Dark Firaga

A powerful spell that utilizes the power of Darkness and can only be cast by Terra. It fires a single shot of dark flames, similar to Firaga, except it can pass through an enemy and hit another directly behind it. The attack also has a chance of Blinding all those struck. Although its a Terra exclusive spell in Kingdom Hearts: Birth by Sleep, it is notable that Riku is also able to cast it as a Sleight in Kingdom Hearts: Chain of Memories.
