In A World Of Darkness...
Celerity

This Discipline explains the superior quickness of vampires. A rating in Celerity allows a vampire to move extremely quickly in times of stress and take multiple actions in a single turn. While anyone can decide to split their Dice Pool during a single turn, a character with Celerity can perform extra actions without penalty. The blood point must be spent on the turn before Celerity is activated.  One extra action is allowed per point of Celerity, and the vampire may use his/her entire dice pool for each one. One Blood Point must be spent every turn that the character uses Celerity, even if he does not take all the actions allowed.
