What transformations do you use?
I played with currency for the first time yesterday and found that I copied just one ability (Gandayah got Healing from Faerie), all the rest currency went into copying abilities to my character (3 so far). I have impression that it is the most efficient way of spending currency in the long run since I can lose/replace demons soon. Or am I doing it wrong?
I love currency system, finally my decision paralysis is over
