SMT III Nocturne Optimal Fusion Recipe Generator

Create the Ultimate Demons

Our advanced fusion calculator uses Breadth-First Search (BFS) algorithms to instantly find the absolute shortest fusion paths. Transfer essential skills like Focus, Pierce, or Life Gain to any target demon without the headache of trial and error.

How to fuse Fiends and Special Demons?

Special demons, such as the Fiends (Matador, Daisoujou, Mother Harlot), require Deathstones and specific Kagutsuchi moon phases. Our calculator factors in these special conditions, elementals, and Mitamas to provide foolproof, step-by-step fusion recipes.

Mastering Sacrificial Fusion

During a Full Kagutsuchi phase (FULL), you can perform a Sacrificial Fusion by offering a third demon alongside the standard two. This unique mechanic transfers bonus experience to the newly fused demon, allowing it to level up instantly. Furthermore, a Sacrificial Fusion increases the number of inherited skill slots, making it the most powerful method to pass down crucial passive skills for your endgame party.

Enhancing Demons with Mitama Fusion

Mitama Fusion allows you to combine your demon with a Mitama (Ara, Nigi, Kusi, or Saki) to significantly boost its stats without altering its level or race. It is also an excellent tool for inheriting specific skills missing from your demon's build. However, this power has a limit: a demon's stats can only be increased by a maximum of 100% of its original base stats (e.g., a demon with a base Strength of 15 can only reach 30 through Mitama Fusion).

Mastering Elemental Fusions

Elementals (Erthys, Aeros, Aquans, and Flaemis) are created by fusing two demons of the same race. These Elementals are essential stepping stones for ranking up or down within a specific race, and are required to create Mitamas for stat boosting.

Cursed Fusions

If the Demi-fiend is Cursed (a status ailment), the fusion rules change entirely. Cursed fusions often result in Dark-aligned demons that are incredibly difficult to obtain through normal negotiations or standard fusion paths.

Level Restrictions

Always keep your Demi-fiend's level in mind. With very few exceptions, you cannot fuse or summon a demon whose base level is higher than the protagonist's current level. Plan your fusion routes according to your current progression.
