Arcane Nihility (Japanese: 魔器・虚無の角 Magic vessel · horn of nothingness) is a weapon skill in the beast category which debuted in Fire Emblem Heroes. When its user's HP is not low, Arcane Nihility boosts its user's stats and reduces the foe's based on the foe's bonuses, boosts the user's damage based on their speed, and neutralizes effects guaranteeing the foe or denying the user a follow-up attack if the user's speed is higher than the foe's.

Accelerates Special trigger (cooldown count-1).
At start of combat, if unit's HP ≥ 25%, grants
Atk/Spd/Def/Res+5 and Atk/Spd/Def/Res+X
to unit, inflicts Atk/Spd/Def/Res-X on foe
(X = current bonus on each of foe's stats;
calculates each stat bonus and penalty
independently), and deals damage = 15% of
unit's Spd during combat (including when
dealing damage with a Special triggered
before combat), and also, if unit's Spd > foe's
Spd, neutralizes effects that guarantee foe's
follow-up attacks and effects that prevent
unit's follow-up attacks during combat. At
start of turn, if unit is adjacent to only beast
or dragon allies or is not adjacent to any ally,
unit transforms (otherwise, unit reverts). If unit
transforms, grants Atk+2 to unit, inflicts
Atk/Def-X on foe during combat (X = number
of spaces from start position to end position
of whoever initiated combat + 3; max 6), and
also, if X ≥ 5, reduces damage from foe's first
attack by 30% during combat.
