Hekireki (Celerity •, Vigor •)

Hekireki - 霹靂
(Celerity •, Vigor •)
This blend of supernatural speed and strength has your character put everything into a single, perfect strike. However, first she must remain calm, focusing and allowing her blood to channel and pool in preparation. It's alternatively referred to as 羽の飛翔, "hane no hisho," or "the feather's flight."
Cost: 1 Willpower; Special
Dice Pool: None
Action: Instant
To activate Hekireki, your character must take a full instant action and spend a single Willpower point. She cannot use Vitae during this turn for any purpose. Then, in following turns she can spend any number of Vitae, up to her normal per-turn limit dictated by her Blood Potency. During these turns, she may do nothing but defend herself. She can use her Defense, but may not Dodge. She may use Vitae for Celerity during this time, but it does not add to the total used on the Devotion. Once ready, she takes one single strike. This strike may be unarmed or with a Weaponry-based strike. Each Vitae spent adds +2 to the dice pool. While the initial Willpower point does not add to this dice pool, she may spend an additional Willpower for the normal benefits. Her Celerity adds to her dice pool as well. On a successful strike, her Vigor is added as weapon damage, and the strike causes lethal damage even if it would not normally (this includes Kindred victims). For every Vitae spent on the Devotion, your character suffers a single bashing damage from the strain to her body.
For example, a Blood Potency ••, Vigor •••, Celerity •• character using Hekireki could spend 2 Vitae on the turn after she activates the Devotion, 2 more the third turn, 2 more the fourth, then on the fifth turn her she could spend 2 more Vitae, one additional Willpower, and her attack would be made at +21 (+16 from the Vitae, +2 from Celerity, +3 for Willpower), and a successful attack would cause three additional lethal damage from Vigor. After the attack, she'd take 8 bashing damage.
This Devotion costs 2 Experiences to learn.
Note: The rough translation of this Devotion's common name is "Thunderclap". However, the New York Movement adopted the name given to them by the Tokyo Kindred.
