Face Eater (5e Creature)
From D&D Wiki
Tiny monstrosity, unaligned
Skills Stealth +6, Perception +4
Ambusher. The face eater has advantage on attack rolls against any creature it has surprised.
Damage Transfer. While attached to a creature, the face eater takes only half of the damage dealt to it, rounded down, and the creature it is attached to takes the other half.
Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) piercing damage. If this attack was made with advantage, the face eater latches onto the target's head, and the target is blinded and cannot breathe or speak. While attached, the face eater can make this attack only against the target and has advantage on the attack roll. The face eater can detach itself by spending 5 feet of its movement. A creature, including the target, can take its action to detach the face eater by succeeding on a DC 13 Strength check.
Bile Spray (Recharge 5-6). The face eater injects acid into a creature it is attached to. That creature must make a DC 13 Constitution saving throw, taking 14 (4d6) acid damage on a failed save, or half as much damage on a successful one.
The face eater is a hateful abomination designed by a mad wizard who made their home in the blackest pits of the Underdark. Essentially a miniaturized Cloaker, they were released in droves to keep the surrounding tunnels clear of vermin. It is said that not a month went by before that same wizard fell prey to his own creations.
Treacherous Visage. Face eaters resemble a hybrid fusion of bat and moth, gliding silently through the darkness in the caverns they call home. Their fleshy wings bear mask-like patterns, which they can shape to a limited degree to more closely resemble the surfaces they land on. They have no eyes, instead sensing their environment through movement, and their underside is one long orifice that acts as both mouth and stomach. To feed, they latch onto a creature and eject acid into its flesh.
Devouring Swarm. Face eaters are rarely found as solitary predators. Though they will hunt alone in lean times, they nest in groups of at least half a dozen, usually in tight, nigh-unreachable crevices. When faced with a large enough enemy, they will descend en masse and devour them whole, leaving nothing but a bile-drenched skeleton.
