Chieftain's Tainted Shroud

This tattered shroud is made from dark, decaying fabric and is adorned with symbols of undead creatures. While wearing the Chieftain's Tainted Shroud, you gain a +1 bonus to AC. Additionally, once per long rest, when you are reduced to 0 hit points, you can instead be returned to 1 hit point as swirling shadows protect you from death, and you gain resistance to necrotic damage for one minute. However, your presence grows more unsettling to others; you have disadvantage on Charisma checks while wearing this shroud.
