Actually wandless magic is weaker compared to wand magic. The hands are a terrible foci for your magic to pass through, that's why there are barely any wizards and witches that practice wandless magic.
actually that's wrong. the wand is a tool to focus your mind and energy on, it's especially good for children and discourages wild underage magic. wandless and also wordless magic is stronger because it's more natural. it's the mind and will that shapes the magic not the words and movements.
Wizards could magically give person a voice, be it through healing broken vocal chords or using potions to mend and build up the one a born-mute might have.

Dark wizard: *disintegrates
I was expecting Eminem or some other modern rapper not Busta Rhymes
Shame it's so anticlimactic and dull.
