Rampaging Circlet (Patreon)

Wondrous item, uncommon (requires attunement by a barbarian)

While wearing this circlet, you gain 5 temporary hit points whenever you enter a rage for the first time during a combat. You also gain 1d4 + 1 temporary hit points whenever you slay a creature while raging during combat. You lose these hit points if you have any of them remaining when combat ends.

My hunger for battle boils over, but it is endless. With every victory, I am renewed, yet never sated.
