Until the spell ends. you control any freestanding water inside an area
you choose that is a cube up to 100 feet on a side. You can choose from
any of the following effects when you cast this spell. As an action on
your turn. you can repeat the same effect or choose a different one.
Flood. You cause the water level of all standing water in the area to
rise by as much as 20 feet. If the area includes a shore. the flooding
water spills over onto dry land.
If you choose an area in a large body ofwater, you instead create a
20---foot tall wave that travels from one side of the area to the other
and then crashes down. Any Huge or smaller vehicles in the waves path
are carried with it to the other side. Any Huge or smaller vehicles
struck by the wave have a 25 percent chance of capsizing.
The water level remains elevated until the spell ends or you choose a
different effect. If this effect produced a wave, the wave repeats on
the start of your next turn while the flood effect lasts.
\textbf{Part Water.} You cause water in the area to move apart and
create a trench. The trench extends across the spell's area, and the
separated water forms a wall to either side. The trench remains until
the spell ends or you choose a different effect. The water then slowly
fills in the trench over the course of the next round until the normal
water level is restored.
\textbf{Redirect Flow.} You cause flowing water in the area to move in a
direction you choose, even if the water has to flow over obstacles, up
walls, or in other unlikely directions. The water in the area moves as
you direct it, but once it moves beyond the spell's area, it resumes its
flow based on the terrain conditions. The water continues to move in the
direction you Chose until the spell ends or you choose a different
effect.
\textbf{Whirlpool.} This effect requires a body of water at least 50
feet square and 25 feet deep. You cause a whirlpool to form in the
center of the area. The whirlpool forms a vortex that is 5 feet wide at
the base, up to 50 feet wide at the top, and 25 feet tall. Any creature
or object in the water and within 25 feet of the vortex is pulled 10
feet toward it. A creature can swim away from the vortex by making a
Strength (Athletics) Check against your spell save DC.
When a creature enters the vortex for the first time on a turn or starts
its turn there, it must make a Strength saving throw. On a failed save,
the creature takes 2d8 bludgeoning damage and is caught in the vortex
until the spell ends. On a successful save, the creature takes half
damage, and isn't caught in the vortex. A creature caught in the vortex
can use its action to try to swim away from the vortex as described
above. but has disadvantage on the Strength (Athletics) check to do so.
The first time each turn that an object enters the vortex, the object
takes 2d8 bludgeoning damage; this damage occurs each round it remains
in the vortex.
