TextYou begin to merge your current plane of existence with a plane of elemental water in a 30-foot-radius, 60-foot- tall cylinder centered on a point that you can see within range. It is perpetually raining within this cylinder, and all nonmagical fires are extinguished. A creature that is wet within this cylinder has disadvantage on saving throws against cold or lightning damage. This water disappears when the spell ends or if it leaves the cylinder. When you cast the spell, and as your action each round for the duration, you can cause one of the following effects: • You magically conjure 1d4 ice mephits, mud mephits, or steam mephits (your choice) in unoccupied spaces of your choice within the cylinder. They are hostile to all creatures that are not elementals and act on their own initiative count. These mephits lack the Summon Mephits action. A mephit summoned in this way disappears when the spell ends or if it leaves the cylinder. • You mentally command all mephits summoned by this spell to immediately die, triggering their Death Burst traits. • You fill the cylinder with magical fog, as if by the fog cloud spell. This fog dissipates when the spell ends or when you dispel it as a bonus action, and can't be blown away by a strong wind. • You cause the water on all surfaces in the cylinder to freeze. These surfaces count as difficult terrain, and any creature that makes a Strength (Athletics) check, Dexterity (Acrobatics) check, or that takes the Dash action on an icy surface must make a Dexterity saving throw. On a failed save the creature falls prone immediately after completing the check or action and takes 1d8 bludgeoning damage. On a successful save, nothing happens.
