Bar of Shockolate

This segmented bar of magical chocolate has the image of a jagged lightning bolt printed into its surface, and is covered in electric-blue foil.

This bar of chocolate has 12 chunks that make up its form. You can eat one as an action, and take 1d4 lightning damage. When you take this lightning damage, for the next minute, you may instead maximize the damage roll for any spell attack you make that deals lightning damage. If you attempt to eat another chunk of this chocolate bar before one minute has passed, you take an additional 1d6 lightning damage, with the die size increasing by one for every successive piece you eat after that.

Once you eat the last chunk, you get a small static shock from the foil before it crumples away from existence.
