Night Terror
Tier 1 Epic divination
Casting Time: 1 action
Range: Special
Components: V, S, M (the skull of a creature that died from psychic damage)
Duration: 1 week
This Epic spell fills a creature’s dreams with traumatic events and horrific visions. Choose a creature known to you as the target of this spell. Creatures that do not sleep, such as elves, have Epic advantage on saving throws against this spell but are not immune to its effects, instead suffering the effects when they take a long rest. If you possess a piece of that creature’s body, such as a lock of hair, the creature attempts its saving throws against this spell with Epic disadvantage. This spell immediately ends if you cast it again before its duration ends.
Over the spell’s duration, you automatically sense when your target begins a long rest. While the target is resting in this manner, you may begin a short or long rest to enter a trancelike state. You are unconscious while in this state and still gain the benefits of that rest. In the trance, you may choose to inflict one of the following effects on the creature over the course of its rest.
Enervating Visions. You send the creature exhausting nightmares of starvation and weakness. The creature must succeed on a Wisdom saving throw or gain 1 level of exhaustion and gain no benefit from its rest.
Murderous Intentions. You force the creature to dream of its death at your hands over and over. When the creature next sees you in person, it must succeed on a Wisdom saving throw or take 8d6 psychic damage per day it has experienced these nightmares. A successful Wisdom saving throw halves the damage. If the spell ends before the creature sees you in person, this effect ends.
Torturous Impressions. You can injure the creature’s mind by forcing it to experience torture, dismemberment, and staggering pain. When the target finishes its long rest, it must attempt a Constitution saving throw. Record whether the saving throw was a success or failure. If the target fails three such Constitution saving throws over the course of the spell’s duration, it dies.
