World of Darkness: My Chicago
Resilience is a supernatural ability of the Kindred. One of the three common ‘physical’ disciplines, Resilience enhances Stamina like Vigor increases strength.
By using some of her blood the vampire extends her damage limit to supernatural limitations, allowing her to survive wounds that would cripple other vampires or force them into Torpor . Not only does the discipline make the vampire able to take more damage, it can downgrade aggravated damage, saving the user from wounds that would have long term effects and possibly saving them a great amount of time and Vitae. This downgrade may not sound like much but at higher levels when multiple aggravated wounds can be avoided the discipline is worth its weight in gold for a front line fighter or any Kindred looking to avoid being destroyed by fire.
