I'm not familiar with the lore from the Witcher universe, but if this cinematic is to be believed then being a witcher is a punishment, or at the very least, a curse.
In The Witcher 3: Wild Hunt launch cinematic, Geralt of Rivia goes after some shapeshifting ginger monster.
I feel like the fight will be pretty indicative of what combat will be like in The Witcher 3: Wild Hunt will be like. It will very hard. Also drinking toxic potions and accepting some level of injury will just be the way of things. I can't wait.
The Witcher 3: Wild Hunt is out on Tuesday.
