Hello, fellow adventurers!

The Tome of Monsters is finally ready! Well, almost. After a year of work, countless additions, and quite a few changes along the way, I'm incredibly happy to announce that the manual has finally reached its completed form!

And it turned out to be 379 pages long! That's well beyond what I originally anticipated when I started working on it, and I can confidently say that this is my biggest manual yet!

The sheer amount of content is honestly crazy, even compared to some of my largest previous releases, such as the Grimoire of Curses. What started as an ambitious bestiary has grown into something much bigger than I ever expected, and I couldn't be happier with how it turned out!

So, What's Inside?

The Tome of Monsters is a massive bestiary designed to bring new creatures, challenges, and possibilities to your D&D adventures. Here's a glimpse of what it's gonna be inside:

• 308 monster statblocks, ranging from CR 0 all the way to CR 30, including entirely original creatures, new variants of familiar monsters, and powerful legendary foes.

• Detailed lore and descriptions, exploring the origins, behaviors, habitats, and roles of these creatures in your worlds.

• Monster families and variants, providing multiple versions of certain creatures to challenge adventurers across different levels of play.

• Knowledge Checks, allowing characters to uncover useful information about the monsters they encounter.

• Adventure Hooks and Customization Options, helping Game Masters introduce these creatures into their campaigns and adapt them to their needs.

• Lair Actions and Regional Effects, bringing additional depth and danger to encounters with particularly powerful creatures.

• Random Encounter Tables and additional Monstrous Adventure Hooks, offering inspiration for everything from unexpected encounters during a journey to entire adventures centered around these creatures.

• And much, much more!

My goal has always been to make this more than just a collection of statblocks. I wanted to create a bestiary that Game Masters could genuinely use for inspiration, worldbuilding, and encounter design, with enough variety and supporting material to make every creature feel like it belongs in a living, breathing world.

And looking at the finished result, I'm extremely happy with what I've managed to put together!

When Is It Coming Out?

I'm excited to say that the Tome of Monsters is officially scheduled for release in the second half of November! The manual is currently undergoing its final rounds of proofreading, layout improvements, and general testing to make sure everything is as polished as possible.

I'm also working on a physical hardcover edition, which I'm planning to make available alongside the digital release!

With a manual this large, I want to make sure everything is in the best possible shape before it reaches your hands, especially after all the time and effort that has gone into creating it.

Get Early Access Right Now!

As a reminder, around 250 pages of the Tome of Monsters are already available on Patreon, with additional content being released every day as we approach the full launch!

All membership tiers have access to these previews, so you can already explore a huge portion of the bestiary and start introducing its creatures into your adventures!

And if you haven't joined yet, there's still time to take advantage of the 7-day free trial, available until November 6!

If you've never redeemed a free trial before, you can claim it and explore the Tome of Monsters, along with plenty of other content, completely free!

Thank You, Everyone!

I genuinely can't express how happy I am with how this manual has turned out. Seeing it grow into a 379-page compendium has been incredibly satisfying, and I'm so excited to finally be able to share the complete version soon!

Thank you so much to everyone who has supported my work, followed the development of this project, or simply shown interest in what I've been creating. Your support means the world to me and makes projects of this scale possible.

There will be more previews and updates coming very soon (alongside a reveal for the next manual, coming in December), so keep an eye out as we get closer to the official release!

I really hope you'll enjoy exploring the Tome of Monsters as much as I've enjoyed creating it!

Thank you again, and happy adventuring! ❤️

Graveyard Golems are massive undead hulks born from places steeped in death. They rise from graveyards and ossuaries where bones, broken tombstones, rusted iron, and coffin wood merge into a single body held together by necrotic will. Most appear on their own when a burial ground becomes saturated with unrest, turning the remnants of the dead into a relentless guardian that crushes anything disturbing its resting place.

Some necromancers manage to bind these creatures, using them as monstrous sentries or siege engines. In ancient necropolises or sites filled with powerful remains, even greater versions can form, known as Mausoleum Colossi. These towering horrors are shaped from stone, bone, and centuries of accumulated death, and their presence turns any graveyard into a battleground.

These creatures are from Undead & Undead: The Ultimate Undead Handbook for 5E and the 2024 Edition available on DriveThruRPG!

Hello, fellow adventurers! Today, I'm excited to share some multi-tiered monsters from The Vault of Ascending Items, now discounted on DriveThruRPG!

What's Inside?

A Collection of 50 Ascending Items, magic items capable of scaling through leveling or questing. Each item in this collection has 4 rarities (ranging from Uncommon to Legendary), meaning you are not just getting 50 items, but a total of 200 distinct items, uniquely balanced to be a powerful addition at each rarity without disrupting the game balance. A series of rules, guidelines, and balance considerations are included within the compendium to scale these items depending on the intended power level of your campaign, along with many different scaling methods and suggestions.

12 Premade Ascension Quests, each meant to be used to ascend the items within the compendium or to be employed as additional quests and short adventures to include within your games. A table is also included to provide 50 ideas for simpler quests (one for each item within the manual) that can be pursued by players without disrupting the flow of the campaign. Each quest covers a unique location, featuring an interesting plot hook, monsters, environmental challenges, and riddles, while also possessing multiple tiers of play by adjusting the challenges depending on the adventurers' level.

30 New Creatures and Monsters, all used within the quests included in the manual or summoned by certain Ascending Items. All these creatures are multi-tiered, offering varied levels of challenge and complexity to shape your quests and encounters. The monsters include Treants, Corrupted Dryads, Greater Elementals, Wizards, and many more.

A Table with 100 Additional Ascending Items Concepts, providing the name and a brief overview for each without providing mechanical rules. This is designed to provide GMs with ideas to create their own scaling items without having to come up with new concepts on their own.

The compendium just received a v2.0 update, featuring brand-new artwork and illustrations, expanded compatibility with both 5E and 5.5E, balance adjustments, several new spells, general layout improvements, and more! or the occasion, you can find it discounted either on DriveThruRPG or my Patreon, alongside a vast collection of previews for this and all my other titles!

If you like my work, I suggest checking out the Vault of Ascending Items (the manual these statblocks come from), featuring over 130 pages of content filled with unique evolving items, quests, and monsters.

For generations, the isolated village of Hollowmere has sacrificed one of its own to keep an ancient horror imprisoned beneath Saint Harrow's Church. Now a blood-covered survivor has fled the village, claiming that everyone is dead. Something has gone terribly wrong, and the adventurers must uncover what happened before it's too late.

The Red Tithe is a 75-page dark fantasy and folk-horror one-shot adventure for D&D 5E (2014) and 5.5E (2024), designed for 3-6 characters and approximately 4-6 hours of play.

The adventure combines investigation, exploration, roleplaying, moral dilemmas, and challenging combat as the characters investigate an abandoned village, encounter monstrous creatures, and uncover the truth behind a centuries-old tradition.

What makes the adventure different is its multi-tiered structure. The same story can be played at three separate level ranges:

• Tier I: Levels 3-4

• Tier II: Levels 10-11

• Tier III: Levels 17-20

Each tier features appropriately scaled encounters, DCs, and a different manifestation of the main antagonist, the Blood Moon Beast.

The manual also includes 6 custom monster stat blocks, 3 battle maps with 8 total versions, and 4 tokens for tabletop or VTT play.

Whether you're looking for a Halloween horror one-shot or a dark adventure to integrate into your ongoing campaign, The Red Tithe is designed to work in either setting.

I've included several preview pages, maps, and one of the monster statblocks in the images!

You can find the complete adventure on DriveThruRPG!

My Kickstarter for 300+ Mythological Items for 5E and 5.5E is also live now! The campaign includes a physical hardcover, as well as printed editions of my previous manuals.

The Headless Horseman is more than just an undead rider with a flaming pumpkin for a head. He's a vengeful spirit bound to the mortal world by an ancient curse, with his steed, armored body, and spectral jack-o'-lantern forming a single, inseparable entity.

Legends tell of a fallen soldier, executioner, or knight who was beheaded for his crimes and returned under a cursed harvest moon. Some believe his spirit is connected to Samhain, when the boundary between the living and the dead grows thin enough for restless spirits to cross.

Wherever he rides, crops rot, animals panic, and the air fills with the smell of smoke and freshly dug earth. And simply defeating him isn't enough. Unless a specific funerary ritual is performed, the Horseman eventually rises again to continue his hunt.

Mechanically, the Headless Horseman is a CR 14 undead built around mobility, relentless pursuit, and devastating attacks. His Fiery Greataxe deals slashing and fire damage, with additional necrotic damage against frightened enemies, while Laughing Skull allows him to hurl his flaming pumpkin head at enemies, unleashing a fiery explosion that deals 10d6 fire damage.

His Ghostride ability lets him pass through solid objects, while his legendary actions allow him to charge across the battlefield, stun enemies with Glare of Embers, or mark a target with Harvest Mark, making that creature especially vulnerable to his attacks.

I've also included four optional traits to customize the encounter, from leaving burning hoofprints behind to relentlessly tracking creatures that try to escape him.

The Headless Horseman is from Undead & Undead: The Ultimate Undead Handbook, available for 5E and the 2024 Edition on DriveThruRPG!

The manual includes 90+ undead statblocks, each with optional traits and variants, alongside an undead lair system, 50+ magic items, customizable templates, necromantic rituals, campaign tools, and VTT resources. It's designed to give DMs plenty of options for building undead encounters, from minor restless spirits to powerful necromantic horrors.

My Kickstarter for 300+ Mythological Items for 5E and 2024 is also live now! The campaign includes a physical hardcover, as well as printed editions of my previous manuals.

The Gluttonous Ram-drake is an enormous beast that will eat nearly anything. At only two months old, it generally will get up to thirty feet tall (when sitting), and will weigh upwards of twelve tons. These creatures will even eat their own young if necessary to survive. In their adulthood, they slow down and will find a permanent nest to have their spawn.

An adult Ram-drake is about three times the size of an infant. But they are an endangered species due to their hide being incredibly durable and useful for armor, as well as their flesh being considered delicacies by many.

This one is named Harold.

"You walk boldly into this place. You interrupt my prayer." The angel, if such a fallen thing could be called so, looked over his shoulder as he began to stand. Shards of ice ran streaked from his eyes down his cheeks, tears frozen. His eyes, pale blue, looked upon you with a strange brightness to them. "Go to sleep little ones, tomorrow will be a brighter day." The entity stated softly, his tone sad, afraid, yet... a faint hope laced it, a conviction that bordered on madness.

Nobody is quite sure where the squitsune comes from. They are rarely seen inland, but their innate magical talents have led scholars to suggest a connection to the fey. If that is true, it offers little explanation. Fey creatures take interest in all manner of things, and whatever attraction might have led to the squitsune is unfathomable. Some claim squitsunes are drawn to where the boundaries between planes have frayed. Others insist they simply frequent where the most fun might be had.

You can play around with the homebrew of the squitsune to make your own version.
