Psionic Movement. Mind Crawler can innately cast the Levitate spell on itself at will without requiring any components. 

• If the Mind Crawler is at least 15 feet above a target, and is capable of falling within 5 feet of them, it can use its Body Slam action to fall without taking any fall damage and makes its Body Slam attack against that creature, dealing one extra die of damage on a hit. 

Neurological Degenerator. Mind Crawler telepathically feeds off of the neural power of weak-minded or wounded creatures around it. Living creatures within 5 feet of a Mind Crawler that have less than half of their maximum Hit Points, or that have their Intelligence Score between 2-7, start to lose control over the motoric functions of their body, resulting in tremors, jerks and other similar effects.
The affected creatures gain a -2 penalty to their Attack Rolls, Dexterity saving throws and ability checks and Concentration checks. 

Actions. Body Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 6 (1d8+2) bludgeoning damage.
