You are a witcher- a hybrid humanoid that has undergone arduous trials, that changed your very physiology itself and cursed your blood. Above all else, you are a monster hunter that seeks to maintain balance in this world for but a price of coin. It is not an easy life, and not one most choose, but it is an honorable mantle to take. You risk life and limb each day to protect the people from creatures that would seek to harm them, or otherwise would want dead. Are you a righteous witcher who uses their powers for good, or would you rather use your abilities for more nefarious deads?
Witchers are resilient in combat and have the constitution equivalent to 10 men. They are almost impossible to fell besides means of traditional combat and magic.
The witcher is granted immunity to disease and resistance to poison.
