"Your beloved Undead King took him away from me just like you tried to take my children away. I'm going to do to you everything I would have done to him if only Meln had the guts to fight me in person instead of using one of his pathetic clones."
Manohar had devised Full-Course Meal to fix the imbalance in an undead's blood core for a brief period of time, turning them back into living beings and making them easier to kill.
The spell owed its name to the fact that the god of healing overfed the blood core with light element without caring for its natural equilibrium. When light overpowered the darkness element, an undead would regain their mortality but also lose their powers.
Vastor had upgraded the spell, making it last longer, and added the slight alteration to the life force to ensure that his victims would become incapable of using any magical item they had brought with them.
