Create My Monsters is the official Open Dungeons RPG monster builder. Whether you are a Dungeon Narrator designing original encounters or a player who wants to submit a creature to the Monster Trove, this tool gives you a fast, structured way to build any monster using the ODRPG stat block format - no spreadsheets, no guesswork.
How It Works
Every field maps directly to the Open Dungeons RPG rules system. Fill in your monster's identity, stats, save rolls, resistances, special attacks, and lore. The stat block preview updates live as you type, so you always see exactly what your creature will look like before you export.
When you are done, export your monster as a ready-to-use PDF stat block - formatted to match the layout of the official Monster Trove - First Encounters: Creatures for Early Adventures.
What You Can Build
Identity
Name your monster and set its size category. Large threats hit differently than small ones, and the identity section sets the stage for everything that follows.
Stats
Set Hit Points, Armor Class, Damage Reduction, number of attacks, and attack damage dice. These are the core numbers that define how dangerous your creature is at the table.
Save Rolls
Assign Quick, Tough, and Mind save bonuses. These three saves cover the full range of threats in ODRPG - from a rogue's sudden dodge to a cleric's iron will against a curse.
Resistances
Define what your monster shrugs off and what cuts through its defenses. Elemental immunities, damage reduction exceptions, and magical resistances all live here.
Special Attack
Give your monster a signature move. Venom, fire breath, a grapple that pins - special attacks are what make encounters memorable. Select from the built-in workbook or write your own.
Lore
The About section is your monster's personality on the page. A flavor cue that helps the DN bring the creature to life - its mood, its presence, the way it hunts. Keep it short and sharp.
Load from the Monster Trove
All 278 monsters from the official Open Dungeons RPG Monster Trove - First Encounters: Creatures for Early Adventures are available as a starting point - from Aberrant Hunter to Zombie. Use the Load Monster feature to pull up any creature from the book, then modify its stats, swap its special attack, or rewrite its lore to make something new. It is the fastest way to create a variant, a boss version, or a custom encounter built around a familiar creature.
Save Your Monsters and Submit to the Trove
Patreon supporters can save and reload monsters between sessions, building a personal library of custom creatures. Saves are tied to your Patreon login and persist across visits.
Saved monsters can also be submitted to the Monster Trove with creator credit. Open Dungeons RPG is a community-built game, and the Trove grows through contributions from DNs and players who love the system. If you build something great, share it.
