Dromeus Cometes: Comet Form (彗星走法, lit. Runner Comet?) is an ability of Achilles that is normally triggered by stepping out of his chariot, the embodiment of the legend that he is the fastest among all the heroes of all eras. Although his physical prowess is high, it is not an impossible standard for a Servant, but his speed greatly stands out, equated to instantaneous movement. It allows him to run through a giant battlefield in a single breath, and obstacles on the field will not slow him even as he charges through a dense forest. Its usage requires that his weak-point, the Achilles Heel, be exposed, but not many Heroic Spirits can keep up with his speed.
