Usage

Passive

  • [Passive, True] Authority over Spacetime - When the user of Acnologia is able to locate the six Between Time Grimoires(found in ancient cities or rare drop from wardens), by collecting six of them, the user is able to learn Spacetime Manipulation, when it is mastered, they obtain Spacetime Domination so long as the user has Law Manipulation.
  • [Passive, In-Slot] Supremacy Resistance - The user cannot be charmed or named. When mastered, the user is immune to Fear.
  • [Passive, Toggled] Dragon Body - The user's Attack Damage is increased by 10, their Spiritual HP by 3,000 and their HP by 1,000.

Active

  • [Active, Held] Magic Devouring - The user uses a predation-like ability to completely devour magic. This predation allows the user to devour only the Magics a person knows, and instead of dealing damage, directly drains the MP of a target by 1.5% per hit (3% when mastered.)
  • [Active, Held] Giga Flare - The user fires off a beam from their mouth, this beam does raw Magic Damage. It does 300 Magic Damage (400 when mastered) each hit.
  • [Active, Press] Eternal Flare - The user can produce several collapsing stars from the sky, these do both Gravity and Magic Damage. It does 100 of each (150 when mastered). The stars will automatically attempt to hit all nearby enemies, when shift used, all the stars will target the entity you look at.
  • [Active, Press] Light Plunge - The user fires a beam from their hand. This beam does 300 Magic Damage and instantly destroies Magic Circles and spells being casted.
  • [Active, Held] Hegemony - The user releases a powerful aura from their body to deal magic damage to all nearby entities. It does 100 Magic Damage, and applies a level of Fear like Haki does.
