Greater Maelstrom
8th-level conjuration (Druid)
- Casting Time: 1 action
- Range: 300 feet
- Components: V, S
- Duration: Concentration, up to 1 minute
You create a 120-foot wide by 60-foot deep swirling vortex that forms in a water source you can see within range. If the water source isn't at least the size of the vortex, the spell fails. A creature in the water that is caught within 60 feet of the vortex must make a Dexterity saving throw. On a failed save, the creature is sucked into the vortex's swirling waters.
A creature that starts its turn within the vortex's swirling waters must make a Dexterity saving throw. On a failed save, the creature takes 2d6 bludgeoning damage, and it is sucked 10 feet closer to the vortex's center. On a successful save, the creature doesn't take damage, and isn't sucked closer to the vortex's center. In addition, the creature can use its action to make a Strength (Athletics) check to swim away from the vortex's center. On a success, the creature can swim at half its speed, unless it has a swimming speed, in which case it can use this full movement. On a failed check, the creature doesn't make any progress.
A creature that starts its turn in the vortex's center, must make a Strength saving throw. On a failed save, the creature takes 2d6 bludgeoning damage and it is sucked 10 feet below the water's surface. A creature that reaches the vortex's bottom, 60 feet below the surface, is ejected a further 20 feet from below the vortex's center.
