The Mighty Legendary Fantastic Bombastic Destructive Lovely Beautiful Sexy Magic Missile is a weapon originates from the game Miasmata.
During the Miasmata stream, there was a creature that wanted to kill Mike. He threw a flaming stick at it and it ran off like a pussy. After that, he continued training and harnessing the Magic Missile to further strengthen its destructive capabilities.
Did I seriously write that holy shit. EDIT: I forgot to add, burn it with fire until nothing is left (along with this wiki)
