Homebrew Witcher Species Details

Witchers are mutant monster slayers crafted to kill monsters and other evils. Children either given to or taken by the witcher order are brought to one of the hidden witcher fortresses that exist throughout the world and trained to kill. At one point respected now few are left in the world and they are scorned as mutants and said to bring disaster and disease. They tend to live twice as long as their parent race and are much more durable. 

(The way that this race works is that a player chooses any other medium sized race and replaces their racial and subracial bonuses with the ones of the witcher race. Any proficiencies granted by race choice are kept and becoming a witcher does not get rid of sunlight sensitivity.)
