Really, I can’t even pronounce that. Let me just call it Chandler’s Book of Stuff That Will Give You Nightmares.

Lusus Naturae is a bestiary of monsters designed for Lamentations of the Flame Princess but it’s pretty easy to convert it to whatever OSR game you want. This isn’t your run of the mill collection of demons, forgotten horrors, or orcs and goblins who have an additional odious habit. These are wild, weird, eat your face, swallow your soul, ruin the rest of your day type monsters. Like I said, it’s designed for Lamentations of the Flame Princess so if you’re experienced with any of those adventures (like Death Love Doom (AL)) then this is right up your alley.
There’s lots of cool stuff in there. There’s actually a connection between many of the monsters. Some created others. Some like or hate others. It all just depends. Also there’s a neat little thing that some of them have. “Killing Blow” He who kills the monster gets something. Maybe something good. Maybe something bad. But this is for Lamentations so take that as you may. And you get away without having a cool crazy monster generator.
I think my two favorites (so far) have to be Doctor Volt and the Gelatinous Hypercube. Yes, Doctor Volt. A supervillian teleported to a fantasy world. Hehe. And the Gelatinous Hypercube. Well. I think the name pretty much says it all.
I can’t not mention the art. I usually don’t bother mentioning art but in this cast I will make an exception. Gennifer Bone did a great job making bring these these nightmarish creatures to life. The art is cool and disturbing as it should be for this book.
So this gets a big thumbs up from this guy. Now I’ve got about a half dozen ideas bouncing around inside my head.
