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.
