A Taurethrim Pyramid Wraith is a skeletal dungeon mob similar in appearence to Harad Pyramid Wraiths added in Beta 25. They can only be summoned by opening the Stone Chests found deep inside Taurethrim Pyramids. After being killed, the stone chests are free to use.
These wraiths are very similar to vanilla skeletons in that they are affected by the smite enchant and are hostile to all players regardless of alignment.
Interestingly, this ghoul does not take damage from lava, nor by the fire caused by the lava. This has probably been implemented due to the vast amount of lava surrounding the treasure room, wherein the wraith spawns.
Regularly, they are seen bearing Taurethrim Equipment, with a matching dagger, chestplate, leggings, and boots; they do not wear helmets.
