Black Flame

Dark Flame (黒炎) is an Extra Skill Skill that allows the user to release very destructive black flames from their body. The technique uses one's internal magic, and the maximum size of a flame may reflect on their user's power.

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.

Dark Flame is also one of the base Skills for Hell Flare.

Acquisition
Rimuru acquired this Skill when he fused the Extra Skills Water Manipulation, Fire Manipulation, and Combustion via Unique Skill Deviant, resulting in the acquisition of Dark Flame and Molecular Manipulation.
