Bake Cookies

A platter of cookies appears in an unoccupied space you can see. There are 1d100+20 cookies (each of which are 0.01 lbs), which last for seven days before going bad. For each set of five cookies eaten, you gain 3 temporary hit points, which last for 24 hours. 

If your concentration is broken while casting the spell, roll a d8. Depending on your roll, one of the following effects happens:

• 1-2: Your cookies are burned. The cookies' temporary hit points given becomes 1 per every five. 
• 3: Your cookies are underbaked. Each eater must succeed on a DC 13 Constitution saving throw or be poisoned, taking 1d4+2 poison damage. 
• 4: Your cookies have been burnt to literal crisps; they give no effect when eaten.
• 5-6: The cookies are different sizes. Each eater must eat 1d10 cookies to gain the same effect. Additionally, if the roll is 1 or 2, the eater must succeed on a DC 10 Constitution saving throw or take 1d4 poison damage.
• 7: It all becomes one massive cookie. Only one creature can eat it, and when eaten, it gives 50 temporary hit points. Really hope your party doesn't fight over it...
• 8: You're lucky. Nothing bad happened, except they look a little lumpy.
