The Twin-Heart Amulet

The Twin-Heart Amulet
Wondrous Item, Legendary (Requires Attunement by two creatures simultaneously)
This beautiful gold-and-silver amulet splits perfectly into two halves: one shaped like a blooming rose (Lytharia’s symbol) and the other like a stylized flame (Tav'ani’s symbol). Two players must attune to the halves together, symbolizing a bond of deep trust or playful partnership.

Once worn by the divine duo "Lytharia, the Zealous Melody" and "Tav'ani, the Mischievous Melody" the deities of music and performance, openly to symbolize their bond and partnership, but with the world becoming a place less fond of the gods, they choose when and when not to wear their paired amulets openly, but their hope is to one day find worthy adventurers to bestow them apon...

Uncanny Sync: While the two attuned creatures are within 30 feet of each other, they both gain a +2 bonus to AC and saving throws.
The Swashbuckler's Duet: If one attuned creature hits an enemy with a melee attack, the second attuned creature can use their reaction to instantly move up to half their speed toward that same enemy without provoking opportunity attacks.
Empathic Shield: When one attuned creature takes damage, the other can use their reaction to split the damage evenly between them, protecting their partner from taking a fatal blow.
