Yamato

Conjuration Level: 2 Cast Time: 1 action Range: 30 feet Duration: Concentration, up to 1 minute You conjure a thick cloud of swirling, tinted smoke in a 15-foot-radius sphere centered on a point within range. The cloud heavily obscures the area, causing all creatures within it to make a Constitution saving throw at the start of each of their turns. On a failed save, they take 3d8 poison damage and are blinded until the start of their next turn. On a successful save, they take half damage and are not blinded. At Higher Levels: When cast using a spell slot of 3rd level or higher, the poison damage increases by 1d8 for each slot level above 2nd.
