Choker (5e Creature)
From D&D Wiki
Small aberration, chaotic evil
Spider Climb. The choker can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Tentacle. Melee Weapon Attack: +5 to hit, reach 10 ft., one creature. Hit: 7 (1d8 + 3) bludgeoning damage, and the target is grappled (escape DC 14). Until this grapple ends, the creature is restrained, and the choker can't constrict another target.
These small greyish-black humanoids generally roam underground in old caves and abandoned dungeons. They have long tubular limbs with tentacle-like fingers, perfect for latching on to unsuspecting prey in the darkness where they hunt. Chokers are generally solitary hunters and are very patient when it comes to ambushing targets.
