Death Streak

Death Streak (死の祝福) is an offensive Nuclear Magic spell.

Abilities
When the Abyss Core generated by Nuclear Magic is crushed, the waves it releases agitate Spiritrons and cause them to release a radiation in the form of a Dark Light (闇の光). The Dark Light bypasses all physical and magical obstacles, rewriting the s of living beings and causing their death. Even the Souls of every being within its radius are destroyed by the Dark Light precisely piercing their Infons. The user can potentially take damage if handled incorrectly, with the Dark Light not discriminating between friend or foe.

The only way to counteract this ability is said to be to counter it with an equal "Dark Light", while the only ones said to have the potential of surviving it are Spiritual Lifeforms or those who can likewise store their memories within their soul and regenerate their bodies. However, for lesser beings, it is said that the probability of death reaches above 99.999% with one in a million having the potential to survive the technique. This is caused by their Soul adapting to the Dark Light, a process that turns the individual into a Monster if they're lucky enough to be compatible. Though there are no recorded instances of this ever happening, it is responsible for the spell being nicknamed as a "Blessing".

It is possible for the effects of the Dark Light to be toned down, only scrambling Genes and not targeting Souls.
