I am throwing a spin on health potions from a particular city in my world. They act almost like normal but because they are so abundant,  everyone has them and everyone tries to get what they can out of it. 

Potions go for 80% of normal potion cost.

A potion of healing goes for 40g: 1d4+2 to your health and you have a side effect of smelling like the flavor of potion you took to those within 5 ft radius for the number of hours equal to the amount of d4 you rolled. 

As you go up in rarity the smell intensifies by 10 ft radius and the hours by number from dice rolled. Also, with any potion above standard, you gain, when you take it, an ability associated and stacking with Rarity.

Greater- 3d4+4 and you can see colors more vividly for a number of hours equal to the dice rolled

Superior- 7d4+8 and you can hear colors. Dark colors make a low hum, while bright colors make a slight screeching noise. 

Supreme- 9d4+20  you can tell the alignment of an individual based on how the individual wears the colors they choose.

Any critiques? Comments? Concerns?
