Lich
Liches are KonoSuba's Kings of the Undead, arch wizards who ritually abandon their bodies for immortality, gaining life-draining touches and command of the dead at the price of holy magic's wrath.
Necromancy in KonoSuba has a summit. A lich is a High-Ranked Undead, called the No Life King, produced when an arch wizard who has mastered the limits of magic abandons the natural body through arcane ritual and takes up kingship over the undead. Most keep a skeletal look, though the recently transformed, and those who keep feeding, pass for living. The transformation multiplies an already fearsome mage: liches drain life and mana by touch, inflict afflictions ranging from sleep to instant death with a hostile brush of the hand, shrug off ordinary weapons and most magic, and command ghosts and reanimated dead outright. The bill comes due against the divine, since holy water, priestly magic, and powerful purification burn them badly. Most liches begin as humans, but other races can manage the feat.
