From publisher blurb:
Every campaign has a big bad guy, and every hero has an evil side.
Mage Hand Press presents Evil Archetypes, a book containing the most wicked flavors of every class, alongside a host of villainous characters to terrorize your heroes. Containing a dozen evil archetype options (one for each class), this book is the perfect choice if you want to run a campaign with a party of evil adventurers, as opposed to goody-two-shoes heroes.
Even better, this book contains a host of pre-made villains, ready to be dropped into any campaign. All 12 Big Bad Evil Guys come complete with NPC stat blocks, additional combat information, and a detailed backstory, so you know just how to introduce them into your campaign, and how to make them hurt your heroes.
