How to use Signature Stone ?

玩玩玩家

Hi all,

I have quite some Signature Stones inside my INVENTORY-ITEMS, some of them i can use it to upgrade my Champs but some of the stones when i click "There are no applicable Champions for this item at this time" .

For example:

I have 5 Science 4-star Champs, when i click on the 4-Stars Science Signature Stones, the message in red says "There are no applicable Champions for this item at this time" .

The champion has to have his signature ability already awakened in order to use a signature stone.
