Players choose their characters' name, gender, and class and beign at level 1 with a random amount of gold to purchase their starting equipment. Class determines which size die a character uses to gain hit points each level, and the specialist knowledge to which they have access. Multi-classing is possible.
Task resolution is performed by rolling a twenty-sided dice and adding the character's level (or half their level if the action does not fit with their class specialisms). If the result is equal to or higher than a target difficulty number (or 10 plus an opponent's level if in an opposed action) then the character is successful.
