Gáe Bolg

Gáe Bolg is Lancer's only Noble Phantasm. However, it has two "modes" in which it can be used and these "modes" differ so much that they are treated as separate Noble Phantasms.

While it derives its name from, the barbed spear of , it seems to be based on the legendary spear of Odin,.

The Spear of Impaling Barbed Death
An ability that inverts the concept of causality, creating a phenomenon where the spear is thrust only after it has made contact with a target. When the true name of Gáe Bolg is invoked, the opponent has already been pierced before the attack is initiated, regardless of the path the strike must follow to reach its target. Agility is meaningless in avoiding this ability; the only defense is a high degree of luck, which alters fate ahead of time. In spite of this destiny-interference property and its accuracy, use of Gáe Bolg is economical, consuming so little Mana it can be used seven times without pause for recharge.

The Spear of Striking Death Flight
This technique utilizes the full potential of Gáe Bolg's curse, converting Mana into energy and releasing the accumulated power on contact after the spear is hurled. In contrast to the Impaling Barbed Death property, the Striking Death Flight is far less accurate, but it puts greater emphasis on raw power and has a wider area of impact, similar in concept to detonating an explosive device.
