Helm of the Aquilifer

Wondrous item, rare (requires attunement)

At the head of a Roman legion is a standardbearer wielding the sigil of an eagle. These soldiers, known as aquilifers, are signified by the animal pelt strapped to their helmets — most commonly a wolf, bear, or lion. The eagle of Rome must never be tarnished, therefore the aquilifer’s duty is to remind their legion that they must fight with ferocity to protect the eagle standard at all costs. While you are wearing the helm, all friendly creatures within 30 feet gain advantage on Dexterity and Constitution saving throws. As an action, you may inspire your allies within 60 feet and grant them temporary hit points equal to your proficiency bonus. Once you use this ability, you cannot use it again until you finish a short or long rest.
