Lightning

When you hit an opponent with Lightning, you may choose to either blind the target for one full turn or stun her, causing her to lose her next simple action. If a character is hit by more than one lightning bolt in a single turn, she can suffer both of these effects, but cannot be subjected to the same effect twice in a single turn.

Spend 1 Blood and use your standard action to make an opposed challenge. If you succeed, you can strike your target with a bolt of lightning. Individuals struck by lightning suffer 4 points of normal damage. A lightning bolt can either come from your outstretched hand, or, if you are outdoors when you use this power, it can strike down from the clouds above.
