10 ingot = 1 shuriken,

100 ingot = 10 shuriken

10 shuriken +/- = 60 points

300 ingot = 180 points equals to 1 box.

47*300 = 14,100 ingots.

Depends if you use that 14,100 ingots in Lucky Board / Lucky * you might score Edo Deidara / Hidan DPB / Masked Man or anything else this Kakuzu will come in as a bonus for spending. Not Bad but need some luck, unless you going for all power up item from Lucky Board then should be ok and nice too.

I would wait for recharge 30k events that gives tsunade 5th hokage and ay etc. Usually there is some other spending event as well like for example a few weeks back there was an event cycle in which you would have gotten ay edo deidara and you would still have 19k ingots left. I would suggest waiting for something like that.

Thank you for the advice guys (:

ill just get the few from this event naturally to make it cheaper when i do cash!
