Elauria

You conjure a dense, unnatural black mist that engulfs a 20-foot-radius sphere centered on a point within range. The mist obscures vision and dampens magical senses, making it difficult to perceive anything inside. The area becomes heavily obscured (like magical darkness). Any creature that starts its turn in the mist must succeed on a Wisdom saving throw or be disoriented, having disadvantage on attack rolls and ability checks until the start of their next turn. Creatures attempting to cast spells inside the mist must make a Concentration check (DC 10) or the spell fizzles due to magical interference.
