Swarm Tactics (Trait). The K'lor'slug has advantage on an attack roll against a creature if at least one of the k'lor'slug's allies is within 5 feet of the creature and the ally isn't incapacitated.
Bite (Action). Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) kinetic damage, and the target must succeed on a DC 11 Constitution saving throw or take 10 (3d6) poison damage. 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.
