Blind Senses. The grimlock can’t use its blindsight while deafened and unable to smell.
Keen Hearing and Smell. The grimlock has advantage on Wisdom (Perception) checks that rely on hearing and smell.
Nearly Mindless. The grimlock has advantage on saving throws against being frightened or charmed.
Stone Camouflage. The grimlock has advantage on Dexterity (Stealth) checks made to hide in rocky terrain.
Stone Club. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 7 (1d6 + 4) bludgeoning damage.
Mindless Rage. When the grimlock is damaged by a creature it can sense within 30 feet, it may immediately move up to its speed towards that creature and make two stone club attacks against that creature.
Until the grimlock falls unconscious or finishes a short or long rest, it has advantage on attack rolls made against the creature that triggered this ability and disadvantage on attack rolls against any other creature.
When a grimlock is lobotomized, it becomes a mindless, violent grimlock brute. Typically, the procedure is carried out by another grimlock, but occasionally a grimlock will perform the lobotomy on itself, presenting the removed portion of its own brain to one of its alien masters.
