Slime liches are the result of a twisted pact between a powerful wizard and Jubilex, the Demon Prince of Ooze. Seeking to escape death and gain immortality, these wizards undergo a ritual that transforms them into undead oozes, bound to a phylactery in the form of an oblex spawn. Slime liches retain their intelligence and spellcasting abilities, but also gain the traits of oozes, such as resistance to physical damage and the ability to secrete acid.
Slime liches are obsessed with expanding their knowledge and power, often by consuming the memories of other creatures. They use their phylacteries to store and access these memories, as well as to communicate with their patron Jubilex. Slime liches are loyal to Jubilex, but also seek to further their own agendas, which usually involve spreading corruption and chaos in the world.
Slime liches are rare and secretive, preferring to hide in remote locations where they can conduct their experiments and rituals undisturbed. They often have lairs filled with oozes and undead that serve as their minions and guards. Slime liches are paranoid and cunning, always prepared for intruders or enemies. They use their spells and lair actions to manipulate the environment and trap their foes.
Slime liches are feared and hated by most living creatures, who see them as abominations and threats. Only a few cults or factions may ally with them, either out of reverence for Jubilex or out of desperation for power. Slime liches have few rivals among other undead or oozes, as they consider themselves superior to both. However, they may occasionally clash with other powerful spellcasters or entities that seek to challenge or exploit them.
