The Necromorph Tentacle is a grotesque, organic appendage with a segmented, muscular structure, resembling a twisted fusion of sinew and bone. Its surface is covered in a slick, dark membrane with visible veins and pulsating nodes, giving it a disturbingly alive appearance. The tip often ends in a sharp, bony protrusion or a splayed, claw-like appendage, designed for piercing or grasping prey.
