Their oily vapor was still just as malodorous as the reeking of their sludge form. It had the same pillar like body 10 ft (3 m) high and 5 ft (1.5 m) wide in diameter, and could manifest several pseudopods at will. This form was a green cloud of murky smoke vaguely similar to that of its true form.

Yochlol were visually similar to alkilith in many ways, particularly in their ability to take on a gaseous appearance. This man-sized form appeared to be a massive black widow with a pair of dangerous fangs. Thirdly, yochlols could become giant arachnids with a leg span of 8 ft (2.4 m) and weighing 160 lb (73 kg). They could not morph clothes and so had to keep a pair nearby when entering this form. This form could not be crafted in such a way as to replicate other individuals and often was 6 ft (1.8 m) taller than the normal members of that race. Their most seen form however, was that of an attractive, slender human or elven female, normally a drow. This waxy exterior constantly effused a foul stench. They were visually akin to ropers, with eight writhing, powerful tentacles and a pillar-like main body with a single, sinister, scarlet eye in the middle. Their yellow, oozy, bodies seemed to be constantly melting and piling back up like a sickening living candle. In their natural form yochlols were, 6‒7 ft (1.8‒2.1 m) tall and weighed 250 lb (1,100 hg). Yochlols had four forms available to them: ooze, humanoid, spider, and gaseous.
