The Heir of the Crazy Necromancer.
It wasn't just a title that Michel got when he met the Crazy Necromance, It was a symbol. A symbol representing the blood and Power of the Crazy Necromancer.
Just the initial powers he got due to that title were bountiful!
<Necromancy>, that helped him to conjure the dead.
<Skeleton summon> to summon the dead into skeletons.
<Blazing skull>, a skill that he enabled him to summon a flaming skull.
<Bone embrace> to call upon the white bones from the underworld to restrict the enemies.
<Reanimate> to recreate the summons.
<Undead confederate> to increase his regeneration and recovery.
and even the dominance stat and Necrotic energy!
Any one of those skills was enough for the average climbers of the Tower to go crazy over it but Michel had gotten all of them at once due to his Crazy Grandpa who was obsessed with passing down his powers to only his descendants.
