Brush Scuttler Soldier Swarm

Nature's Hide. While in one of their natural habitats, the scuttlers can attempt to Hide even when only lightly obscured by foliage, heavy rain, and other natural phenomena, and have advantage on stealth checks while around such effects.

Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Small creature. The swarm can’t regain hit points or gain Temporary hit points.

Swarm Tactics. If a creature ends its turn in the swarm's space, the swarm gains advantage on attacks against that creature until it is no longer in the swarm's space.

Multiattack. The swarm makes two attacks.

Rend. Melee Weapon Attack: +5 to hit, reach 0 ft., one target in the swarm’s space. Hit: 10 (2d6+3) piercing damage plus 7 (2d6) acid damage, or 6 (1d6+3) piercing damage plus 3 (1d6) acid damage if the swarm is Bloodied.

Avenging Swarm (2/Day). When another creature with the Nature's Hide trait within 10 feet of the swarm is hit, the swarm moves up to half its movement speed toward the creature that dealt the damage. If this movement leaves the creature within the swarm's space it attempts to swarm over the creature. Strength Saving Throw: DC 13, any creatures within the swarm's space. Failure: knocked Prone. Success: Nothing happens.
