So in Hexenwald there is a ritual PCs can learn that allows them to become invisible for a quarter day but requires "the blood of witch, willingly spilt".
So...what's a witch in Forbidden Land terms? Can a PC become a Witch? If so, how? Is a witch just a female spell caster? Something else?
One of my pcs has learned this spell, and wants to know what qualifies as a witch. And honestly I am not sure.
