I downloaded Levi Kornelsen’s Skinchangers beta, which is free, and holy crap is the list of inspirations right up my apple cart: Werewolf: The Apocalypse and Neverwhere (paid link) meet Buffy (paid link) by way of Fate and Apocalypse World . . . yes, please!
At first blush, it’s incredibly clever — and I love the minimalist, yet evocative, artwork. And oh, this core mechanic; it’s fantastic.
I’ll probably butcher it here, but you roll a number of Fate dice equal to your ability, using “-” results to cancel dangers (associated with each action) and “+” results to boost the outcome in specific ways. Blanks do nothing, and how you undertake the action (cautiously, boldly, covertly, etc.) changes what results you get to reroll.
Here’s the core concept from the intro:
“You have met a powerful animal spirit. When you did, you were transformed and charged with a duty to the natural world. Those who desecrate the world are your enemies; this includes both mundane and supernatural foes. It is the supernatural threats, however, that you are best equipped to face, as nobody else is. You will seek out desecrated sites, battle monsters, and track down cults that draw their power by despoiling life. In this task, you will be joined by other Skinchangers, and aided by natural spirits.”
From concept to mechanics, this is exciting. I need to spend some more time with it.
