The Yugoloth is a guardian who is summoned by evil Wizards or Priests to guard something of great importance. The Yugoloth will defend it's charge with a great ferocity. There are three types of Yugoloth, but each group appears to be the same way.
They look like giant winged bears with ram like horns protruding from the top of their heads. The three groups of the Yugoloth are lesser, least and greater. The lesser and least groups can appear as frog like beasts with ram like horns or ape or boar like with the ram like horns.
All Yugoloth groups are immune to the normal spells such a charm, erase or life. They have an alignment of neutral, but are one of the most fierce in combat among all of the guardians.
The greater yugoloth are only summoned when something of extremely great value needs to be guarded. No living human has been known or legend to have ever survived an attack of a Yugoloth.
They cannot be destroyed save by the hand which created them, and they fight with claw like hands and spears of deadly accuracy. They can also breathe fire and the greater Yugoloth can cast fire, lighting and storm spells if the ability was given them upon their creation.
