Malefice Starting at level 1, you gain the ability to place a curse on a creature that you can see. As a bonus action, you can curse a creature that you can see, forcing it to make a Wisdom saving throw against your spellcasting DC. On a success, it knows only that you hate it vehemently. On a failure, it is cursed. While cursed, if the creature takes psychic damage then they must make a Charisma saving throw against your spellcasting DC, or be stunned until the end of their next turn. The curse can only trigger three times, fading afterward. It also fades if you complete a long rest. After you use this feature, you cannot do so again until you complete a short or long rest.

Midnight Pulse At 6th level and onwards, the darkness of your magic invokes the cruelty of the void. When a creature starts their turn within darkness created by a spell that you have cast, they must make a Constitution saving throw. On a failure they take 2d6 psychic damage, and on a success they take half as much damage. You and any creature that you summon are immune to this effect.

Vision of the Void Also beginning at 6th level, you can see through magical darkness.

Demonic Conversion When you reach 10th level, you learn the secret of turning your pain into a psychic curse. As a reaction when you take damage, you can force a creature that you can see to make a Wisdom saving throw against your spellcasing DC. If they succeed, then they take psychic damage equal to your warlock level. If they fail, then they take psychic damage equal to twice your warlock level. This damage cannot be reduced in any way. If you kill a creature through this, an Eidolon is created from their corpse. This consumes the corpse. The statistics for an Eidolon are at the end of this Otherworldly Patron description. If an Eidolon is created by this feature, you regain hit points equal to the damage you took to trigger this feature. After you use this feature, you cannot do so again until you complete a short or long rest.
