Hello i want to aks what i means tha qi if i want buy i item for example
"PURE Blood" can i buy it if i have only 310 qi ??
their must be 10000qi
sorry for my english

QI is like level.
You're level 310
and Pure needs level 10 000, so you can't buy it.

QI is amount of matches you've played.
There are some items that requires exact amount of qi.

Let's say pure...You need 10 000 qi to buy it.

or play 10k matches

or you can buy qi in the qi shop, but that will be counted as "cheated" qi. They will not be counted in your lose/win ratio.
