Sage treasure is quite possibly the best thing in the game for free players, barring a few unlucky exceptions, it takes no more than 120 seal scrolls to gain the quasi equivalent of a super rare ninja. For months I recommended every single of my players to get that ninja and also recommended it to everyone that asked me questions on how to improve. Sage naruto will get you through ninja exams, pvp, arena pvp and instances of all sorts, 120 seal scrolls is an absolute bargain for that kind of utility! There are mny things wrong with this game, but the sage treasure is certainly not one of them.
