There are few things that I love more than monsters, but a monstrous, invisible cat is definitely one them. So, if you need an adorably brutal creature to add to your wintery DnD campaign, I've got to recommend the Yule Cat.

First off, the price is very affordable at $0.00, so there's really no reason not to purchase this monster and favorably review it. Second, it's a well-done document. The layout is easy to read and pleasing to the eye, and, although the interior art isn't exactly detailed, it does fit the monster perfectly. There are a few typos, but it's eminently readable.

Best of all is that you get a sense of who the Yule Cat is, both as a DnD monster and as a part of Icelandic folklore. Eggertsson does a good job of introducing people to the folklore behind the Cat, embedding it into a larger narrative and helping you figure out where to put it in your game. He also gives you six plot hooks to use and the full monster stats, which seem balanced and correct. The Yule Cat ends up being a beefed up, magical panther/purple worm and could definitely do some damage against a party -- unless they wanted to try to befriend it, of course.

I definitely think it's worth it to "purchase" this monster, and Eggertsson seems like a good creator to follow in the future. I'm excited to see what else he has and figure out a place to put this kitty in my game!
