Too late for laments.
Black Materia is a ground magical HP attack for Sephiroth, learned at level 33. It require 40 CP to equip (20 when mastered), 300 AP to master, has Ranged High priority, and can induce Wall Rush when fully charged. By holding the , Sephiroth will charge energy and summon a meteor to hit opponents. Uncharged, the meteor is flung from above Sephiroth very quickly, but has short range. Fully charged, the meteor descends from above the opponent slowly, pushing them downwards and exploding upon contact with the ground.
Black Materia returns as one of Sephiroth's HP attacks, now requiring 30 CP to equip (15 when mastered), 150 AP to master, and is learned at level 28. It is otherwise identical to its previous incarnation.
Sephiroth uses an attack called Black Materia which shares the animation with Cloud's Meteorain and Zack's Meteo Shots. There is no physical Black Materia seen in the attack, it is only in the attack's name.
Kingdom Hearts seriesEdit
When using his Meteor attack, Sephiroth rises into the air and extends a hand. A red orb of energy with a black aura appears and summons a barrage of meteors to attack Sora. Due to the orb's color, dark aura and power to summon meteors, this may be intended as a reference to the Black Materia.
Materia means "matter" or "substance" in Latin. It also means "subject" or "matter" in Italian, Spanish, and Portuguese.
