Wizard Subclass: The Twisted Weaver of Curses

 (this one, some chatgpt)

Stolen Knowledge
Beginning when you select this school at 2nd level, choose up to two skills from the wizard list with which you are proficient. You gain expertise with these skills. (If you have expertise with a given skill, your proficiency bonus is doubled for any ability check you make that uses that skill.) When you fail a skill check that uses your expertise, you take d10 psychic damage and are incapacitated for one minute, or until you succeed a wisdom save against your own spellcasting DC at the start of your turn.

Cruelty Incarnate
At second level, you gain a limited resource, known as Cruel Barbs. When you cast a spell that deals damage, you can choose to expend one Cruel Barb to weave a minor curse into that magic, dealing an additional 1d6 necrotic damage to one target of the spell. You may use this feature a number of times equal to your Intelligence modifier (or a minimum of 1 time), and regain expended uses on a short rest. The necrotic damage increases to 2d6 at level 5 and 3d6 at level 10.

You learn the Vicious Mockery cantrip, which counts as a wizard cantrip for you. If the target of your Vicious Mockery fails to hit with their next attack before the end of their next turn, you can regain one Cruel Barb.

You also learn the Hex spell, which counts as a wizard spell for you and doesn't count against your number of spells known. You may cast Hex once per short rest without using a spell slot. If you witness when the target of your Hex fails a skill check using the ability that you chose when you cast it, you may deal them 1d10 psychic damage, and may regain as many hit points as the psychic damage dealt.

Aura of Malfeasance
Starting at 6th level, you exude an unsettling aura. Creatures within 20ft of you have disadvantage on saving throws made against your spells and your other magical effects. Creatures that would be immune to the damage of your spells, within this area, are resistant instead.

Hex Mastermind
Starting at 6th level, when you cast the Hex spell, you may add additional targets to the spell. For each level of spell slot over first, you may add up to two additional targets.

Unfoolable Tricker of Tricks
At 10th level, you gain resistance to necrotic, acid, and poison damage. You gain advantage on saving throws against any effects where a failed save would leave you charmed, dominated, blinded, frightened, unconscious, or poisoned.

Cruelty Incarnate (Recharge 5-6). The Twisted Weaver of Curses can unleash a surge of malevolent energy. All creatures within 30 feet of the Weaver must make a Wisdom saving throw (DC 15) or take 4d6 psychic damage and be afflicted by the Hex spell. On a successful save, a creature takes half damage and is not hexed.

Aura of Malfeasance. Creatures within 20 feet of the Twisted Weaver have disadvantage on saving throws made against its spells and other magical effects. Creatures that would be immune to the damage of the Weaver's spells within this area are instead resistant.

Actions

Cursed Touch. Melee Spell Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (3d6) necrotic damage.

Vicious Mockery. Ranged Spell Attack: +7 to hit, range 60 ft., one target. Hit: 2d4 psychic damage, and the target has disadvantage on the next attack roll it makes before the end of its next turn. If the target fails to hit with that attack, the Twisted Weaver of Curses recharges its Cruelty Incarnate.

Reactions

Hexed Retribution. When a creature within 60 feet of the Twisted Weaver of Curses fails a skill check related to the ability chosen for the Hex spell, the Weaver can use its reaction to deal 1d10 psychic damage to that creature.

(as a song)

(Verse 1) In shadows deep, where curses creep, A twisted weaver starts to seethe, With magic dark, and words that bite, A sorcerer of the endless night.

(Chorus) Twisted Weaver, in the gloom, Draped in curses, like a shroud of doom, Spinning spells, a malevolent art, In the Weaver's web, where shadows depart.

(Verse 2) Stolen knowledge, a mind unbound, Expertise in curses that echo sound, Cruel barbs woven into the arcane, A dance of shadows, a sinister refrain.

(Pre-Chorus) Vicious Mockery, a taunting song, Hexes linger, as the night grows long, Aura of malfeasance, a chilling embrace, In the Weaver's presence, shadows encase.

(Chorus) Twisted Weaver, in the gloom, Draped in curses, like a shroud of doom, Spinning spells, a malevolent art, In the Weaver's web, where shadows depart.

(Bridge) Unfoolable tricker, resistant and sly, Hex master's gaze, a malevolent eye, Cruelty incarnate, a darkened mind, In the Weaver's realm, where curses bind.

(Verse 3) Hexed retribution, a psychic sting, In the web of curses, where echoes ring, A touch that curses, with every graze, A song of torment, in the shadowed maze.

(Pre-Chorus) Vicious Mockery, a taunting song, Hexes linger, as the night grows long, Aura of malfeasance, a chilling embrace, In the Weaver's presence, shadows encase.

(Chorus) Twisted Weaver, in the gloom, Draped in curses, like a shroud of doom, Spinning spells, a malevolent art, In the Weaver's web, where shadows depart.

(Outro) Beware the Weaver, with curses entwined, In the tapestry of shadows, where destinies find, A melody of malice, a darkened verse, In the Weaver's curse, forever immersed.
