Whenever you hit an enemy with a melee or a close attack, you gain temporary hit points equal to your Constitution modifier, plus any temporary hit points normally granted by the power. If you use an invigorating fighter attack power and miss every target with it, you gain temporary hit points equal to your Constitution modifier. When wearing light armor or chainmail, you gain a +1 bonus to damage rolls with melee and close weapon attacks whenever you have temporary hit points. This bonus increases to +2 if you’re wielding an axe, a hammer, a mace, or a pick.
Prerequisites: Dwarf, fighter, Battlerager Vigor class feature
Benefit: You gain a +2 feat bonus to the number of temporary hit points you gain from using an invigorating power. The bonus increases to 4 at 11th level and 6 at 21st level.
