The pale flenser may at first look like nothing more than a strange fungus inhabitant of the Underdark, but in truth these cruel and hateful plants are fairly intelligent. Despite this intelligence, the pale flensers seem to have no interest in forming societies or achieving anything apart from frugal survival. More likely, the actual needs and desires of these fungi menaces are so alien in nature that they simply cannot be comprehended by humanity.

A pale flenser consists of a collection of bulbous, leathery, gas-filled bags, each of which is about the size of a human head. From atop this mass of bags seethes a writhing forest of hundreds of 15-foot-long, terribly thin tendrils. These tendrils are studded with tiny razor-sharp barbs. The whole mass is either pale yellow or pale brown in color; the tendrils are milky and almost translucent. The pale flenser's leathery bags quickly fill with volatile gas, allowing it to float on air currents. It can propel itself through the air with great speed by venting this foul-smelling gas.

A pale flenser weighs about 80 pounds. They communicate with others of their kind with a complex sign language; although understanding of the languages of other creatures is not above their intellect, it certainly seems to be above their interest.

Pale flensers can grow to Huge size. Once a pale flenser becomes Huge, it can no longer fly and gains a ground speed of 5 feet.
