You have become possessed by a horde of fallen goblin spirits who fill your thoughts and murmur battle hymns devoted to Maglubiyet in the back of your mind. When you enter battle, the horde’s voices become frenzied and excited, and the spirits rise to fight alongside you at Maglubiyet’s command. You have advantage on saving throws to avoid becoming possessed.

Additionally, whenever you take a bonus action to use your Nimble Escape trait, you can manifest the spirit of a fallen goblin to charge and attack a creature within 30 feet of you before dissipating. Make a melee spell attack against that creature, using Intelligence, Wisdom, or Charisma to do so (choose when you take this feat). On a hit, the target takes 1d6 necrotic damage, and the target cannot regain hit points until the start of your next turn. This damage increases to 2d6 when you reach 5th level, 3d6 when you reach 11th level, and 4d6 when you reach 17th level.

You can do this a number of times equal to your proficiency bonus, and regain all expended uses when you finish a long rest.
