FINAL FANTASY XV WINDOWS EDITION · Weapon: one-handed sword
Airstep Sword
A one-handed sword whose listed modifier halves MP consumption for Noctis's aerial maneuvers.
How it works
The weapon table lists Airstep Sword at attack 83, with +7 Max MP and a modifier that halves MP consumption in mid-air. The accompanying description says it reduces the MP of Noctis's aerial maneuvers. The broader sword notes describe one-handed swords as usable for airstepping; the source does not provide further conditions or a specific acquisition method in the supplied passage.
