I noticed that a bunch of higher level J players are using aerial basic attack chains, but I can't seem to get him to do more than his standard flying kick. Is that related to the weapon I'm using? I know there are differences between each one, but I haven't been able to find any documentation on that for him since he's new.
Do you have the Third Skill Note for his skills? Keep in mind the Skill Note System works as follows:
1st note (Usually at level 3 of the skill) - upgrades the skill
2nd note (Usually at level 6 of the skill) - allows you to use the unupgraded version of the skill in midair
3rd note (Usually at level 9 of the skill, drop only) - allows you to use the upgraded version of the skill in midair, this is recommended for arial combos.
Also weapon Core determines most of your attack speed, with other bonuses such as tuning or Yuri Buff.
