To get this trophy, you will need to reincarnate at Sinca Pilgrimage, which opens up after you beat the game. You'll get 200 skill points for leveling all the way to 50 (enough to master two skill sets). Each time you reincarnate, you get to reset your skills and will earn an extra 40 skill points (up to 4 times, which means an extra 160 points after 4 reincarnations). Note that when you master a set of skills, you will get a star next to that skill set, and that star will carry over through the reincarnations.
