Special Traits

• Ambusher. In the first round of a combat, the scuttlebug has advantage on attack rolls against any creature it surprised. Hive Mind. The scuttlebug is immune to the charmed and frightened conditions while within 30 feet of at least one other scuttlebug.
• Illusory Appearance. The scuttlebug covers itself and anything it is wearing or carrying with its wings that makes it look like a large man of general size and humanoid shape wearing a cloak. The illusion ends if the scuttlebug takes a bonus action to end it or if it dies. The changes wrought by this effect fail to hold up to physical inspection. Otherwise, a creature must take an action to visually inspect the illusion and succeed on a DC 13 Intelligence (Investigation) check to discern that the scuttlebug is disguised.
• Pack Tactics. The scuttlebug has advantage on an attack roll against a creature if at least one of the scuttlebug’s allies is within 5 feet of the creature and the ally isn’t incapacitated. Pounce. If the scuttlebug moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 13 Strength saving throw or be knocked prone. If the target is prone, the scuttlebug can make one bite attack against it as a bonus action. Spider Climb. The scuttlebug can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check

Actions

• Multiattack. The scuttlebug makes two attacks: one with its claw and one with its sting.
• Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) piercing damage.
• Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) slashing damage.
• Sting. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) piercing damage, and the target must make a DC 12 Constitution saving throw, taking 10 (3d6) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.

About

What you took to be a man in a dark overcoat is actually a large, roach-like beetle standing on its hind legs. Its face splits to reveal an insectoid head and vicious mandibles.

Scuttlebugs are generally aggressive, seeking to subdue all they encounter. If they perceive even the slightest threat to their hive-city or to their king, they attack immediately and fight to the death. Scuttlebugs communicate through the hive mind. They cannot speak otherwise.

Scuttlebugs are wicked combatants, using claws, bite, and a poisonous sting all at once. Through the hive mind, they attack with coordinated and extremely efficient tactics.
