As an action, you can control any freestanding water within 90 meters inside an area you choose that is a cube up to 36 meters 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 9 meters. If the area includes a shore, the flooding water spills over onto dry land.
If you choose an area in a large body of water, you instead create a 9-meter tall wave that travels from one side of the area to the other and then crashes down. Any Huge or smaller vehicles in the wave’s path are carried with it to the other side. Any Huge or smaller vehicles struck by the wave have a 25% 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.
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.
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.
