becomes a master of using delayed spells as a battle tactic. He initially uses wind and light magic, though he begins to master lightning spells as well. He later trains under Kū Fei in martial arts to make up for his weakness in close combat, advancing very quickly (even learning how to do instant movement, otherwise known as shundou), and applies a strong magical barrier around himself to avoid damaging his frail body. His proficiency at learning is shown when he masters techniques Kū Fei says would usually take a month in only three hours. He also trains under Evangeline and Jack Rakan, which increases his combat and magical capability exponentially. He also learns and improves upon Evangeline's "Magia Erebea" to "load (supplementum)" & infuse the body with magic (Supplementum Pro Armationem). "Hell's Refining Fire (Sim Fabricatus Ab Incendio)": Absorbing the magic from the "Flames of Hell (Incendium Gehennae)" strengthens physical resilience and creates resistance to heat. The sinister nature of the magic also absorbs magic from living things upon physical contact. "Lightning Speed (Agilitas Fulminas)": Absorbing the magic from "Thunderous Gale (Jovis Tempestas Fulguriens)" grants the caster extreme mobility and "lightning attribute" to his physical attacks, as well as granting some immunity to weather magic.

Also with "Twin Vigor", both Negi's physical maneuverability and mental-processes increase dramatically, overcoming the fundamental weaknesses of the regular "Great Vigor". He also came up with a new spell: "Spell Synthesis: Lightning God Lance: Titan Slayer" which is a new high class lightning spell that he used to lure Jack Rakan into a trap in their gladiator match. Negi is also able to use a magic circle to stop and absorb an opponent's power in order to use their own strength against them (Agite Extractio, Negica Magia Erebea: Circuli Absorptionis Ex Tempore). Negi used this ability to fight Rakan to a draw. According to Evangeline's spirit clone, this is the ultimate ability of Magia Erebia, one
