowd control (e.g., the Martyr’s Blade).
- Equip the “Verdant Ring” to increase stamina recovery, as the trial involves a lot of sprinting.
Step-by-Step Walkthrough to the Memory
- Fast Travel to the Sunken Atrium – Use the Sester’s Bell to teleport to the “Sunken Atrium” checkpoint. If you haven’t discovered it, head there from the “Flooded Crypt” bonfire by following the eastern corridor.
- Head to the Western Balcony – From the Atrium’s central fountain, go west up the stairs. You’ll see a broken railing on your left; jump across the gap to the balcony.
- Find the Hidden Passage – On the balcony, look for a cracked wall (it glows faintly). Use a heavy attack or a Hardened Strike to break it open. Inside is a narrow tunnel.
- Enter the Trial Chamber – The tunnel leads to a circular room with a glowing pedestal. Interact with it to start the trial. You’ll be locked in and must survive three waves of enemies: first two Grisha, then a pair of Venomous Stalkers, and finally a Corrupted Knight.
- Claim the Memory – After defeating the waves, a chest appears at the center. Open it to receive Proxima’s Fourth Shell Memory.
Combat Tips for the Trial
The trial is challenging, especially on higher New Game+ cycles. Here are some effective strategies:
- Use the environment – The pillars in the room can block enemy projectiles. Circle around them to separate enemies.
- Focus on one enemy at a time – Use the lock-on feature and keep your camera on the most dangerous foe (the Corrupted Knight).
- Parry timing – The Grisha have a telegraphed overhead slam; parry it to stagger them. The Stalkers are faster, so dodge rather than parry.
- Heal wisely – Only heal when you’re behind a pillar or after a stagger. Don’t heal in the open.
Common Mistakes and How to Avoid Them
Many players fail this trial due to a few common errors:
- Not breaking the cracked wall – The wall doesn’t look interactive unless you hit it. Use a heavy attack or a special ability.
- Starting the trial underleveled – If you’re struggling, level up your weapon and shell first. The trial scales with your level, but having more health and stamina helps.
- Forgetting to use items – You can use consumables during the trial. Pop a stamina tonic before the third wave.
- Dying after claiming the memory – The memory is added to your inventory immediately, so even if you die after opening the chest, you keep it. But you still need to return to the Shellsmith to unlock the upgrade.
Rewards and What to Do Next
Once you have the memory, return to the Shellsmith in Fallgrim. Interact with the shell station and select Proxima. You’ll see the fourth memory slot is now filled. Confirm the upgrade to unlock the passive ability “Echo of the Void”: when your health drops below 25%, you gain a 30% damage reduction for 10 seconds (cooldown: 60 seconds). You also unlock the “Void-Touched” cosmetic skin for Proxima.
Frequently Asked Questions
Is the fourth memory missable?
No, it’s not missable. You can return to the Sunken Atrium at any time after unlocking it. The cracked wall remains breakable, and the trial can be repeated if you die (the enemies respawn).
Can I get the memory on New Game+?
Yes, the memory is available in New Game+ and beyond. The enemies in the trial scale with your level, so be prepared for tougher fights.
What if I already used the memory on another shell?
Each shell has its own set of memories. Proxima’s fourth memory is unique to Proxima. You cannot use it on other shells, and there’s no duplicate.
Do I need to complete all four memories for the platinum trophy?
Yes, collecting all four memories for all four shells is required for the “Memory Hunter” trophy. This walkthrough covers Proxima’s last one.
What’s the best weapon for this trial?
The Martyr’s Blade is recommended for its wide swings and high stagger. If you prefer a faster weapon, the Hammer and Chisel works well, but you’ll need to dodge more.
