Blade Chained Vitality

Channeling your divinely inspired power, you imbue your slashing weapon with radiant energy, enabling it to transfer life force in the heat of battle.

For the next two rounds, the chosen weapon gains an additional 1d4 radiant damage (+1 for every 3 levels above 2nd) on its attack rolls. The damage dealt by this radiant energy is then channeled back to you as temporary hit points, fortifying your vitality in the midst of combat.
