The ADOM Roleplaying Game (ADOM RPG) is based on the famous roguelike computer game ADOM (Ancient Domains Of Mystery) – one of the five foundational roguelike games. ADOM was initially released in 1994 and still is actively played by a large community (see the forums, Facebook, Twitter, blog and Steam page as well as its GOG page).
A sequel – Ultimate ADOM – is under development.

Your Campaign, Your Rules!

Fast & furious rules, vivid character generation, a flexible sandbox setting, all gathered under the hood of a modern, immensely readable & beautiful layout.

During the 2012 crowdfunding campaign that resurrected ADOM development we created the ADOM Lite RPG as part of the crowdfunding rewards. The new ADOM RPG is a completely reimagined and written from scratch rules system to finally realize the full potential of the world of ADOM and more than 27 years of active gaming history!

Ancardia is wrecked by an eternal war between the forces of Order and Chaos. Chaos tempts all living beings, slowly corrupting them by granting marvelous powers while at the same time changing your physique. ADOM RPG provides a unique corruption system that mirrors your growing power and deformation.

Non-Vancian Spell System

Most OSR games (as well as the granddaddy of all roleplaying games) use spell slots that are memorized daily. ADOM RPG goes a different route using a spellcasting system based on power points which are used to fuel (and push) your spells. Experience a totally new freedom of magic!

Core d20 Mechanic

All checks are resolved using one or two rolls of a d20. ADOM RPG combines the elegance of the advantage/disadvantage system of the fifth incarnation of the granddaddy of all RPGs with an amazing twist (not invented here) in order to fix problems inherent to said 5th edition system. Fast, furious, easy to use!
