Upgrading hero with sanctify I and II etc.

Hi,

I updaraded Alexa to Saint I after I picked card 2nd time in tavern.

Then I mangaged to get that gard again some days later, and tried to pull off a Saint II hero. It posted successfull but nothing more happened.

How do this work ?

Well, go to "HEROES" tab and press sanctify, and you will see if it was successfull.
