Abyssus Draconis

is an ability possessed by Georgios where he first establishes whether the target is good or evil, before temporarily transfiguring the target into a draconian being. In function, it appears to be associated with his red cross-emblazoned surcoat (St. George's Cross) or his paludamentum (the mantle and overcoat attached over his armor), but these are just a focus. The phenomenon is initiated through his unshakable faith, and the surcoat nor the paludamentum can be used to independently activate it as a Noble Phantasm.
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 at Beast's Lair.
