Thorny Crest Pendant

This pendant is shaped like a raptor's crest, made of gleaming green stone and intertwined with thorny vines. While wearing this pendant, you gain advantage on Dexterity (Stealth) checks made in natural surroundings. Furthermore, when you take damage from a creature that is within 5 feet of you, the pendant allows you to conjure a thorny burst that deals 1d6 piercing damage to that creature (the damage increases to 2d6 at 10th level). After using this ability, you cannot use it again until you finish a short or long rest.
