Blitz is a Fighter Tech ability used by the Fighter job class, which halves the damage done by it but in turn doubles its accuracy. It can be learned from the Sun Blade for 200 AP. The power, range, and element of Blitz is based on the weapon equipped.
Blitz returns as a Fighter ability and functions exactly the same. It can still be learned from the Sun Blade, but this time for 250 AP. It can also be learned from the Gladiator class from the Sun Blade as well.
Blitz is a German word for "lightning". In English it is associated with quickness.
