I would like to share a good technique of upgrade. It save your nerves when doing such things as upgrade using token.
Get the item +6. And then
Go to https://www.random.org/
set the range of the number to 0, 3
hit the button twice and sum the resoults
if input 0 - then it does not count to a sum
ex. 0 3
hit the 3rd card
ex. 1 3
hit the 1st card
it's somehow effective
GL!
