Rallying Standard

Wondrous item, rare (requires attunement)

A waving banner portraying the heraldry of home can bolster wavering courage. This battle standard has been infused with courageous magic and musters the willpower to fight ferociously. When an allied creature starts its turn in a space adjacent to you, it may make a single melee attack as a bonus action during their turn. This is separate from any attacks that they make during their turn. For you to grant this ability, you must wield the standard either in one hand or strapped to your back.
