Reddit reviews WoD Slasher*OP (World of Darkness)

Best monsters you can have are the ones you make yourself. That is to say, don't be afraid to throw some stats down as you see fit and give dots were you think they should go. As for powers and such, go with the theme of the monster you want them to fight.

Wanna have a werewolf stalking and killing livestock and even members of a small, isolated farming community that the group is passing through? Don't reach for the W:tF source book, go old school 'The Wolfman' on it.

Big bad is a demon? Take a day or two and watch a few exorcism movies (personal favorites are 'The Rite', 'The Last Exorcism', and 'The Haunting in Connecticut' they can give you some great ideas) and then just right down what powers you want to use and how effective most basic exorcisms will be.

Zombie plague can be fun if done right. Use normal NPCs and give them immunity to bashing and extra soak on lethal.

What if instead of a supernatural monster your hunters faced a serial killer like any slasher movie. There is a H:tV source book for that, but I like to make things on my own.

Monsters are always the easy part. The hard part is the tone and atmosphere. Nail those and your group will be seriously happy, I know I would be.
