Infinite Domains bills itself as a universal roleplaying system, adaptable to any genre and any game world.
Die-rolls determine ratings for eight basic attributes: Affinity, Control, Dexterity, Intellect, Speed, Strength, Vitality and Luck. Simple formulas determine Endurance, Movement, and seven other secondary attributes. A choice of career (Warrior, Professional, Magus) directs you to a selection of skills (Acrobatics, Riding, Brawling), purchased with points. Add physical characteristics (using the Height & Weight Chart and Appearance Table) and a personal history (consult the Family Background Table) and you’ve got yourself a PC.
In most cases, determining the outcome of a particular action requires a single die-roll. The relevant skill rating equals the base percent chance of success.
