Reapersessor (5e Creature)
From D&D Wiki
Medium monstrosity, neutral
Mind Hive. The reapersessor has access to the memories of all minds it has copied; it can choose to replace its Intelligence, Wisdom, or Charisma scores with those of a creature it has copied, can use any skills they have, and knows any languages they know. If the reapersessor reduces a creature to 0 hit points with a melee attack, its mind is copied.
Slash. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 19 (3d10 + 3) slashing damage.
Sting. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 10 (4d4) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or become paralyzed for 1 round; unconscious creatures automatically fail this save. If a creature fails this saving throw 3 times, its mind becomes copied by the reapersessor.
A relic of ancient civilization, the reapersessor is a master of targeted extermination, and adds its kills to an ever-growing vault of artificial "ghosts." Not unlike certain arthropods, the reapersessor is a venomous, fluid-feeding predator, injecting prey with a concoction of paralyzing nerve toxins and digestive enzymes through its razor-thin, hollow beak. As it feeds, it probes the nervous system of its prey with a network of microtendrils and duplicates a complete map of the victim's mind to one of the many redundant brains housed in its colorful throat sac. A mind stored in a reapersessor has no consciousness of its own, but the monster may project a detailed holographic image of any being it has consumed, re-enact their past actions, and access a lifetime of stolen knowledge. The reapersessor's ghostly projections are typically employed to disorient and frighten prey, but may also enclose and camouflage small enough objects or communicate information across distances of several yards.
