Demon Fusion – SMT V guide

In this Shin Megami Tensei V Demon Fusion guide, we’ll explain the process, the rules, and the limitations of Demon Fusion.

SMT V allows you to recruit demons into your party. They’ll level up alongside you, and you can even teach them new Abilities. You can also take two (or more) of your demons and merge them into something new through a process called Demon Fusion.

To perform a Demon Fusion, you’ll need to head to a Leyline Fount and visit Sophia’s World of Shadows. Demon Fusion allows you to choose two demons from your party or demon stock (or Demon Compendium) and combine them into a new type of demon with new Abilities, Affinities, and appearance.

Demon Fusion is a great way to find (create) new allies without having to recruit them from the wild.

Types of Demon Fusion

There are four types of Demon Fusion listed when you talk to Sophia.

• Dyad Fusion is where you choose one of your demons and see the resulting fused demons that are available when you combine them with each of the other demons in your party and stock.
• Reverse Fusion shows you the resultant demons and then the demons you’ll need to sacrifice to create them.
• Reverse Compendium Fusion works like Reverse Fusion, but it isn’t limited to only the demons in your party and stock — you can pull demons from your compendium (demon’s you’ve encountered or recruited before) by paying Macca.
• Special Fusion creates a very powerful demon out of two to four demons.

Demon Fusion limitations

The first limitation on fusing demons is that you need to have them in your demon stock or recorded in your Demon Compendium.

More importantly, though, you cannot (intentionally) fuse demons that result in a demon of higher level than the protagonist. The only exception to this is Fusion Accidents that are more likely during a full moon.
