Naruto: Rise of the Hidden World

You cause a forest of massive bone spikes to erupt violently from underground, creating a deadly terrain. All creatures in a 60 ft radius must make a Dexterity saving throw, taking 10d10 piercing damage on a failure and becoming restrained and bleeding, or half damage on a success without restraint. The area becomes difficult terrain, and you can meld into the bone forest, gaining +5 AC and attacking with advantage from any point inside. The effect lasts for 1 minute or until the bone spikes are destroyed.
