Wow... one of the few books I've actually read. I don't even remember how I got ahold of it. My father always had a long list of stuff he wanted me to read, and then there was school. Somehow I ended up with this book instead and it was awesome. TBH I don't remember most of it now. I remember parts about Czernobog. I know who the main God is that they're following. Unfortunately I remember the punchline of the whole thing as well... but it's a really good twist.
Nowadays when people start to get killed by fireballs, no one says they need to dodge the fireball anymore; they say they need to go get a fire resist ring and some ice damage so they don't have to.
