Your service to your patron has granted you the ability to curse your enemies with pain and misfortune. As bonus action you can curse an enemy you can see for 1 hour. The cursed enemy takes additional damage from all your attacks equal to your proficiency bonus. If your attack does multiple different types of damage then you choose which type is increased. When you curse the target, choose one ability score. The cursed enemy has disadvantage on ability checks made with that ability. An enemy can only be affected by one of your warlock’s curses at a time and if you try to curse the target again then the previous curse immediately ends. The curse can be removed with the spells Remove Curse or Greater Restoration, or similar magic.
