A) Mark one against him.
B) If he's parallel with Arcueid actually having her true powers, that's mark two.
C) So it's some weird thing that is magic but isn't magic, and being exploited for the purposes of a crossover. Not helping.
D) Well, ignoring every 'become incorporeal' power is convenient.
E) I was talking about Avalon's regeneration. The one that keeps Shirou alive as a fragment of its strength. The secondary ability to 'displaced from reality'. You know, the reason that Saber was the eternally youthful, undefeated King of Britain. I wasn't talking about passive Servant durability. 

F) Wrong Gilgamesh; that's the Final Fantasy one, not the King of Heroes.
