Why? Because with Urashiki you can farm 1000 diamonds guaranteed from World Boss every day. That is only from your own kill. You will get 20 diamonds from other people’s kills. If there are many people on your server who have Urashiki, the rewards are even higher. One guy from A388 said, he gets 6000 diamonds without participating in World Boss himself. Imagine all those diamonds going into your account DAILY.
And the best part of it? You only need 1 copy of Urashiki, no need for talent, no need for EX.
If you are f2p, saving diamonds is really important in this game. With enough diamonds, you can get OP ninjas from Limited Time Partner which runs every two weeks.
Based on the previous article How to get diamonds, you can estimate how many diamonds you are able to accumulate and save for a certain period, let’s say a month. Of course, you can use an excel spreadsheet or just estimate it on your mind.
What if there is a specific calculator for this? Fortunately, there is. Thanks to Elma Tetsuo from server A227, he created exactly this calculator.
