Dissidia Swordslash is a ground and aerial physical Bravery attack, learned at level 9 for the ground version and level 23 for the aerial version. Both versions require 30 CP to equip (15 when mastered), have Melee Low priority, and can induce Chase, while the ground version requires 120 AP to master and the aerial 80 AP to master. Firion does a quick, short-ranged sword slash.
Dissidia012 Swordslash returns as a Bravery attack for Firion, now learned at level 16 for the ground version and level 30 for the aerial version. Both versions now require 90 AP to master, but are otherwise identical to before.
