Elder Lich

Elder Liches (エルダーリッチ) are powerful undead magic casters capable of commanding lesser undead with their necromancy.

Appearance
An old and luxurious robe covered its body of 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 his 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 in 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.
 * It is commonly called by players in games as white fake rich man, as the jewels and gems they carry with them are all fake.
