Hi!

The information below is based on information posted on our Naruto Online (EN) discord channel, which can be found here. Courtesy to all contributors in the "event-information" channel.

Each Lucky Board dice roll should give an average of 6-7 points per dice, and each dice costs 20 coupons/ingots.

Since it costs 68 points per Hiruzen Sarutobi [Edo Tensei] fragment, it would mean that each fragment costs around 227 coupons/ingots.

The cost will highly depend on how many fragments you need.

For example: The cost of 80 fragments of Hiruzen Sarutobi [Edo Tensei] would be: 227 x 80 fragments = 18160 coupons/ingots.

Hope that helps!
