Uropygus

A uropygus was a very rare and dangerous creature, commonly found in the Underdark.

Description
Uroypgi were the largest type of pedipalpi. They had spiny bone-armored pincers and feelers like the smaller types, but also had tails which resembled the stinger of a scorpion.

Combat
Uropygi fought with their two pincers and vicious bite. They could execute a gripping attack, and if the opponent could not escape it, they crushed and held in place for a series of bites.

As well as using their appendages, these creatures were also able to release poison gas thrice a day. The yellow, sultry and acrid gas would expand around a 20' radius sphere and those within would uncontrollably spasm and tremor.
