3.5k spent, which is 350spins (coupon value in brackets): 28seals( ~2800), 190oils (~1900), 90moods(~900), 5shisui, 5masked, 18adv threads(~900). Didnt count kakashi and coins. This event is still good. Would be way better if ninja frags there are something you need, but even without them this is a solid power up event on its own.
