Rank 3 Uktena Gift
The werewolf’s claws burn with mystic force, rending apart the delicate workings of magic. An ancestor-spirit teaches this Gift.
System: After the werewolf makes a successful claw attack, the player may spend a point of Willpower to end the effects of any ongoing magical power enhancing the target (such as the Gift: Razor Claws, or the Armor Charm). Permanent magical effects cannot be rent asunder by this Gift, nor powers that are innate to the nature of the target. For example, a werewolf’s Gifts could be cancelled, but not her ability to shapeshift; a vampire’s Disciplines could be disrupted, but not her immortality or her ability to spend blood to raise her Attributes. In the event that a magical effect mixes permanent and temporary elements, the permanent elements are retained while transitory elements are disabled. For example, a vampire’s Potence would continue to passively grant extra Strength dice, but blood could not be spent to transform those dice into automatic successes.
