Khymir: The Role-Playing Game
A fantasy RPG set in the city of Khymir and its environs in the world of Thorgon Karrelssa - the setting for Mark E. Rogers' books Zorachus¸ The Nightmare of God¸ and the Blood of the Lamb series. It uses a skill-based system where flat numbers are converted into die rolls. By default every 7 points of stat becomes 2d6¸ so if skill + modifiers is 15¸ that would be rolled as 2d6+1 and compared to difficulty. - A description from https://darkshire.net/jhkim/rpg/encyclopedia/ with kind permission of John H.
