Playtest Wave 2! New Species & Subclasses Out Now!!

Playtest Wave 2: Part 1!
Hey everyone! I'm delighted to bring you Mythozoology Playtest Wave 2: Part 1! This is the first of two documents being released as part of this wave. This one updates the BETA PDF to include ALL character creation options from Ryoko's Forbidden Myths (aside from our original classes; the Bender, Tamer, and Maker are coming in a later update!)
Oniborne are back, baby!
If your order included Ryoko's Forbidden Myths, you will be able to find the updated BETA PDF on Backerkit to start playing right now! Please note, we haven't yet implemented your feedback from Wave 1 into the PDF yet, so material that was there before is unchanged at the moment.
In the updated PDF, you'll find the following new additions to explore
Species
Chromakin (with three subspecies) Nezukin Inukin (with three subspecies) Oniborne (with two subspecies)
Chromakin draw inspiration from Shodō, traditional calligraphy, with the various subspecies expanding into an exploration of different mediums of art. The inkborne gave us a design opportunity to give a loving nod to Final Fantasy's Black Mages, with a body formed of ink, a wide brimmed hat, and large gloves. Viva la Vivi!
Subclasses
Sorcerer: Tengu Sorcery Warlock: The Cartomancer Ranger: Orochi Conclave Paladin: Oath of Balance (formerly called Oath of Wild Magic) Cleric: Jiang-Shi Domain
+ Various New Spells
You're not ready for the Cartomancer Warlock. Oh, you THINK you're ready, but you're not. We went through a lot of options on bringing this subclass to life, optioning the use of traditional hanafuda and karuta cards as a game piece vs. more accessible playing cards. We've landed on a subclass that wields both dice and playing cards as game pieces for an experience unlike any other subclass, with a TON of references and cool mechanics built in to enjoy!
Next steps
The second part of this playtest wave will be new content for Heliana's Forgotten Monsters! The arrangers and artists are cooking on that right now, after being busy with this and another project I'm sure a lot of you have already seen (glances to the bottom of this update).
After the Heliana's PDF is updated with new material, the next Ryoko's playtest wave will include Armour Mastery mechanics, backgrounds, and the feats from Forbidden Myths, which will bring us to about 98% of player content in the entire book released. The Maker, Bender, Tamer, and bestiary will follow after that. I've also pretty much finished the Mech Manual, but the plan is to get the core books out to you first for maximum playtesting time, and follow swiftly with the other books.
Some mechs are truly MASSIVE, kaiju-battling warmachines! Others are speedier, two-pilot vehicles to dart around the battlefield. Can't wait to share the full rules expansion with you in the Mech Manual Playtest PDF!
My pal Pointy Hat has just launched his own Kickstarter, Wild Hearth, with Loot Tavern! Wild Hearth brings you tons of player options, a plethora of spells, a myriad of new monsters and items and expands your campaigns with new cooking rules, town building, farming, and traveling mechanics! Plus an all new NECROMANCER class, and tons more! You can check it out here, for that epic trailer animation if nothing else...
And as always, remember you can reach out to us directly for support at [email protected]
Take care and see you soon!

Playtest Wave 1 is LIVE!!!
It's Here!
Hey everyone! Mythozoology Playtest Wave 1 is now LIVE! It's like a much more beautiful Unearthed Arcana. That means, if you've filled out your Backerkit survey, you'll be able to download the playtest material from your purchased books that forms Playtest Wave 1! There's a ton of player material from Ryoko's Forbidden Myths, and 6 adventures from Heliana's Forgotten Monsters up right now.

Dragons incoming in the next week or two, complete with their adapting stat blocks and the Zodiac Domain system!
Your Feedback
Mythozoology is YOUR project! Your support has brought it to life, and you dictate the path we take when finalising the material across all books. The playtest PDFs all include a link to feedback survey where you can leave your thoughts and ideas; everything from spelling errors, formatting mistakes, balance tweaks, and positive comments on things you really love. We read all feedback and implement changes before the final release to ensure every book is the best it can be!
For example, I noticed only after releasing the playtest today that the Natsumin have a walk speed of an incredible 45 feet (it should be 35!) Never underestimate our ability to make a typographical error!
Survey Reminder
Remember, you won't be able to access your playtest material until your Backerkit survey is completed and your order has been locked (which we do every Monday night). If you need help with your survey,this update explains how to access your survey and fill everything out. We're always here to support if you need us, too, either at [email protected] or on the Loot Tavern Discord server.
Projects We Love - Free Stuff + 1,500 More Pages of D&D Expansions!
If you're enjoying Mythozoology and Ryoko's Guide to the Yokai Realms, you can grab 1,500 MORE pages of D&D Expansions I've created over on the DnD Shorts Patreon right now! By joining at the Red Dragon Tier, you get INSTANT access to over 25 full expansions, complete with Subclasses, Species, Feats, Rules Expansions, Maps, Spells, Ready-to-Play Adventures, and more, with stunning original art.
That's like 6 entire D&D books for £10, and I release a full additional expansion every month on there too. There's even three FREE expansions for you to check out on the Patreon right away. If you're a fan of the content I create for Ryoko's and Mythozoology, check it out for tons more awesome material for your games as well.
Hope y'all Americans had a wonderful July 4th, and we'll ping you with another update when the next wave of playtest material is finalised!
