|Darkness Dragon's Black Wrath|
Yamiryū no Kurodoki
Darkness Dragon's Black Wrath (闇竜の黒怒気Yamiryū no Kurodoki) is a Darkness Dragon Slayer Magic spell.
Mezar unleashes a black/purple, smoke-like miasma that radiates outward from him. The umbra immediately ages and rots anything that it comes into contact with. It can move fast enough to strike even the fastest of mages. Even after escaping the attack, the deterioration continues until the target's afflicted area had been amputated. Another notable aspect of the ability is that Mezar can control its speed. This spell can even dissolve certain spells, while some top-tier defensive or barrier spells and/or seals can only be partially damaged or can even remain untouched. Under normal circumstances, Mezar is protected from the effects of his own ability, as he himself consumes darkness to gain power.
