Ouroboros Tabletop Roleplaying Engine, Fourth Iteration

A rules engine for tabletop roleplaying in fantastic worlds, supporting fantasy adventures with light rules, tactical choices, and flexible stakes. When a significant action calls for a roll, the Guide outlines the objective, potential consequences, and possible outcomes. The player rolls a number of twenty-sided dice based on the relevant skill, with each die matching or rolling below the applicable attribute counting as one success.
