Ephemeral wisps of nature spirits dance about those you strike.
Benefit: When you use Vital Strike (or Improved Vital Strike or Greater Vital Strike), the creature you hit with the attack must succeed at a Will save (DC = 10 + 1/2 your character level + your Wisdom modifier) or be illuminated as if by faerie fire for 1 minute. You can use this benefit a number of times per day equal to your Wisdom modifier (minimum 1).
