Tsagoth

Tsagoth is an undead creature, a blood fiend.

Appearance
Tsagoth is huge with a purple-black scaly hide. His has a lupine muzzle with great fangs and red eyes. He has four clawed hands.

As a blood fiend he feeds on blood, preferably of other fiends.

Skills
Most wounds inflited on him will heal in mere moments.

Tsagoth can dissolve into vapor. In this form he can float along walls and ceiling, being not quite invisible but fairly inconspicuous while making not a sound or pass through cracks in the wall.

He is able to control one's mind.

As vampires prey on humans, so do blood fiends prey on demons and like vampires, Tsagoth can also transform other creatures into their likes, as he demonstrated on Mari Agneh.

Importance
In 1375 DR, Tsagoth is summoned into Thay to find Mari Agneh in order to kill Aznar Thrul.
