Black Flame

Dark Flame or Black Flame is a skill that allows the user to release flames from their body whenever they focused their internal magic force. By creating a field of magic, transforming it into flames, and then launching it away, fire can be created from thin air. The temperature of the flames can be adjusted based on how much magic is used.

Acquisition
Rimuru acquired this skill when he combined the Mimic aspect of the Predator skill, Flame Transform, Control Flame, and Deviant.

Following the combination, Rimuru loses Flame Transform, Control Flame and Control Water. In its place, he received Dark Flame and Control Particles. Resist Temperature also evolved into Cancel Temperature, eliminating the need for Cancel Flame Attack.
