The Physician

The medic warlocks are the best of the best when it comes to treating cures, illneses and ailgments. However, they are as likely to heal you, as are likely to hurt you if need be. You don't want to get on their bad side. The medics can get their powers from a god that spends their time studying herbs for their medicinal or afflictive value, from a powerful lich who used to be a druid obsessed with nature and flora, or a powerful plant creature who wishes to better their community or a community they grew to love.
