Im a f2p and I dont get seal scrolls very often is there a good way for a f2p to get some? I have 7 a the moment and Im level 67 and I dont know what to spend them on because I know if id spend them on Tendo ill just get kakashi or guy, Ive gotten zabuza 7th swordsman and kakashi from Tendo box. But should i save them up for level 70 sage box? Or should i pull from seal treasure? Also what are the drop rates of th listed ninjas between the three?
