Ebon Tide

7th-level evocation

Range: 500 feet Casting Time: 1 action

Components: V, S, M (a bottle of shadows)

Duration: Concentration, up to 1 minute

You generate a wave of shadow matter at a point on the ground that you can see within range. For the duration, black winds and currents of shadow matter whip in a 100-foot-radius circle centered on that point, modifying terrain and sometimes drowning creatures in the area. The area becomes difficult terrain. Each creature touching the ground must make a Constitution saving throw. On a failed save, the creature gains a level of exhaustion. When you cast this spell and at the end of each turn you spend concentrating on it, each creature on the ground in the area must make a Dexterity saving throw. On a failed save, the creature is knocked prone.

The ebon tide deals 30 bludgeoning damage to any structure in contact with the ground in the area when you cast the spell and at the start of each of your turns until the spell ends. If a structure drops to 0 hit points, it sinks into the earth, consumed by the Shadow Realm. Any creature within a structure when it sinks must make a Constitution saving throw. On a failed save, the creature takes 2d12 necrotic damage, is knocked prone, and is blinded for 1 round.

On a successful save, the creature takes half as much damage and doesn’t fall prone or become blinded.

This spell can have additional effects depending on the terrain in the area, as determined by the GM. No more than two of the following effects can be the result of one casting of ebon tide.

Hills and Hollows. Ground rises or sinks throughout the spell’s area at the start of your next turn after you cast the spell. These changes take the form of a hill, a slip fault (a new cliff), or a hollow. A total of 1d4 such hills, slip faults, or hollows open in locations chosen by the GM. A hollow or slip fault that opens beneath a structure causes it to automatically collapse (see above). A hollow or hill can alter the flow of local water, such as a moat, stream, or lake.

Rivers, Shores, and Waters. Water in the area can adopt an old course (such as an oxbow) or be swept into a new one, starting at the start of your next turn after you cast this spell. Only one such water element can be altered by the casting of this spell. (You cannot alter both a lake and a stream feeding it, for instance.)

Shadow Mire. All ground in the area of the spell becomes shadow mire for the duration.
