AC Coral Sky[]

AC Coral Sky

AC Coral Sky

Coral Sky is an exclusively close-range AC, equipped only with the best of blades, the MARS parrying blade and the infamous MOONLIGHT laser blade. Thanks to the DRAKE booster and powerful Overboost its core provides, Coral Sky is an extremely agile AC with impressive aerial time lengths, although its lack of armor makes it a risque AC to deal with against the much more powerful ACs.

In-Game Information[]

A rare breed, Kalchas attacks almost exclusively with blade weapons. Because of this, his victory rate isn't high, but his unit does boast one of the most impressive flight durations of any AC in the Arena. He's a loner and keeps to himself.


Kalchas is lethal at close range and can stay airbourne for long periods of time. That being said, stay out of range and you should have little difficulty defeating him. For those ravens looking to learn how to more effectively use their close range weapons, Kalchas makes for a good teacher to train with.



The name Kalchas (alternatively spelled Calchas), refers to a Greek seer who prophesied many events during the Trojan War, one of his prophesies stated that Troy would be sacked in the ninth year of the war.

The name Coral Sky is the original name for what is now know as the Cruzan Amphitheatre in West Palm Beach, Florida, United States.
