Unless the price changed, (Which I believe it did) probably around 10k-14k coupons.

It is better in the treasure of the sage you can get a 40% discount which equals

120*80= 9600 coupons

- Every Orb gives 9 to 13 points. 10 Coupons/Ingots = 1 Orb - Extra points can be obtained for free by doing daily missions max 10 points per day.

Jonin Minato unlock: 7,600 points (7,600-10,850 Coupons/Ingots)

Ive been trying to piece together minato for a while and i have to say this event is pretty good for its worth. I say go for it cause who knows when or if this event comes back

Thanks for all the comments. I think I'm going to go for it

No lol each orb doesn’t give 9-13 its 5-15 with 7.5 average around

i already got masked man so im going for minato jonin, but since theyre the same in terms of price, about 10-12k coupons for either one

Uhhh, no man, every orb gives either 5,10,15.

the average of an orb is 7, since almost always every 10 you do you get 70 or 75.
