1. Release all movement keys (movement keys must be released or this will not work)
2. Jump
3. Hit skill hotkey
4. Resume movement
When done properly, your character will jump in the air, turn itself toward the target, use the ability as you land, and you can instantly move (i.e. continue kiting nearly seamlessly).
Tips: Run facing opposite from your target to get bonus damage. Do not back pedal i.e. running backwards while facing your target. Back pedaling will give a decrease in damage bonus. Aion auto-turns for you when you use a regular attack or a skill i.e. You don't need to be facing your target when you use a skill or regular attack.
You can also jump shot regular shots. Replace "3. Hit skill hotkey" with "Hit attack hotkey." I do this when all my skills are still cooling down to keep up DPS.
