By Alejandro Melchor, for the Nahual tribe.
When success is achieved in a Gnosis roll against a difficulty of the victim's Willpower, the Nahual can make all reflections of the vitim seem like a distorted, Wyrm-corrupted image. The more Rage (or less Humanity) the victim has, the more horrible the reflection is; each mirror, pond, glass and anything else that casts a reflection exaggerates grossly the darkness within. The duration is a day per success, during which travel to the Umbra is impossible. The victim must make a Willpower roll against the Nahual's Gnosis to avoid going insane.
