Interfectum Dracones

is a gestalt Noble Phantasm possessed by Georgios that is brought forth through his nature as a Dragon Slayer and the capabilities of his sword Ascalon to deal massive damage to beings of draconian origin. It is another form of Ascalon. Although the Noble Phantasm will take on the form of a sword slash at close range, the sword can be used as a medium to shoot what takes on the form of a javelin of light to pierce the opponent at long distance.
This Noble Phantasm was not used in Fate/Grand Order but the ability was granted to Ascalon.Fate/Grand Order material I - Georgios, p.214-221, translated by You.
