The Deathdealing (致死量ザ・デスディーリング, Za Desudīringu; Japanese for "Lethal Dose"): Askin's Schrift grants him precise control over lethal doses. After taking a particular substance into his body (usually by ingestion), Askin can then calculate its "perfect lethal dose" (完全致死量, kanzen chishiryō) — how much of that substance will 100% cause death — and adjust that value as he sees fit.[120][121] By lowering lethal doses, Askin can make normally harmless or even vital substances (like blood,[122] Reishi,[121] or select chemicals like oxygen and nitrogen[109]) become deadly "poison" to enemies around him, killing or incapacitating them without needing to attack head-on; for example, by drinking blood, Askin can make opponents be killed by the very blood coursing through their veins.[122] On the other hand, by drastically raising the lethal dose of a harmful substance or energy he absorbs (including an enemy's Reiatsu), Askin can develop an "immunity" to it, such that he becomes invulnerable to his enemies' powers following sufficient exposure to their attacks.[123][124][125]
Poisoning (中毒, Chūdoku):[121] By lowering the lethal dose of a substance that enemies are exposed to or hold within their bodies (like blood or Reishi), Askin can make it fatal to them, pushing said enemies towards death. This "poisoning" effect seems to be faster the more Askin ingests of the target substance,[126] and by decreasing the lethal dose of something vital like blood, he can make death all but certain — e.g., Askin may poison his opponent with their own blood so that, if they bleed themself to go back below the lethal dose, they instead die of blood loss.[122] However, particularly strong opponents take considerably longer to be disabled or killed and may require extra-thorough poisoning, due to their high endurance.[38][127] In order to facilitate the effects of his Schrift, Askin can release a tangible "poison" from his body that appears as a purple-violet (or green) miasma, and which he may either launch as projectiles[105] or expand over the battlefield to make whoever touches it near-instantly succumb to his Schrift's effects.[128]

Askin holds four Gift Balls.
Gift Ball (毒入りボールギフト・バル, Gifuto Baru; German and Japanese for "Poison Ball"): Askin conjures one or multiple[38] slow-moving balls of poison to throw at an opponent[105] or keep suspended in midair.[129] Anyone who touches these purple balls will near-instantly succumb to The Deathdealing, with a
