RAIDOU Remastered: The Mystery of the Soulless Army Guide | How To Fuse All Demons

Welcome to the ultimate guide on how to fuse every demon in RAIDOU Remastered: The Mystery of the Soulless Army. If you're aiming to unlock the Unbound Summoner trophy and achievement, you must capture and fuse all demons available in the game.

With a total of 127 demons to track down, this guide will walk you through the process clearly and effectively. You'll learn the core fusion method, what to prioritize, and how to tackle the more complex fusions like Legion and Case File exclusives.

Everything here carries over into NG+, so don't worry if you miss something the first time around.

Laddering Fusion Method

One of the primary techniques to achieve complete fusion is laddering. In this method, you use an Elemental to upgrade one demon to the next within the same order.

For example, Gold can be upgraded to Arachne using this method because both belong to the same order. This technique is vital for progressing through a specific demon lineage and filling out your compendium efficiently.

Demon Orders and Totals

You need to kill 127 demons in order to unlock the trophy. Except for the Pagan order, which has 18, most orders have 16 devils. Review your list often to make sure you don't lose track of any demons. It's important to check your collection again, especially before you finish the game or get to a point where you can't go back.

You are encouraged to pause during any moment in your journey and verify which demons may be missing.

Fusion Coverage

Except for Legion and the Case File specific demons, every demon can be obtained through the laddering method. This makes the process streamlined once you understand the elemental interactions and the structure of each demon order.

All demons carry over into New Game Plus, so don't worry if you're not able to collect them all on your first playthrough. You can continue the fusion process in a second run and complete your collection then.

Legion Fusion and Variants

There are five different variations of Legion that you must obtain for the Unbound Summoner trophy. These specific demons cannot be acquired through normal laddering or fusion paths.

Instead, they must be obtained through fusion accidents. These are random events that occur during fusion and result in unintended demons. Triggering these accidents requires a specific set of conditions and patience.

Refer to the pinned resources or guides available in community forums to understand the best ways to manipulate or increase your chances of getting fusion accidents. Securing all Legion variants is essential to complete your demon roster.
