Troia Velos

is the first Noble Phantasm of Paris. An arrow shot with his utmost efforts, borrowing power for the sun god Apollo.
It overcomes any and all obstacles to land a guaranteed hit on the enemy's weak spot.
However, a prerequisite to doing so is knowing the enemy's weak spot.
A killer move against heroes with famous weak spots.
This doesn't apply only to Achilles. If his weakness is revealed, Paris could even defeat Siegfried, whose body was hardened by dragon blood... maybe.Fate/Grand Order material IX - Paris's Servant Profile, translated by ComunCoutinho on Reddit
