Wondrous Item
Very Rare Requires Attunement
As an action, you summon the magic of the necklace. You gain resistance to piercing damage from non-magical attacks for 1 minute and you create an ethereal dragon head that floats around you. When a creature gets within 5 feet of you for the first time on its turn or ends its turn within 5 feet of you, it must make a Dexterity saving throw DC 15. On a failure, it takes 4d6 piercing damage that is magical. The ethereal head floats around you for 1 minute. Once you use this feature you can not use it again until you complete a long rest.
While attuned to the necklace you have advantage on all saving throws against fear effects.
A large tooth hangs from a gilded golden chain with arcane writing etched into it. It appears to be a tooth from an Adult dragon.
Cost: 26,000 gp
