Feral Lobotomy (Rank 5) Edit
With but a thought, the Garou can devolve an opponent's mind to that of an animal, effectively destroying his intelligence. A spirit servant of the Griffin totem teaches this Gift.
The player rolls Wits + Empathy (difficulty of the target's Willpower + 3, maximum 10), and spends a variable number of Gnosis. If successful, the Garou can destroy a target's Intelligence Attribute permanently. Two Gnosis points must be spent for each point of Intelligence destroyed, and the Garou cannot destroy more points than he rolls successes. Additionally, the target begins acting more animalistic with each point removed.
