I just picked up Orobor Worldforge's
Orobor Monster Manual • Kruweer (affiliate link) a few hours ago, and I'm quite happy with it!
The product is a single new monster for PF1, the titular kruweer, which is a fey that seemingly lives for terrifying opponents before it kills them. I was pleasantly surprised to see that this monster puts some of the new fear rules from Paizo's
Horror Adventures book to use; too often the supplementary stuff that they made for PF1 is overlooked by third-parties working on something that's thematically similar. Likewise, the monster's stat block is well-constructed; this is a creature which, if it's used intelligently, can be a serious threat to CR-appropriate groups. On the other hand, parties who are smart and have ways of dealing with fear-effects and can avoid being isolated in the fog should be relatively fine.
I also have to mention the artwork for the monster, which was exceptional. I'm of the opinion that artwork in RPGs is never as salient as when it comes to depicting new monsters, and that's definitely the case here. Looking like a gangly, emaciated deer with a perpetual toothy grin, the kruweer's appearance justifies its focus on fear.
If there was a place where this product fell down, it was with the two-page short story that was included after the monster entry. It wasn't bad by any means, but it didn't quite click for me. The format of centering the tale on the adventurers who become the monster's victims was a smart one, but I felt like their depiction wasn't quite as thorough as it needed to be. These kinds of stories hit hardest when we have a strong sense of who the characters are, since then we empathize with them more and so more keenly feel their fear and helplessness when things hit the fan. But whether because of the space limitations or because of stylistic choices, these characters weren't as fleshed out as they needed to be, at least for me, and so their ultimate fate felt somewhat muted.
I also have to say that this product's entry on DriveThruRPG is a lesson on the importance of using that store's tags. I search for new PF1 products by going to the Rules System dropdown, and then choosing the following nested entries: Pathfinder/Starfinder -> Pathfinder OGL/ORC -> Pathfinder OGL 1E. But for some reason, despite having made several PF1 products, publisher Orobor Worldforge has almost all of them tagged as being Pathfinder OGL/ORC and not using any further nested tags. The result is that choosing the "Pathfinder OGL 1E" tag filters out the rest of his products. It's only with this one that the Pathfinder OGL 1E tag was applied, and so appeared on my searches; it was upon seeing a release from a company that I hadn't heard of before that I looked up the rest of their stuff, realizing they'd published more PF1 products that I hadn't seen before due to the tagging issue.
I'll likewise note that while this sort of thing is rare, it's happened before. Publishers, please be sure to tag your products properly; if you don't, potential customers like me have a harder time finding your stuff in the first place.
And that's a shame, because if products like this one are what we're not seeing, then we're really missing out.
