Introduction

Welcome to the Lost Soul Aside Trophy Guide! What started as solo developer project back in 2014 finally sees the light of day in 2025. Platinum requires finding all collectibles, beating Nightmare difficulty, and beating bosses on Nightmare without using items. A minimum of 3 playthroughs will be needed because Hard difficulty is only unlocked after the first playthrough, and Nightmare is unlocked after the Hard playthrough. The same Trinket collectibles also have new versions on Hard/Nightmare difficulties so you’ll want to collect those again.

Step 1: Complete the game while getting all Collectibles

For your first playthrough, you’ll want to get used to the mechanics of the game while finding all the collectibles you can get during your Normal difficulty playthrough.

During this playthrough you should collect all of the following:

All 89 Documents to unlock Gethya’s Approval.
- Some of these documents will unlock automatically while progressing through the story, but some of them you’ll need to pick up yourself.
Locate all 9 Dispersed Dimensions
- You don’t need to complete all their bonus objectives when you find them. You can always complete them later on when you have better equipment.
Collect and craft all 11 Crafting Recipes
- You’ll automatically start with 1. You’ll need to buy the other 10 from Claudian at the start of every main chapter.
Purchase all 6 Arena Powers available on Normal
- On Normal Difficulty, you’ll only be able to purchase a total of 6 of the Arena Powers from Claudian. The rest will come from other means, such as the main story or rewards from Dispersed Dimensions/Boss Rush modes.
Collect the 41 Trinkets in Normal difficulty
- This is excluding Trinkets rewarded for completing bonuses in the Dispersed Dimensions, as that can be done later on. Some will be awarded automatically during the story, but most will need to either be found or bought. These Trinkets are unique to Normal mode, so make sure you collect them as collecting them on higher difficulties will result in a different Trinket.

Follow Lost Soul Aside Collectible Guide to get everything.

Step 2: Dispersed Dimensions Cleanup + Normal Boss Rush

After finishing the game on Normal difficulty, you can load your clear save data and it will put you back at the Imperial City and you have access to the new Boss Rush mode.

Now that you have better equipment, you can clear the Dispersed Dimension challenges to get the Trinkets and Arena Powers that are locked behind them. This will also unlock Dispersed Dimension Master. Make sure you complete all 3 challenges for each Dispersed Dimension, not just the challenge that rewards you with the Trinket/Arena Power.

Afterward, you can clear all 8 Boss Rush challenges, making sure to complete them all within the time limit to complete the challenges for Ultimate Gifted One. This will also reward you with more Arena Powers, of which you should only be missing 2 at this point: 1 Mountain Break and 1 Cage of Despair, which will be gotten later.

Step 3: Complete the game on Hard difficulty

With everything on Normal completed and collected, you can talk to Liana and go to the Stage Selector menu. Press to change the difficulty to Hard and start from the Prologue. You’ll need to complete the game from start to finish to unlock Best-Selling Author Liana!, and also to unlock Nightmare difficulty. All your skills, equipment, and trophy progress will carry over, so it’s also a great time to collect anything you might have missed.

During this playthrough you should collect everything below:

Any documents you missed to unlock Gethya’s Approval.
- Progress towards the documents carries over, so you don’t need to recollect any you’ve already collected.
Any of the Dispersed Dimensions you missed.
Purchase all unique items from the shops.
- This includes all of the Lifeforce Shards as well. Once you’ve bought all the Trinkets, Arena Powers, Crafting Recipes, and Lifeforce Shards you should unlock Shopaholic. You’ll also be able to buy the last 2 Arena Powers from Claudian, which are unique to Hard Mode.
Recollect all the trinkets again.
- On Hard Mode, the trinkets have a better version of them when found again, so make sure to recollect them all. If you missed any trinkets on Normal, you won’t be able to collect them here as you’ll only get the better versions.
Use your Sharp Alloys
- Defeating bosses that would have given you a new weapon on Normal will now give you Sharp Alloys on Hard. You can use these to upgrade your weapons to Tier 2 at Liana’s Workshop.

Step 4: Complete Hard Boss Rush

After completing the game on Hard difficulty you’ll unlock the ability to do the Boss Rush mode on Hard. It’s the exact same as the Normal Boss Rush mode, but the bosses are the Hard Mode versions. Make sure you complete all 8 of them within the time limit to unlock Surpassing Seleria. This will also reward you with more Trinkets.

Step 5: Complete the game on Nightmare difficulty

With everything on Hard completed, you can talk to Liana and go to the Stage Selector menu. You can press to change the difficulty to Nightmare and start from the Prologue. Just like before, you need to complete the entire game on Nightmare from the start to unlock Ultimate Legend.

During this playthrough, you should collect and do everything below:

Unlike Normal and Hard, there are no trinkets to collect on Nightmare. If you missed any on either difficulty, you won’t be able to collect them here as you’ll just get a tier 3 weapon accessory instead. There is only 1 trinket to be collected on Nightmare and it’s given to you automatically.
Any documents you missed to unlock Gethya’s Approval.
- Progress towards the documents carries over, so you don’t need to recollect any you’ve already collected.
Any of the Dispersed Dimensions you missed.
Use your Sharp Crystals
- Just like on Hard, there is a unique material for Nightmare to upgrade your weapons to Tier 3. You’ll automatically be given the Sharp Crystals this time around so you can upgrade your weapons once you get to Liana. Once you’ve done this for all weapons, you’ll unlock Arsenal.
Defeat Victor without using any items to unlock Sanctified Sword.
- Victor is encountered during Chapter 2 – Beside SkyMirror Lake. For more information on tactics, refer to Sanctified Sword.
Defeat Zana without using any items to unlock Hot Dance in Hot Spring.
- Zana is encountered during Chapter 3 – Neverwind Monastery. For more information on tactics, refer to Hot Dance in Hot Spring
Defeat Aramon without using any items to unlock Cleaving the Cycle.
- Aramon is encountered during Chapter 5 – Clash of Fates. For more information on tactics, refer to Cleaving the Cycle.

(Optional) Step 6: Trophy Cleanup

With all 3 difficulties completed, you can now freely use chapter select across all 3 difficulties to get anything you might have missed along the way.
