Giga Slave

The Giga Slave is the strongest spell that can be cast in the Slayers franchise. A spell unique to and created by Lina Inverse, Giga Slave directly calls upon the power of the Lord of Nightmares to unleash its power on its unlucky foe. The spell is a very destructive one, easily capable of destroying a piece of the body of Ruby Eye Shabranigdo in its incomplete state. However, the spell can destroy the universe if it is miscast or can't be controlled. And even if the spell is controlled, Giga Slave completely exhausts the magic reserves of its user and leave them temporarily drained of power. In the occasions Lina has been successful in casting the spell, her hair turns white temporarily as a side effect of using it. Because of the risks involved with using the Giga Slave, Lina only resorts to using the spell as a last resort.

Lina originally developed the Giga Slave at a young age where she combined chants from a manuscript of the Clare Bible talking about the Lord of Nightmares with the incantation for her Dragon Slave, unaware of their significance at the time. Her first use of the spell led an entire body of water to turn into a "sea of death" that no living life would ever grow or inhabit in. When she learned more about the nature of the spell from a complete copy of the Clare Bible in Slayers Next, Lina was able to perfect the spell and realize its true potential.

Incantation of Incomplete Spell

Darkness beyond blackest pitch.

Deeper than the deepest night.

King of Darkness, who shines like gold upon the Sea of Chaos.

I call upon thee, and swear myself to thee.

Let the fools who stand before me be destroyed by the power you and I possess!
