yes, now in korea noob stone (u6-u21) very expensive like maluriddle said. expensive item, but always sold out, then u55+, incl. u60 white stone. but not like at ur picture.
oh..card upgrade system has a gap. with noob stones trick, u can read the pattern. and, in upgrade system has a bonus pattern too. 4 times success in a row. this not about luck, but using logical and algorithm.
I will explqin later or raditzroom now i go sleep lol
Well nvm i do it now lol
First u need lot noob stones and noob armour
Then when u have to choose cards on nOob armour an u get succes at first time then get ur normal armour
But dont close upgrade menu cus then it will reset
Then choose the other card on pro armour . Ofc with white stone
So for example
Noob armour : i choose left and i get succes
S-f-b
Then on my normal armour i choose middle
But dont close the upgrade menu
But if you get middle or right card succes on noob armor, how will you know what card to choose on pro armor?
