Funtastic adventure with lots of humor, pretty well-balanced combat, good setting which can be dropped into an existing city. There are also plenty of vague clues that a DM can change or use to connect this with a next adventure. We really had a great time with it and my players were wise enough to talk to NPCs at the right time to avoid possible TPK. Really loved this one! Thank You!

Played it with some friends as a starting adventure at lvl 1. Allthough my first ever character died in this dungeon I had a blast and it got me hooked on Dungeons and Dragons.

Fully fleshed out story, great encounters, fantastic loot, great story potential. Would read again.

Great maps, fantastic story and great scaling options. I have a party of lvl 3 adventurers diving into this at the moment and they are really enjoying it! The option of tieing it in to the Fiery Grog Tavern is also brilliant!

Absolutely LOVED this! Ran it in combination with the Fiery Grog Tavern module that's an optional sister module. A friendly warning to DMs (and possible spoilers): Make sure you check with your players about phobias beforehand. I thought I was good but spiders had never come up before this and it STRESSED my players out. Also prepare for your players to try to take a rat bear pig as a mount, and Nibbles the rat as a familiar because mine were OBSESSED. 10/10 would run again for another group.

I've played this game a few times for a few different groups, and they have all loved it. The map is terrific and the NPCs are interesting. Each time I've run it the players take it in different directions, and this short but sweet game allows for plenty of different directions. This can easily fit into a larger campaign or just as a simple one-shot. I've fit it in a larger campaign myself, but mainly use it as a test game to see if I like the players before starting something more longterm.

Fit this easily into my ongoing campaign and even came out of it with some long-term NPCs that the party took to.

There's a great variety of enemies, which makes for tactical combat, as well as a fair mixture of puzzles, hidden items and... moral dilemmas! I enjoyed running this as much as the party enjoyed playing it, which speaks volumes.

More importantly for me, and possibly others, is that there is enough detail here to kick-start a campaign, but also not too much detail that you can't add some of your own campaign's lore into it.

Highly recommended.

Very good adventure. Great map, good descriptions & detail. Was very easily able to place this in my world. Used the Fiery Grog as the entry point. I loved that it was suited for low level characters, but had a feel of its own. 2 of the party were seasoned players (started in the mid-80's) and nothing was stale. Recongnizable, but different creatures/obstacles. Great flow. All around a great module. The only complaint I had was that I thought some of the magical items were a bit over powered for a low level adventure, but that was easy to overcome, I simply adjusted or swapped as I saw fit. Would whole-heartedly recommend.

I've DM'd this adventure over 3 sessions now and it's absolutely a blast! The rats seemed gimmicky when I read about them, but they work really well when played out. I'm not a huge fan of the (imho) overpowered artifacts, and some of the encounters seemed a bit too rough for my party of 3. But all of that was easily changed on the fly. I'm definitively going to run this again as soon as I get an opportunity!

A great twist on the "go kill some rats" adventure. It provides some fun new enemies and several hooks to further adventure. Be sure to start it off in the Fiery Grog Tavern.

I ran this in two sessions for a group of 4 PCs and everyone had a great time. The tone is unique, the monsters memorable, and the treasure evocative. The main issue I have with this adventure is the layout of the PDF making it difficult to use at the table.

Just sitting and reading the book before running, it read a bit campy to me with all the ridiculous rat hybrids. However the perspective is much different for the players at the table: it's hard to read a "spider rat" as silly when one has just dropped from the ceiling and is hugging your face. The panic and paranoia generated by these wild hybrids was much more effective than I expected, so I progressively leaned harder into the weird and dark elements as the adventure went on. This weirdness was all the more effective given the bone-standard fantasy plot hooks: missing boy went searching for a priceless artifact, rescue the boy and maybe find what he was looking for.

The treasure in the adventure is excellent. Even though I gave some of the items different stats and effects to fit into our game, the items each had enough personality that I could change the specifics and still keep the flavor. That's some good writing. A few of the items have built-in puns or jokes. Again these read as campy when read in a vacuum, but during the course of play they served as welcome comic relief punctuating the escalating horror of the adventure.

I very much appreciate the author's treatment of the eponymous Rat King and his familiar, Nibbles. For each, the author presents clear motivation and desires, giving the DM wide latittude to roleplay these as three-dimensional characters instead of dungeon obstacles to be steamrolled. Even the "insane," violent, kidnapping, mad scientist Rat King is somewhat of a sympathetic character if the PCs are able to get him to talk. Depending on how much of the cavern they've explored prior to that encounter and thus how much paranoia they are feeling, the PCs may even realize that keeping the Rat King alive may be key to preventing an even greater threat...

All of this plus high-quality maps in a PWYW package makes this a killer deal easily worth 5 stars. There were a few issues however. Most notably, the layout of the PDF was continually distracting to me DMing at the table. The text is very dense on these pages and the various rooms' descriptions are all visually similar in the "chambers and encounters" section, making it very hard to keep one's place while using the pdf at the table. My players experienced certain details in different places than they are keyed on the map simply because I accidentally read from the wrong text. I'm capable of changing things on the fly so it worked out, but I often found myself pausing to find the text I wanted to read. Given that this is an electronic PDF and extra pages thus cost nothing, I feel like the author missed an opportunity to add some space and art to break up the text and make it easier to use.

My other issue with the pdf is minor, more of a suggestion to the author. It's awesome that the maps are distributed as hi-res images along with the pdf, but that makes the relatively hi-res map in the pdf superfluous. Scrolling past the map in the pdf takes several seconds and on lower-powered devices such as tablets and chromebooks, again leading to undesirable delays when using this book at the table. My suggestion is to use the lowest acceptable resolution in the pdf when you're also distributing the maps separately.

Edit to add: I've since found PDF optimizer tools that can help with this last issue. I'd recommend them to others with the same issue.

I really liked this. It meshed well with the Fiery Grog Tavern and I was able to build this into a really nice introductory series of sessions. The rat names could give the impression that this is not a serious adventure, but if you DM it right, this can be pretty dark and definitely dangerous for a low-level party. It also has some decent NPCs to role-play with, and provides some good hooks for further adventures. Definitely worth picking up. Thanks!

Solid work. The maps alone are worth the price. I have to add extra words so I can post this.

I love this adventure! I've run it twice to great success and everyone loved it. I think it's clever and creative and funny. I recommend it to everyone who asks me for a recommendation of a one-shot, and so far, everyone has come back and said that they had a great time with it.

I ran this in conjunction with The Fiery Grog Tavern as the first adventure for a group of new players. They enjoyed exploring and really latched on to the mystery of the old cult. It provided a good challenge with the explodey rats in particular that created a good balance of not being too letal but still giving a sense of danger.
