I'm also feeling a bit lazy about playing them all, to be honest. Especially considering that the reward is just a single рубашка (generous Blizzard Kappa). But the mode is actually fun, and I enjoy it, if only it weren't so dependent on which final boss you get and which cards work well for him. I haven't encountered the Kobold King yet, but the most unpleasant one so far has been Darkness.
To sell my soul
