Endurance regeneration increased by 100%; stacks duration.
— In-game description
Vigor is a boon that increases the endurance regeneration rate, allowing affected targets to dodge more frequently. Vigor does not stack with other effects which increase endurance regeneration rate (such as from certain traits and signets). The endurance regeneration rate is capped at double the normal rate, which is most easily achieved when under effects of the vigor boon.
