Misdreavus, a nefarious banshee, evolves into Mismagius with the aid of a rare stone filled with concentrated darkness. Once applied, Misdreavus's dark power increases, transforming it into a ghostly mage. Mismagius doesn't learn any amazing new attacks or anything by levelling, but some hidden abilities can be unlocked with the help of the Move Relearner and a handful of Heart Scales. This witch builds on the power of an already versatile and popular Pokémon.
