'Death knight
This undead has been raised with various materials added to its body. Specifically focusing on materials related to other undead and death mana affinity. This is due to the greater strength of the bones added to the skeleton knight while it was being acclimated to the manas within it.
Because it has a greater affinity with death than other manas, it is able to resist many of the attacks related to death and more destructive undead focused skills. However, that makes it slightly weaker to those using healing magic and life mana. They are opposing natures.
It is physically more powerful because the bones and armor it wears are made from tougher skeletal remains of monsters. They were also condensed using various elemental manas to ensure that it hold greater elemental mana resistances.
