The Mist Skeleton is the third miniboss in Sonata of Blood, and the first single miniboss.
The Skeleton will hop around, smashing the ground. Sometimes, he will drive his fist into the ground, and in doing this, he will create a ground shockwave. When damaged enough, he will split into leaves and float around, reforming later. His other attack is to summon poisonous mist faces. He has 4000 HP. His theme is Resonance of Malevolent Souls.
