My Explanation: I'm putting my first point in Flash Jump for escaping oncoming monsters, such as in CPQ. Then I max Critical Throw whilst getting some Booster along the way. Then comes Haste for added mobility. I max Vampire next to save pots and ultimately gain a useful mob attack. After that comes Flash Jump for my final mobility buff, followed by the maxation of Booster for a longer duration time. I leave Claw Mastery at 7 because when Vampire is maxed, I won't be using stars that often, and the 1 Sudden Attack is for when I get Poison Sling next job (Because I saw a video of a level 88 Nightwalker using Poison Sling against the Newt Mini-Dungeon).
