Shin Megami Tensei V: Vengeance Demon Compendium & Fusion Guide
Explore the complete database of all demons in SMT5 Vengeance, including every demon added in the Vengeance expansion. Filter by race, level, and price to find the perfect allies for your Nahobino. Check base stats, elemental weaknesses, innate skills, and skill affinities at a glance.
Why use our SMT 5 Demon Database?
Our tool covers both versions of the game: the original Shin Megami Tensei V and SMT V Vengeance. Toggle the expansion from Settings to switch data sets — Vengeance adds new races like Qadistu, Enigma, UMA, Devil, and Primal, plus 60+ new demons and rebalanced skill rosters.
Innate Skills and Periapts
Vengeance demons carry innate skills they start every battle with, and periapt skills can only be transferred between demons that share an alignment or a bond. Each demon page flags its innate skill and every fusion spell it can receive.
Press Turn and Magatsuhi
Striking a weakness or landing a critical grants extra Press Turn icons, while hitting a null, drain, or repel affinity wastes them. Magatsuhi skills charged by the gauge, like the Omagatoki series, can turn entire fights around — plan your builds around them.
Demon Affinities
Every demon has per-element affinities that affect skill transfer costs and stat bonuses when using essences. The higher the affinity, the cheaper it is to customize your demon — check the affinity grid on each demon page before investing.
