Dames of Asstoria: Core Rule Book
Forge your legend in a world where gods and monsters walk among mortals.
The Dames of Asstoria Core Rule Book is the definitive guide to Dead Tree Studios’ newest PG-13 high-fantasy TTRPG. Step into the land of Asstoria, where players take on the roles of Demi-Fauna — part-animal, part-divine monster girls — who embark on epic quests to earn prestige, renown, and ultimately, the honor of knighthood as a Dame.
Unique Gameplay System
Dames of Asstoria features a dynamic dual-dice system designed for both tactical combat and cinematic storytelling.
- Combat: Built on a d100 percentile system for precise, fast-paced action.
- Non-Combat: Uses a flexible d10 pool system. Players roll a number of dice equal to their skill or base stat and aim to meet or exceed a target number with a minimum number of successes.
Special Rolls:
- Rolling a natural 1 causes a critical failure, reducing your lowest success by 1.
- Rolling a natural 10 “explodes,” adding an extra die to your pool for more chances to succeed.
Example:
Khadija, the lamia, is attempting to lift a heavy rock. Her Strength is 4, and the target is two 6s. She rolls four dice and gets 1, 4, 6, and 10. The unmodified 1 lowers her lowest success (6 → 5), causing a potential failure — but her 10 explodes, granting an extra die that lands on a 6. With two dice reading 6 or higher, Khadija successfully lifts the rock with effort.
This balance of luck, risk, and reward keeps every roll tense and satisfying.
Build Your Perfect Demi-Fauna
Create your own custom character using mammalian, aquatic, avian, reptilian, and insect traits — or play as a human for a true challenge. Mix and match to become your ideal monster-girl waifu, complete with abilities, quirks, and powerful transformations.
Progress through a multi-class system called Disciplines, earning experience and unlocking unique abilities based on how you play. Combine skills and attributes to create distinctive hybrid classes and playstyles that reflect your character’s journey.
