Channeling the chill of the grave, make a melee spell attack against a target within reach. On a hit, the target takes 1d10 Necrotic damage, and it can't regain Hit Points until the end of your next turn.
Cantrip Upgrade. The damage increases by 1d10 when you reach levels 5 (2d10), 11 (3d10), and 17 (4d10).
You point at one creature you can see within range, and the single chime of a dolorous bell is audible within 10 feet of the target. The target must succeed on a Wisdom saving throw or take 1d8 Necrotic damage. If the target is missing any of its Hit Points, it instead takes 1d12 Necrotic damage.
Cantrip Upgrade. The damage increases by one die when you reach levels 5 (2d8 or 2d12), 11 (3d8 or 3d12), and 17 (4d8 or 4d12).
A creature you touch makes a Constitution saving throw, taking 2d10 Necrotic damage on a failed save or half as much damage on a successful one.
Using a Higher-Level Spell Slot. The damage increases by 1d10 for each spell slot level above 1.
You weave together threads of shadow to create a sword of solidified gloom in your hand. This magic sword lasts until the spell ends. It counts as a simple melee weapon with which you are proficient. It deals 2d8 psychic damage on a hit and has the finesse, light, and thrown properties (range 20/60). In addition, when you use the sword to attack a target that is in dim light or darkness, you make the attack roll with advantage.
If you drop the weapon or throw it, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to cause the sword to reappear in your hand.
At Higher Levels: When you cast this spell using a 3rd- or 4th-level spell slot, the damage increases to 3d8. When you cast it using a 5th- or 6th-level spell slot, the damage increases to 4d8. When you cast it using a spell slot of 7th level or higher, the damage increases to 5d8.
For the duration, magical Darkness spreads from a point within range and fills a 15-foot-radius Sphere. Darkvision can't see through it, and nonmagical light can't illuminate it.
Alternatively, you cast the spell on an object that isn't being worn or carried, causing the Darkness to fill a 15-foot Emanation originating from that object. Covering that object with something opaque, such as a bowl or helm, blocks the Darkness.
If any of this spells area overlaps with an area of Bright Light or Dim Light created by a spell of level 2 or lower, that other spell is dispelled.
You open a gateway to the Far Realm, a region infested with unspeakable horrors. A 20-foot-radius Sphere of Darkness appears, centered on a point with range and lasting for the duration. The Sphere is Difficult Terrain, and it is filled with strange whispers and slurping noises, which can be heard up to 30 feet away. No light, magical or otherwise, can illuminate the area, and creatures fully within it have the Blinded condition.
Any creature that starts its turn in the area takes 2d6 Cold damage. Any creature that ends its turn there must succeed on a Dexterity saving throw or take 2d6 Acid damage from otherworldly tentacles.
Using a Higher-Level Spell Slot. The Cold or Acid damage (your choice) increases by 1d6 for each spell slot level above 3.
Each creature in a 30-foot Cone must succeed on a Wisdom saving throw or drop whatever it is holding and have the Frightened condition for the duration.
A Frightened creature takes the Dash action and moves away from you by the safest route on each of its turns unless there is nowhere to move. If the creature ends its turn in a space where it doesn't have line of sight to you, the creature makes a Wisdom saving throw. On a successful save, the spell ends on that creature.
Flame-like shadows wreathe your body until the spell ends, causing you to become heavily obscured to others. The shadows turn dim light within 10 feet of you into darkness, and bright light in the same area to dim light.
Until the spell ends, you have resistance to radiant damage. In addition, whenever a creature within 10 feet of you hits you with an attack, the shadows lash out at that creature, dealing it 2d8 necrotic damage.
You create a 20-foot-radius Sphere of inky fog within range. The fog is magical Darkness and lasts for the duration or until a strong wind (such as the one created by the Gust of Wind spell) disperses it, ending the spell.
Each creature in the Sphere when it appears makes a Wisdom saving throw. On a failed save, a creature takes 5d6 Psychic damage and subtracts 1d6 from its saving throws until the end of its next turn. On a successful save, a creature takes half as much damage only. A creature also makes this save when the Sphere moves into its space, when it enters the Sphere, or when it ends its turn inside the Sphere. A creature makes this save only once per turn.
The Sphere moves 10 feet away from you at the start of each of your turns.
A tendril of inky darkness reaches out from you, touching a creature you can see within range to drain life from it. The target must make a Dexterity saving throw. On a successful save, the target takes 2d8 necrotic damage, and the spell ends. On a failed save, the target takes 4d8 necrotic damage, and until the spell ends, you can use your action on each of your turns to automatically deal 4d8 necrotic damage to the target. The spell ends if you use your action to do anything else, if the target is ever outside the spells range, or if the target has total cover from you.
Whenever the spell deals damage to a target, you regain hit points equal to half the amount of necrotic damage the target takes.
At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.
An aura extends from you in a 10-foot Emanation for the duration. The aura prevents creatures other than Constructs and Undead from passing or reaching through it. An affected creature can cast spells or make attacks with Ranged or Reach weapons through the barrier.
If you move so that an affected creature is forced to pass through the barrier, the spell ends.
You unleash virulent magic on a creature you can see within range. The target makes a Constitution saving throw. On a failed save, it takes 14d6 Necrotic damage, and its Hit Point maximum is reduced by an amount equal to the Necrotic damage it took. On a successful save, it takes half as much damage only. This spell can't reduce a target's Hit Point maximum below 1.
Deathly power fills a 60-foot Emanation originating from you for the duration.
When you cast this spell, you can designate creatures to be unaffected by it. Any other creature can't regain Hit Points while in the Emanation. Whenever the Emanation enters a creature's space and whenever a creature enters the Emanation or ends its turn there, the creature makes a Constitution saving throw. On a failed save, the creature takes 3d10 Necrotic damage and has the Prone condition. On a successful save, the creature takes half as much damage and its Speed is halved. A creature makes this save only once per turn.
Magical darkness spreads from a point you choose within range to fill a 60-foot-radius sphere until the spell ends. The darkness spreads around corners. A creature with darkvision can't see through this darkness. Nonmagical light, as well as light created by spells of 8th level or lower, can't illuminate the area.
Shrieks, gibbering, and mad laughter can be heard within the sphere. Whenever a creature starts its turn in the sphere, it must make a Wisdom saving throw, taking 8d8 psychic damage on a failed save, or half as much damage on a successful one.
