Archetypes of Yig
This fantasy roleplaying supplement presents character options devoted to Yig, the cold-blooded and vengeful Father of Serpents. It includes five archetypes: a fighter with serpentine powers, a mesmerist who can entrance victims and transform them into snakes, a sorcerer bloodline that grants reptilian abilities, a swashbuckler who fights with serpentine grace, and a warpriest who controls snakes and can sire reptilian children. A cleric domain for worshippers of Yig is also included.
