Elder Lich

Elder Liches (エルダーリッチ) are powerful immortal undead magic casters, capable of commanding lesser undead with their necromancy and casting highly destructive magic.

Background
A monster that spawns, when the corpse of an evil magic caster gains unholy life through sacrificial rituals. Due to their fearsome reputation known by the New World inhabitants, they see elder liches as the rulers of the undead. In YGGDRASIL, elder liches are referred as “white palter of false wealth”. There are also other subspecies that come in different colours such as “red palter of false wealth” and “black palter of false wealth”.

Appearance
An old and luxurious robe covered its body of rotting skins and bones. Holding a twisted staff adorned with gems on its end. Beneath its rotting exterior lies a pair of evil eyes brimming with intelligence. Its aura of negative energy covers its body like a thin fog, giving off a menacing atmosphere.

Abilities
Unlike normal undead, a Lich retains its intelligence. Thus, it's capable of complex thought. As a magic caster, the Lich's source of mana comes from negative energy power. However, it is poorly suited for melee battles. A lich is typically around level 30 and is ranked second among undead monsters.

Trivia

 * Apparently there is a ritual in the New World that allows one to become an Elder Lich, but the power to ascend or descend (depending on one's point of of view) to a lich requires the sacrifice of at least the entire population of a city.
 * Khajiit was attempting to turn himself into a Lich by sacrificing the entire population of E-Rantel.
 * Despite the fact that liches are said to be poor melee fighters, Momonga seems to have immense physical strength (though he lacks the skills of a real warrior) due to his high levels.
 * It would be challenging to defeat for a platinum-ranked adventurer, and relatively winnable for a mithril-ranked adventurer.
 * There is an infamous elder lich, who haunts the Katze Plains on a Ghost Ship that travel's around the fog banks that occur there. There is also another famous one which haunts an abandoned Castle.
 * Elder Lich is ranked middle within the hiearchy of the Elder Lich type monsters. While as a Skeleton Mage being the lowest, Overlord being the highest.
