Nitro-Fueled Mixology

"Mocktails, mixers, ice, and all that is nice. Quite the opposite of whatever unholy concoction it is that the blonde Homura is actually conjuring up whilst no one is looking. That intellect she had inherited from her mother, it may have provided her with the chance to become Solace's greatest chemist, and yet she decided against it, picking up bartending instead, to everyone's dismay."

—Arima Homura

As an action, you can expend a Channel Divinity, and cast the spell Tasha's Bubbling Cauldron without needing to provide its material components or spell slot.
The spell functions as normal, with the following exceptions: 

• It takes on the appearance of a bar with your own personalized motif. 
• The liquid within the cauldron can duplicate the properties of up to Very Rare potions of your choice.
• Each time you withdraw a potion from the cauldron, it can be different from the previous one. 
• You can withdraw a "Specialty Mix" potion from the cauldron, which counts as two potions for the purposes of the maximum number of potions that it can produce.

A "Specialty Mix" potion is a mix of two potions of your choice that the cauldron can duplicate, taking the longer duration of the two, with a maximum duration of 6 hours. Due to their volatile nature, they become inert and lose their magical effects if not consumed within 4 hours of being produced.
Whenever you withdraw such a potion, roll a 1d100 before consulting the following table for its additional hidden effect that is only revealed once consumed. Once that additional hidden effect has taken effect, that same "Specialty Mix" potion loses that effect.
