Bleakheart 2014
CR 3 undead
Medium undead, neutral evil
While in dim light or darkness, the bleakheart is invisible.
The bleakheart’s innate spellcasting ability is Charisma (spell save DC 13). It can innately cast the following spells, requiring no material components: At will: detect thoughts, minor illusion 3/day each: disguise self
As a bonus action, the bleakheart can silently unlock a door within 10 feet of it that is held shut by a mundane lock. If a door has multiple locks, only one is unlocked per use of this trait.
While in sunlight, the bleakheart has disadvantage on attack rolls, ability checks, and saving throws.
Actions
Melee Spell Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (3d6) psychic damage.
Each creature of the bleakheart's choice that is within 20 feet of the bleakheart and aware of it must succeed on a DC 13 Wisdom saving throw or its Charisma score is reduced by 1d4. A creature that has taken psychic damage from the bleakheart's Disheartening Touch within the last minute has disadvantage on this saving throw. A creature that has its Charisma reduced to 0 ends its life at the earliest opportunity, and a new bleakheart rises from its corpse 1d4 hours later. Otherwise, the Charisma reduction lasts until the target finishes a long rest.
