well premium summons can POTENTIALLY help u the best out of all of those. ANd i definetly wouldn't use SCs for farming , unless i was in a real gold crisys (dc tend to gather in time as long as u are patient anyway)


Hell , the 50 stamp card doesn't even give that much good stuff. Some more sp cristals and better aff items , but that's it. U might as well just keep on to them if you don't really have anything u want to use them for. Those extra items on the stamp card aren't worth 15 scs. But if you want to use them...dunno what to advise you. Personally , i'd try my luck on summons , but that's just me.
