Eh long story short... Save coupons to buy sage naru from events. Pull Roshi (200~ seals) from jin 1 asap, then work on kage every 60 gona get u something nice and if u make 1k you get 4th ay or sasuke. Dont bother with tendo treasure, sage treasure (unless u wana go for hashi but still kinda a waste), edo treasure or seal treasure.
