Underdark Ravager (Fun)

Appearance
These dark green things are more like spiders than their usual millipede-scorpion mixture cousins. They skitter around on eight legs and have massive, tarantula-esque fangs. However, they do maintain the elongated tail, which ends in a grappling claw around a stinger.

Information
Underdark Ravagers live exclusively in Illusion Barriers that form in lightless cavities. They are the frequent doom of new Abyss adventurers, as these hard to catch predators manage to ellude groups or individuals that could actually hurt them by taking advantage of their species' ability to lurk in the darkness itself. Unlike most other Wall Shadows, the Underdark Ravager does not kill its prey by crushing it, but it instead injects a poison that liquifies bones, which it proceeds to drink, and then rips apart the remaining soft tissue.
