Naruto: Rise of the Hidden World

You create an enormous forest of flowering trees that release sleep-inducing pollen. All creatures in range must make a Constitution saving throw at the start of their turn. On a failure, they fall unconscious for 1 minute and can reattempt the save at the end of each turn. On a success, they become immune to the effect for the duration. The forest lasts for 10 minutes or until burned or dispersed, and creatures that sleep in the pollen regain no chakra or health.
