Brisus

Brisus is an adaptation of Risus developed by Garrett. It was primarily born of want for a good Critical Hit mechanic for a dice pool system, which was replaced by a degree mechanic, in which the degree by which your task is succeeded or failed is determined by the margin by which the roll is succeded or failed. It also distinguishes between aggressive and passive rolls, something that the games prior used exclusively without realizing the rules were not meant for this, but it was decided to be the superior method. The rules in full can be accessed Here. Pictured is the Japanese experimental band Boris. I'm hilarious.
