Heisenberg

You are a master narcotic alchemist. 1d4 times per day (rolled at the start of each new day and reset at the end of each day) you can turn any 2 potions into a new, addictive substance with a new ability altogether.

Once done the 2 potions are mixed, they will no longer have their original contents and the new effect takes its place, you will not know the effect of the potion until after drinking it.

You must have proficiency with and own either a herbalist or alchemy kit and 2 potions of any kind.

Crafting time: 1 minute

Roll a d8 to determine your new creation:

1. Change-Or  You Polymorph into one of the following creatures: Chicken, Cat, Wolf, Owlbear (Roll 1d4 to choose and lasts 1d4 hours)
2. HaboScaro For 1d4 hours fire damage heals you rather than damages you 
3. Bulk-Up  Your AC increases by 1d4 for 1d4 hours

Once one of these concoctions is crafted. Whoever partakes must succeed a Constitution Saving Throw of DC12 or become addicted. For every 24 hours the addicted creature doesn't consume another narcotic drink or other form of narcotics they will suffer 1 level of exhaustion.

The spell Greater Restoration will remove all addictions.
