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.
