aw... 2-5 points is so cheap, i only takes this features for cleaning the excess of the fragment then (will rarely open than page)

btw, would be more interesting if no need 5 stars to refine (make it 3 stars minimum) & min point is 10 (at shop, hinata @500coins & zabuza @500coins but why worth 10 & 2 in refine? none will buy that 'not used' zabuza)

cmiiw,
