As an action, you choose an area of water that you can see within 5 meters and that fits within a 1-meter cube. You manipulate it in one of the following ways:

  • You instantaneously move or otherwise change the flow of the water as you direct, up to 1 meter in any direction. This movement doesn’t have enough force to cause damage.
  • You cause the water to form into simple shapes and animate at your direction. This change lasts for 1 hour.
  • You change the water’s color or opacity. The water must be changed in the same way throughout. This change lasts for 1 hour.

If you cast this spell multiple times, you can have no more than two of its non-instantaneous effects active at a time, and you can dismiss such an effect on your turn (no action required).

At higher levels

The cube increases by 1 meter when you reach 9th level (2 meters) and 17th level (3 meters).

Create Water. You create up to 40 liters of clean water within 5 meters in an open container. Alternatively, the water falls as rain in a sphere twice as big as normal within 10 meters. Any burning creature in the area stops burning and exposed flames in the area are doused.

Purify Water. All nonmagical liquid within a sphere within 5 meters is purified and rendered free of poison and disease.

As an action, you drain the moisture from a creature that you can touch or see within 10 meters. The creature must make a Fortitude saving throw, which it does with disadvantage if it is a plant creature, a magical plant, or a creature made of water such as a water elemental. If the creature has no moisture in its body, the spell has no effect on it.

On a failure, it takes 5d6 necrotic damage and is exhausted 1 until it rehydrates. This exhaustion does not accumulate with other forms of exhaustion due to dehydration.

On a critical failure, it takes twice as much damage and is exhausted 2 until it rehydrates. This exhaustion does not accumulate with other forms of exhaustion due to dehydration.

concentration, 1 hour/mana

As an action, you create a sphere twice as big as normal of fog centered on a point within 20 meters. The sphere spreads around corners, and its area is heavily obscured. It lasts for the duration or until a wind of moderate or greater speed (at least 15 kilometers per hour) disperses it. Creatures in the are have advantage on saving throws against the burning condition.

As a reaction, which you use when you are hit by an attack that you can see or when you take fire damage, you can create a rushing torrent of water as a shield. You have resistance to bludgeoning, piercing, and slashing damage from nonmagical weapon attacks until the start of your next turn, including against the triggering attack.

Additionally, you have resistance to fire damage and advantage on saving throws against the burning condition until the start of your next turn.

Augment

You can expend 1 additional mana to trigger the spell when a creature that you can see within 10 meters is attacked or takes fire damage. The attacked creature gains the benefits instead.

(ritual)

The spell ends if the target dons armor or if you dismiss the spell on your turn (no action required).

As a reaction, which you use when you are hit by an attack, jets of water shoot out from you. If the creature who damaged you is within 10 meters, it must make a Reflex saving throw.

On a failure, it takes 2d10 bludgeoning damage and is pushed or pulled 2 meters away from you or toward you if it is Medium or smaller.

On a critical failure, it takes twice as much damage and is pushed or pulled 4 meters away from you or toward you if it is Medium or smaller.

    Whenever a creature enters the area for the first time on a turn or starts its turn there, it must make the Reflex saving throw.

    You can change the direction of the waves as an action.

As an action, you unleash a jet of water. Each creature in a cone or line must make a Reflex saving throw.

As two actions, you, along with everything you’re wearing and carrying, transforms into a watery form. The spell ends if you drop to 0 health.

While in this form, the following rules apply:

  • your only methods of movement are a speed of 2 meters and a swimming speed of 5 meters
  • you can enter and occupy the space of another creature
  • you have resistance to nonmagical damage and are immune to the exhausted, grappled, paralyzed, petrified, poisoned, prone, and restrained conditions
  • you have advantage on Reflex and Fortitude saving throws
  • you can move through a space as narrow as 2 centimeters wide without squeezing.
  • you can’t talk, manipulate objects, attack, use maneuvers, or cast spells. Any objects you were carrying or holding can’t be dropped, used, or otherwise interacted with.
  • if you are burning, the condition ends.
  • the only actions you can take in this form are the Dash action or to revert to your normal form. Until the spell ends, as two actions, you can revert to water form.

If you are in water form and swimming when the effect ends, you ascend 10 meters per round for 1 minute until you reach the surface.

Augment
You can augment this spell with the following options, expending mana for each option.
  • You can target two additional creatures for each additional mana expended. The creatures must be within 5 meters of each other when you target them.

  • Water Glide. You can expend 1 additional mana to cast this spell without concentration and modify the effect so your swimming speed increases to 100 meters. You can target five additional creatures for each additional mana expended. The creatures must be within 5 meters of each other when you target them.

concentration, 5 minutes/mana

As two actions, you can control any freestanding water within 100 meters inside an area that is a cube up to 20 meters on a side. You can choose from any of the following effects when you cast this spell.

Flood. You cause the water level of all standing water in the area to rise by as much as 5 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 5-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.

On subsequent turns, you can use two actions to repeat the same effect or choose a different one.

concentration, 1 minute/mana

As two actions, you form a swirling globe of magical water around the head of a creature that you can touch or see within 10 meters. At the start of each of its turns for the duration, the creature must make a Fortitude saving throw. If the creature doesn’t breathe, the spell has no effect on it.

On a failure, it loses 3d8 health, is deafened, can’t speak, can’t use breath weapons, and can’t see anything beyond 2 meters until the start of its next turn.

On a critical failure, it loses twice as much health.

On a success, it loses half as much health and and the effect ends.

On a critical success, it loses no health and the effect ends.

Augment

You can cause the target to lose 3d8 more health for each additional mana expended.

As two actions, you draw the moisture from every creature at a point within 20 meters. Each creature in a sphere centered on that point must make a Fortitude saving throw, which it does with disadvantage if it is a plant creature, a magical plant, or a creature made of water such as a water elemental. If the creature has no moisture in its body, the spell has no effect on it.

On a failure, it takes 7d6 necrotic damage and is exhausted 1 until it rehydrates. This exhaustion does not accumulate with other forms of exhaustion due to dehydration.

On a critical failure, it takes twice as much damage and is exhausted 2 until it rehydrates. This exhaustion does not accumulate with other forms of exhaustion due to dehydration.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

The spell deals maximum damage to plant creatures, magical plants, or creatures made of water such as a water elemental.

Nonmagical plants that aren’t a creature, such as a tree or shrub, automatically fail the saving throw and withers and die.

Augment

You can increase the damage by 2d6 for each additional mana expended.

As two actions, you touch a creature and can remove the blinded, deafened, or poisoned condition.

Augment
You can augment this spell with the following options, expending mana for each option.
  • You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.

  • Greater Purification. You can expend 1 additional mana to instead remove any reductions to one of its abilities, remove one effect that reduces its maximum health, remove one effect that charmed, paralyzed, or petrified it, or reduce its exhausted level by one.

As two actions, you create a wave of water that crashes down at a point within 20 meters. Each creature in a sphere centered on that point must make a Reflex saving throw.

On a failure, it takes 3d8 bludgeoning damage, is knocked prone if it is Large or smaller, and is pushed 3 meters away from the center of the sphere if it is Large or smaller.

On a critical failure, it takes twice as much damage and is pushed 6 meters away from the center of the sphere if it is Large or smaller.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

Additionally, any burning creature or object in the area stops burning.

The water then spreads out across the ground in all directions, extinguishing unprotected flames in its area and within 5 meters of it, and then it vanishes.

Augment

You can increase the damage by 1d8, push each creature an additional meter, and affect a creature of a larger size for each additional mana expended.

concentration, 5 minutes/mana

As two actions, you create a wall of water twice as big as normal at a point you can see within 20 meters that lasts for the duration. The wall can’t occupy the same space as a creature or object and it needs to be vertical and to rest on a firm foundation. The wall blocks line of sight, but creatures and objects can pass through it.

A creature must spend 2 meters of movement for every meter it moves through the wall. A creature that enters the wall’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.

On a failure, it takes 2d8 bludgeoning damage and is knocked prone if it is Large or smaller.

On a critical failure, it takes twice as much damage.

On a success, it takes half as much damage.

On a critical success, it takes no damage.

Any burning creature in the area stops burning, any ranged attack that enters the wall’s space has disadvantage on the attack roll, and fire damage is halved if the fire effect passes through the wall to reach its target. Spells that deal cold damage that pass through the wall cause the area of the wall they pass through to freeze solid (at least a 1-meter square section is frozen). Each 1-meter square frozen section has 10 Defense, 1 Soak, and 15 Health. Reducing a frozen section to 0 health destroys it. When a section is destroyed, the wall’s water doesn’t fill it.

(ritual); 1 hour/mana

As two actions, you grant the ability to move across any liquid surface—such as water, acid, mud, snow, quicksand, or lava—as if it were harmless solid ground (creatures crossing molten lava can still take damage from the heat) to a creature that you can touch or see within 5 meters.

If you target a creature submerged in a liquid, the spell carries the target to the surface of the liquid at a rate of 10 meters per round.

Augment

You can target one additional creature for each additional mana expended. The creatures must be within 5 meters of each other when you target them.
