What exactly does the Devil's Call status effect have? Is it supposed to call the Devil to appear in our dreams like it randomly can do because I used it and it is showing as an active Status Effect but the Devil didn't show up in my dreams that same night I used it?
Does the Devil just show up randomly whenever it wants when sleeping overnight or does it possibly show up during battles/fights with enemies or what exactly?
Whenever you get your next bad dream. You can use the restless powder to guarantee a dream, most dreams are bad.
does anyone else's insatiable hunger card just not give life steal or am i missing something for it to activate?
It does give lifesteal, you just didn't do the math. Think about how much damage you need to deal in order to get
any hp back. 1 / 0.05 = 20. So you need a card that deals at least that much. But the card also gives you "weak", reducing your damage by half. So double that for two turns.
I played this awhile back regularly and had built up a strong deck back then but Victorius has since nerfed a number of those cards I use to use.
I use to never utilize any card that had a negative/positive impact on both the PC and enemies but many of the cards do exactly that now.
If you had to choose between the following three cards, which would you choose and why?
They're all useless. I can't imagine a situation when any of those would help, even assuming I could draw them whenever I want. You can do more with less energy spent. In fact, all purple cards are useless.
All this being said, if the dev actually wants to make any progress, I would suggest not to worry about combat balance but actual story and content. Balancing all of the cards would take a very long time.
