Dark Firaga
From Final Fantasy Wiki
Dark Firaga is a spell in Crisis Core -Final Fantasy VII-. The spell looks very similar to the Firaga spell, but may inflict the Poison and Silence status effects when cast. This Materia can only be made when a normal Firaga Materia is fused either with Poison or Silence materia, or when a mastered Dark Thundaga is fused with a mastered Blizzaga or Dark Blizzaga materia.
