Dark Sonata (Move)

Dark Sonata is a non-damaging Dark-type move. Together with the event in Madrigal Garden, it was meant to serve as a Pokémon Evoas crossover before the project was shut down.

Effect
When used, Dark Sonata will corrupt a target Pokémon into acting as a living substitute for Meloetta, sacrificing 1/4 of Meloetta's maximum HP to do so. The target Pokémon takes damage for Meloetta until it is broken in a manner similar to. Meloetta effectively obtains the type, stats, and moveset of the controlled Pokémon until that Pokémon is no longer capable of substituting for Meloetta.

Because this move essentially knocks out the opponent's Pokémon if it successfully activates, it is limited to one use per battle. It will also fail completely if Meloetta possesses less than 1/4 of its maximum HP.

Be warned that as of 1.4.9 it is still prone to bugs when used. Save often when using it.

Description
The user sings, corrupting the foe. It can only be used once per battle.
