Compulsive Invisibility
This derangement manifests in users of Obfuscate who either have a touch of paranoia or who insist on walking around cloaked at every possible moment. In the end, the sufferer of this derangment cannot turn off her Obfsucate. The player may roll Willpower (difficulty 6) to have her character drop the Obfuscate for an important situation, but she will resume the invisibility at the earliest opportunity.
