From publisher blurb:
The undisputed masters of handling monsters, tamers bring the fiercest creatures of the world into battle with them. With their encyclopedic knowledge of the dangers of the wilderness, a tamer will seldom find themselves alone in a fight.
Building off of the existing Fifth Edition rules for character creation, this PDF introduces a new class, the Tamer. These adventurers use their unique skills to bring companion monsters into battle.
This PDF contains three subclasses for the tamer:
The Trapper, who captures ferocious beasts to battle for them while assembling traps to redefine a fight.
The Dragon Master, who negotiates the assistance of chromatic dragons, and in doing so develop a legendary reputation themselves.
The Summoner, who captures the essence of fey, fiends, and elementals in an enchanted deck of cards.
