How to fuse Special Demons?

Special demons such as Alice, Beelzebub, or Metatron require specific ingredient combinations instead of normal level-based fusion. The generator automatically incorporates these special recipes and every demon's unlock conditions.

Elemental Fusion Basics

Fusing two demons of the same race always yields an Elemental: Flaemis, Aquans, Aeros, or Erthys. Fusing an Elemental back with a demon of its paired race shifts the result's level up or down within that race — the core technique for fine-tuning any fusion result.

Skill Inheritance and Affinities

Inherited skill slots are limited to four by default (eight with full customization), and each element inherits at a different cost depending on the demon's affinities. Use the affinity grid on each demon page to plan cheap, effective transfers.

Level Restrictions

You cannot fuse or summon a demon whose base level is higher than the Nahobino's current level. Story-locked and subquest demons unlock as you progress, and DLC demons can be toggled from the Settings menu.
