Yeryl's Super Happy Fun Murder Dungeon


Centuries ago, a beholder named Yeryl fled from the place of his birth and wandered the countryside in search for a place to call home. After many sleepless nights spent carving out a safe nook for himself in the wilderness, he at last slipped into slumber. In his dreams, he found an ideal place for his lair: long-abandoned ruins hidden amidst a dull and barren valley. Yeryl spent years transforming the place to suit his paranoid designs. Visitors were rare enough, and the few that made it to Yeryl’s lair were quickly destroyed or forced into the beholder’s service, building the lair ever deeper and more magnificent.

As time went on, Yeryl finally completed his task. Safe at last, but with nothing to occupy his mind, Yeryl was struck by melancholy; was this lonely and empty life truly what he had chosen for himself? On that day, Yeryl made a decision: next time an adventurer came to his lair, he would welcome them in. With this resolution in mind, Yeryl began to dismantle his traps and replace them with ones he considered to be more fun. Unfortunately, for all his good intents, Yeryl has not yet realised that killing people is a bad way of getting them to like him.

Yeryl's Super Happy Fun Murder Dungeon is a highly obnoxious and mildly ridiculous collection of traps, combat and puzzles designed to test your players' wits and patience. It is optimised for a group of four to five 3rd level players, but the text also contains a guide for level adjustments for different sized groups.

Minor question: In area 2 (p5) anyone who eats the cake has to make a DC8 Con Save. What happens if they fail?

I'm half of a podcast that reviews adventure modules called The Quest Hub and we've chosen this for our next episode! We're really excited to run it and talk about our experiences. We're also very dedicated to crediting creators and directing any interested listeners toward the products we cover. So I just wanted to ask if there are any sites or social media accounts you'd like us to send listeners who are looking for more of your content?

Hi Dane! I'm @luciellaes on Twitter, and you can find my other work (or links to it) on

I'll be honest and say I haven't been particularly active for a while, but I'm happy to answer any questions you have. Best wishes with the podcast!

The preview sold me (party horn, ftw). Bought 3 to get another one in the community pile (love that idea, here for it).

I'll report back after I've read it :-)

The maps included do not work for roll20. Are there any without numbers on them?

Hi there, sorry to bother you, but are there any maps that would be useful to use for PC's on Ie, maps without numbers on the areas?
Customer avatar
Adam M May 23, 2020 5:12 am UTC
No worries. I have modified the original maps for using with myself. If you'd like them Luciella, I am happy to send you them so that you can share them with purchasers as you see fit.

I'm glad you got it sorted, and sorry I missed replying! It wouldn't be right for me to take your contributions and embed them into the product itself, but you've prompted me to look at how I can make the module more digital game friendly, so I may add maps of my own sometime soon. Hope you have fun!

Hello! I'm extremely interested in running this module with my group on Roll20, and would really appreciate some pre-digitized maps. Would you be willing to pass along the maps? In exchange for perhaps a community copy of this module? Or an equivalent charitable donation?

My PCs loved this adventure, does anyone have any similar one-shots they would recommend?

Thanks! I'm glad you had a great time with it :) I'd recommend checking out the comedy filter for other silly adventures, or using the DMsGuild hashtag on Twitter. There's plenty of great content out there!

Here's another one that I wrote, which has a shorter run time but plenty of avian tomfoolery:

Or here's a different author's work, which is family friendly and benefits Extra Life:

Hope that helps!

My partner bought this to run, we didn’t get to befriend Yeryl and rather berated him at the end, I was getting ready to put my own party down when they suggested killing him. Sadly he floated off.

Brilliant adventure though.

Aww, poor little Yeryl! But I'm glad you enjoyed it :)

How difficult would this be to adjust for a group of 6 level 5 PCs?
Customer avatar
Luciella S July 16, 2019 11:19 pm UTC
Hi Justin,

Not super difficult, but you would have to make some changes based on higher attack power, and to recognise that players can use spells (Dispel Magic for example) to breeze through traps that might stygmie lower levels - not necessarily a bad thing as there are only so many spell slots.

The arcane trap on the first floor would be DC13 to dispel if spotted, and the effect on the following door would not require a check to dispel. The room with the shadow demon would be DC15. Fly and Leomund's Tiny Hut are also spells I pay attention to for scaling, but I don't think they make much difference in this case.

Combat is the big one. You can probably leave most of the smaller encounters as is or add an extra monster if you prefer, but I would suggest the following:
- Two ochre oozes instead of one and add an extra quasit to the summoning trap if those two encounters happen.
- For the two big monster fights, ramp up HP by at least 50% and add Legendary Actions...See more

Hello! Running this tomorrow night for two groups of 4 level 3 players.
Gonna have two DMs and they will fight the clockwork dragon at the same time and encounter reality-warping effects every so often where they trade places with an identical character at another table so parties stay balanced.
*Request: Do you have larger files of the maps provided in the pdf?
Customer avatar
Luciella S March 28, 2019 10:51 am UTC
Hey Thomas, thanks for asking! If you get this in time, I've added a zip file with some larger maps in image form, and have also added these to the PDF. Hopefully these meets your needs.

Best wishes for the game - the multi-table approach sounds like fun :)

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
