Breastplate of Command

Armor (breastplate), legendary (requires attunement)

This resplendent armor is chased with gold and bears a gilded insignia on the chest. It grants the wearer a +2 bonus to AC and also grants the wearer advantage on Charisma (Intimidation) and Charisma (Persuasion) checks. Allies within 60 feet that can see the wearer gain a +1 bonus on saving throws against fear, while the wearer and allies within 10 feet have advantage on such saves as long as they can see the wearer.

As a reaction, the wearer can utter a special command or warning to an ally within 30 feet when it makes an attack roll or saving throw, allowing that ally to add a d4 to its roll as long as it can hear and understand the wearer.

This has no effect if the target is already using a bardic inspiration die, bless spell, or similar bonus die on the same roll.

If the wearer casts a bless or heroism spell, as a bonus action they can affect one additional ally.
