Clarity (Rank 3) Edit
The Garou is able to see through fog, pitch darkness and even recognize illusions or invisibility. The Gift is taught by a Wind spirit.
The Garou rolls Perception + Enigmas (difficulty 7). If the Stargazer attempts to see through someone else's illusion, the number of successes must match or beat that which were achieved when establishing the illusion.
