The Devil Trigger ability enables Dante and Lucia to transform into a demon form. This changes their appearance, increases their strength and defense, slowly restores health, and enables them to use special attacks and other passive and movement abilities, including increased speed and the power to fly. The Devil Trigger state lasts as long as there is power in the Devil Trigger Gauge, which increases by attacking or taunting enemies in the normal state and decreases by attacking in the Devil Trigger state or using Devil Trigger-only attacks. Unique to this game is the Desperation Devil Trigger — an enhanced form of the Devil Trigger — available to Dante when he is low on health.
