Awakened Scaled Ornament (white)

Very Rare

Wakened Scaled Ornament (White Dragon Tooth Amulet) Wondrous Item, Very Rare (Requires Attunement) This ornament comes from the White Dragon Lodge, one of the oldest and largest berserker lodges in Rashemen. This white dragon’s tooth has been fitted onto a necklace and remains razor sharp. This ornament can be jewelry, a cloak, or another wearable accessory. It appears to be fashioned from a dragon's scale, tooth, or claw, or it incorporates images in those shapes. You gain a +1 bonus to AC, and you can't be charmed or frightened. Moreover, each creature of your choice within 30 feet of you has advantage on saving throws it makes to avoid being charmed or frightened or to end those conditions on itself. When you would take damage of the type dealt by the breath of the dragon in whose hoard the ornament became Wakened, you can use your reaction to take no damage instead, and you regain hit points equal to the damage you would have taken. Once this property is used, it can't be used again until the next dawn. This item cannot gain or lose power or change states unless a story award allows it to and describes how it happens.
