Swarm of Silk-Gnawers - AI-generated fantasy Monster

Swarm of Silk-Gnawers

Travelers in the Glimmerwood know that when the ground starts to sparkle, it is time to run. The Silk-gnawers do not kill quickly; they weave a prison around your very soul, turning your own movement into the signal that summons their mother.

Swarm. The swarm can occupy another creature's space and vice versa, and the swarm can move through any opening large enough for a Tiny spider. The swarm can't regain hit points or gain temporary hit points.
Web Sense. While in contact with a web, the swarm knows the exact location of any other creature in contact with the same web.
Silent Alarm. The swarm is magically linked to its Matriarch. When the swarm takes damage, the Matriarch is immediately alerted to the swarm's exact location.
Conductive Field. Any creature that starts its turn in the swarm's space has its speed reduced by 10 feet. If the creature is currently under the effect of a spell that requires concentration, it must succeed on a Constitution saving throw or lose concentration as the silk disrupts the flow of mana.
Gnaw. Melee Weapon Attack: to hit, reach 0 ft., one target in the swarm's space. Hit: 7 () piercing damage, or 3 () piercing damage if the swarm has half of its hit points or fewer. The target must succeed on a Strength saving throw or be restrained by magically conductive silk (escape ). While restrained in this way, the target's speed is 0 and they have disadvantage on Dexterity saving throws.
Static Discharge (Recharge 5-6). The swarm releases a burst of stored magical energy. Each creature in the swarm's space must make a Dexterity saving throw, taking 10 () lightning damage on a failed save, or half as much damage on a successful one.
Disperse. When the swarm is targeted by an area of effect spell that does not deal fire damage, it can use its reaction to spread out. It takes half damage from the effect, but its speed is halved until the end of its next turn.
